## Description: The mission of Jena is the creation and maintenance of software related to Java framework for building Semantic Web applications ## Project Status: Current project status: ongoing Issues for the board: none ## Membership Data: Apache Jena was founded 2012-04-18 (12 years ago) There are currently 19 committers and 13 PMC members in this project. The Committer-to-PMC ratio is roughly 5:4. Community changes, past quarter: - No new PMC members. Last addition was Aaron Coburn on 2019-01-22. - No new committers. Last addition was Arne Bernhardt on 2023-07-11. ## Project Activity: Version 4.10.0 was released at he start of November. This is planned to be the last 4.x release of Jena, with the next version being 5.0.0. The git main branch is Jena5. Most of the intended work reported last quarter has been completed. There are development artifacts available. An email has been sent the users list to highlight the main points of impact. As well as moving to requiring Java17 or later, the server code is now based on Eclipse Jakarta. There has not been a need to continue the Jena 4.x line so far but the project could release on that branch if necessary after the release of Jena 5. ## Community Health: Activity has been at normal levels. There has been a small increase in questions from users coming via github issues. The users mailing list is maybe a little quieter, comparing the same month across 2023, 2022 and 2021. StackOverflow questions get answers from people outside the PMC and developer community.

The Committer-to-PMC ratio is roughly 5:4. Community changes, past quarter: - No new PMC members. Last addition was Aaron Coburn on 2019-01-22. - Arne Bernhardt was added as committer on 2023-07-11 ## Project Activity: Development is now around Jena 5, using the major version change for both external changes and code improvements External changes include building convenience binaries for Java17 in keeping with the project supporting two Java LTS; switching from javax.servlet to jakarta.servlet); update to Eclipse Jetty12; and removing a dependency from a project that is no longer active. Project development for Jena5 includes removing deprecated code and tidying up. There is a new standards compliant RDF/XML parser which is both faster and easier to maintain. ## Community Health: The community continues to answer questions on the users list. The dev list has been quieter because the project has moved some more automated email off that list, general seasonal effects, and because the Jena5 development has proceeded on github.
## Description: The mission of Jena is the creation and maintenance of software related to Java framework for building Semantic Web applications ## Project Status: Current project status: Ongoing Issues for the board: none ## Membership Data: Apache Jena was founded 2012-04-18 (11 years ago) There are currently 18 committers and 13 PMC members in this project. The Committer-to-PMC ratio is roughly 9:7. Community changes, past quarter: - No new PMC members. Last addition was Aaron Coburn on 2019-01-22. - Arne Bernhardt was added as committer on 2023-07-11. ## Project Activity: The project added Arne Bernhardt as a new committer. The project released version 4.8.0 on 2023-April-23 and 4.9.0 on 2023-July-08. Both releases included addressing security issues. The project is discussing version 5.0.0. There are two external changes in the Java ecosystem that affect the project - a new LTS version (the project policy is to support the last two LTS versions of Java) and the J2EE javax to jakarta package transition. The project may make other incompatible changes that affect Jena users who use the project as a code library. ## Community Health: One part of 4.9.0 is a significant contribution to re-implement the in-memory graphs. At the same time, the new implementations follow the W3C standards as closely as possible. In 4.9.0, the new implementations are "opt-in". Whether they become the default at 5.0.0 is not yet decided.

Last addition was Greg Albiston on 2019-07-08. ## Project Activity: This quarter has seen steady progress with several contributions from people outside the project. There has been a significant performance improvement to primary storage subsystem, developed after discussions with users. There is a maintenance effort to improve the maintainability of the RDF/XML parser. ## Community Health: Activity levels are normal. Contributions to the project and technical discussions come via GitHub, and a slight increase in the the use of Github discussions. There were already very few issues coming via JIRA even before the switch to the process for new accounts - from early Nov 2022 to March 2023 there were no new JIRA issues.

Last addition was Greg Albiston on 2019-07-08. ## Project Activity: Jena released 4.7.0. The release included feature contributions from 6 people who are not PMC members or project committers. The web site has also seen pull-requests from external contributors. This was a significant release with two major features. LATERAL is a addition to the SPARQL query language being developed by the semantic web community. RDF Patch is a file format for recording changes to RDF data and it can be used recording changes, incremental backup and also as part of high availability replication of Jena Fuseki triplestore instances. The project deal with one security issue in a component that was retired from Jena sometime ago. CVE-2022-45136 ## Community Health: The significant change in email on dev@ is in part due to the release because the project needed to address a random test instability. Otherwise, the quarter has been the usual situation of more user requests than can be addressed within the resources of the project.

Last addition was Greg Albiston on 2019-07-08. ## Project Activity: Apache Jena 4.6.0 was released on 2022-08-25 and version 4.6.1 released 2022-09-07 because of a major defect in the .0 release. ## Community Health: Almost all activity has moved to github issues with only an occasional JIRA issue. There are also user questions on github, as issues. The project is receiving a steady stream of PRs adding features, or proposing API/behavioural changes, that support certain users’ needs, without the contributors necessarily considering how they impact on the existing user community. These need to be balanced with ensuring that the general design of the system is not adversely affected for all users. This has led to design discussions both on-list and via GitHub issues that have either resulting in better general-purpose contributions, or identifying existing ways that Jena already enabled their underlying use cases.

Last addition was Greg Albiston on 2019-07-08. Ian Dickinson (ijd@) asked to leave the PMC due to a change of focus. ## Project Activity: Jena 4.5.0 was released on 2022-05-04. There were three ICLAs requested for some significant contributions in-progress. TWo have been filed; one has been affected by illness. ## Community Health: Jena 10th anniversary as a TLP was 18/April/2022. In the last board report, we got a request to hear about the activation of github issues. We also reorganised the emailing lists as well to have separate list for issues and JIRA, not using the dev@ list. As a project, Jena communications fluctuate so it isn't possible in 3 months to be completely conclusive on all points but the switch from JIRA to github issues has been remarkably complete and swift. Github issues were enabled at the beginning of May. * The use of github issues has quickly taken over from JIRA as the preferred route. (Jena still gets a few JIRA tickets.) * The dev@ mailing list has had much less traffic because of emails routed to other lists. * The project also enabled the github discussions area. This has seen some activity but not a lot. The users@ list has been relatively quiet. (Nowadays a significant number of Jena questions are on StackOverflow anyway.) * We have had more external contributors. * There has been several large, significant contributions on github. We can't conclusively say that it is related to the change but some of them are filed early - being worked publicly on the contributor's PR branch, rather than being finished work when the PR is opened. * We have put in github workflow templates for issues and pull requests. For PR's this includes a statement that the contributions are understood as being made under the Apache Contributors agreement. * The issues templates refer to the Code of Conduct.
## Description: The mission of Jena is the creation and maintenance of software related to Java framework for building Semantic Web applications ## Issues: There are no issues requiring board attention. ## Membership Data: Apache Jena was founded 2012-04-18 (10 years ago) There are currently 18 committers and 14 PMC members in this project. The Committer-to-PMC ratio is 9:7. Community changes, past quarter: - No new PMC members. Last addition was Aaron Coburn on 2019-01-22. - No new committers. Last addition was Greg Albiston on 2019-07-08. ## Project Activity: Jena 4.4.0 was released 2022-02-02. Key features of this release: * New triplestore (Apache Jena Fuseki) UI. The UI has been rewritten for improved maintenance and style. We now have much better management of dependencies, as witnessed by security advisories on the github repository. * Improved bulk loader. The database bulk loader has fixes and performance refinements. It has been used to load the full WikiData dataset. This has been a community effort to test and load large scale data in different hardware environments. ## Community Health: The development community has decided to enable some github features (issues and discussions areas) and reorganise the mailing lists. The dev@ mailing list was primarily JIRA messages; these have been rerouted to a specific jira@. We hope that having the github features will make it easier for external feedback and contributions. The existing channels of feedback and contribution continue - nothing has been closed down. The level of email on the dev@ list will fall dramatically. This will show up in next quarter's report. We hope this makes it easier for people to observe the project and also have project-wide discussions without the JIRA emails dominating the list.
## Description: The mission of Jena is the creation and maintenance of software related to Java framework for building Semantic Web applications ## Issues: There are no issues requiring board attention. In the last report, there was a board comment: """ bd: "Jena has a process for retiring modules: delete in git..." I'm not sure what you mean by "delete" but I think Apache code should remain available and easy to find "forever". """ Jena develops and releases from a single git repository with several maven modules. The source-release is produced using the Apache Parent POM and so it is a copy of the current state of the checked-out code of the repository at the release point. When we deprecate a module we use "git rm" and insert a README file informing users of the last point in Git history at which it can be obtained. See for example: https://github.com/apache/jena/tree/main/jena-spatial. ## Membership Data: Apache Jena was founded 2012-04-18 (10 years ago). There are currently 18 committers and 14 PMC members in this project. The Committer-to-PMC ratio is 9:7. Community changes, past quarter: - No new PMC members. Last addition was Aaron Coburn on 2019-01-22. - No new committers. Last addition was Greg Albiston on 2019-07-08. ## Project Activity: Releases: Jena 4.3.0 -- 2021-12-09. Jena 4.3.1 -- 2021-12-13. Jena 4.3.2 -- 2021-12-19. The day after Jena 4.3.0 was released, Log4jShell was announced. The PMC confirmed that Jena was vulnerable and stated the release of 4.3.1 the same day. Jena 4.3.1 released using the usual voting schedule. The PMC also agreed how to have a fast-track release should it be needed in the future. This was used for Jena 4.3.2 with log4j2 updated again. ## Community Health: There has been a significant increase in discussions about upgrading. The development community has been experimenting with loading wikidata (a large dataset from the Wikimedia foundation). This feedback has been used to improve the bulk loading of data into a jena RDF database. There is a new UI for the Jena Fuseki triplestore which replaces the quite old javascript with a more modern development process making it easier to keep the code up-to-date.
## Description: The mission of Jena is the creation and maintenance of software related to Java framework for building Semantic Web applications ## Issues: There are no issues requiring board attention. ## Membership Data: Apache Jena was founded 2012-04-18 (9 years ago). There are currently 18 committers and 14 PMC members in this project. The Committer-to-PMC ratio is 9:7. Community changes, past quarter: - No new PMC members. Last addition was Aaron Coburn on 2019-01-22. - No new committers. Last addition was Greg Albiston on 2019-07-08. ## Project Activity: Jena version 4.2.0 was released 2021-09-12. It fixed CVE-2021-39239, which was discovered by the team, and affects all versions 4.1.0 and earlier. The release was not just about a CVE fix. The release included a new component, a data validation engine for the ShEx language to go alongside the SHACL engine. It also includes support for reading JSON-LD 1.1 using an external 3rd party library. JSON-LD 1.1 is used by some IOT device and service descriptions. During the release checking, a problem was discovered in the OSGi bundle related to the new dependencies for JSON-LD 1.1 handling. The project dropped the OSGi convenience binaries, and a discussion has started about retiring them. The development community no longer has the skills, nor interest, necessary to maintain their production. Contact with known downstream open source projects, and a message to users@ has not produced any concern. Jena has a process for retiring modules: delete in git, record the last git commit with the code in case some interest emerges and will maintain the module. ## Community Health: Activity seems normal. Some of the figures are slightly skewed because one PR had 48 commits which is unusual for Jena. The dev@ list is also the destination of JIRA email and is otherwise quite quiet. The speed of evolution of the project is down to developer time. The users@ is active and the main support channel.

Last addition was Greg Albiston on 2019-07-08. ## Project Activity: The project dealt with CVE-2021-33192. The project released 4.1.0 slightly earlier than the usual cycle bu this was timely for both addressing the CVE issue, where there isn't a simple works around in all cases, and also tiding-up after the 4.0.0 release. 4.0.0 had some low level changes that were not completely transparent to user applications. The move to requiring Java11 has been smooth. ## Community Health: Activity on mailing list and PRs have been quieter. There is no obvious specific reason for this. Given the major version change reported last report, "quiet" is probably a good thing with a slight reduction in open JIRA tickets.

Last addition was Greg Albiston on 2019-07-08. ## Project Activity: Jena 4.0.0 was released on 2021-04-01. This release marks moving from requiring a Java8 platform to requiring a Java11 platform. After discussion in the dev and users communities, the feeling was that this was a moment for a major version jump. Because of this, there was as much removal of deprecated and old code as time permitted. The release was roughly inline with the "release every 3 or 4 months" ideal that the project has. The release date was by-chance! This release also contained an updated implementation of "RDF-star" - an emerging new feature for RDF that is gaining traction. This release passes all the syntax and evaluation test suites. ## Community Health: The community, as seen on the user list and via contributors remains healthy. The thread on whether to update to Java11 was the busiest user list thread.

Last addition was Greg Albiston on 2019-07-08. ## Project Activity: Jena release version 3.17.0 in December. This incorporated many dependency updates promoted by enabling the github dependency bot on the project codebase. Jena usually does a release every 3-4 months. This release was at just over the 4 month mark from the previous release. The project is engaged in moving from a Java8 to Java11 as a prerequisite. We see some dependencies and potential interesting dependencies requiring Java11. ## Community Health: The project channels remain at normal level; there was a burst of process email connected with the upgrade of dependencies. Last report activity level were down, which as noted, coincided with northern hemisphere summer.

Last addition was Greg Albiston on 2019-07-08. ## Project Activity: Jena usually does a release every 3-4 months. As noted last report, 3.15.0 has a problem with one of the server binaries, and new users have ran into problems. The project released 3.16.0 with a fix in July; user email and StackOverflow questions about the issue have dropped off. ## Community Health: The original Jena project (pre-ASF) celebrated the 20th anniversary of the first code release! The first public release of code was 28th August 2000. We held a community event online, kindly hosted by the Lotico meetup, to mark the occasion. Claude Warren (PMC) organised a successful Jena track at ApacheCon with talks about Jena itself and from project using Jena. While the statistics show a reduction in activity and emails, a dip in the northern hemisphere summer is not unusual. The number of outstanding JIRA has increased slightly, by about 5 tickets.

This release has introduced a problem with one of the server binaries, and new users have run into problems as witnessed by StackOverflow and users@ messages. The project is starting a new release rather than wait for usual 3-4 months between releases. ## Community Health: Overall community health is good with normal levels of email on users@, JIRA tickets, GitHub PRs and StackOverflow questions. Of note, is a report from a user that they had loaded 12billion triples (a WikiData dataset) into a Jena TDB database. This is the largest publicly reported load for Jena. Query performance was reported to be satisfactory.

Last addition was Greg Albiston on 2019-07-08. ## Project Activity: This quarter has been busier than last on github, JIRA and mailing lists. JIRA reports are coming in faster than being addressed but this happens. Some are showing deep understanding of the codebase. The project has been receiving more PRs, with an increased in the number of contributors. With the help of Roy Lenferink, the production of the Apache Jena website has moved from using svn and Apache's custom CMS to being stored in git and using Hugo. A big clear-out of log4j1 use finally completed. ## Community Health: Generally more active this quarter though last quarter include Xmas and New Year. Splitting out github PR emails to a separate list helped dev@ but that was still busier than last quarter. JIRA activity: 67 issues opened (+63%), 54 closed (+38%) Github: 12 code contributors (+71%) 58 PRs opened (+28%), 55 PRs closed (+19%)

The project operates aspires to a releases every 3-4 months and is now discussing the 3.14.0 this month, subject to PMC availability. The 3.14.0 has several contributions from new people, outside the main committers. The project is also discussing reorganising its mailing lists to reduce the volume on dev@ by moving github traffic to a separate list. The hope is that with less low-level emails and pull request specific emails, it will encourage discussion on the longer term direction of Jena. ## Community Health: Activity on the users@ and dev@ lists is about normal. The new people contributing pull request is encouraging and hopefully some these people will remain going forward. We expect a drop in dev@ email when the github traffic is directed to another list. email: dev@jena.apache.org same level: (566 compared to 562) users@jena.apache.org same label (291 emails compared to 292) JIRA: 44 issues opened in JIRA, past quarter (12% increase) 39 issues closed in JIRA, past quarter (18% increase) Github: 49 PRs opened on GitHub, past quarter (36% increase) 46 PRs closed

Last addition was Aaron Coburn on 2019-01-22. - Greg Albiston was added as committer on 2019-07-08 ## Project Activity: Jena 3.13.0 was released on 2019-09-28. Jena 3.13.0 was released on 2019-10-11. The 3.13.0 release had some minor issues and the project has corrected these with 3 .13.1. ## Community Health: The 3.13.0 release was 4 months after the previous one. The project aims for 3-4 months so this was at the longer end. The 3-4 month is clock-tick is aspiration rather than resourced plan. The project mailing lists are at normal levels, and users@ is getting some more answers to questions from other users, not just the main developers. StackOverflow is the main place for basic questions.
## Description:
Jena is a framework for developing Semantic Web and Linked Data applications
in Java. It provides implementation of W3C standards for RDF and SPARQL.
## Issues:
There are no issues requiring board attention at this time"
## Activity:
The project added a major new component to provide GeoSPARQL, an OGC standard
for geospatial query of RDF data in SPARQL. Because this large contribution
needed time and effort to integrate, a regular release (3.11.0) was done to be
followed by a release for GeoSPARQL (3.12.0).
## Health report:
The project dev@ list is at normal levels of activity, the users list on the
quieter side though stackoverflow continues to have more user questions than
users@ - and more people answering users questions.

## Description: Jena is a framework for developing Semantic Web and Linked Data applications in Java. It provides implementation of W3C standards for RDF and SPARQL. ## Issues: There are no issues requiring board attention at this time. ## Activity: The project has continued to evolve the codebase. It is still in the process of incorporating the significant contribution of a GeoSPARQL implementation, mainly restricted by PMC members' bandwidth. Elsewhere, a new contribution of metrics support for the Jena Fuseki, triplestore protocol engine, has been received and the project is working with the contributor to incorporate that. Discussion of release 3.11.0 has started. ## Health report: The project is at normal levels of activity, with JIRA and git pull requests getting being responded to, and the users list remains active. ## PMC changes: - Currently 14 PMC members. - Aaron Coburn was added to the PMC on Tue Jan 22 2019 ## Committer base changes: - Currently 17 committers. - No new committers added in the last 3 months - Last committer addition was Aaron Coburn at Mon Jun 18 2018 ## Releases: - Last release was 3.10.0 on Sun Dec 30 2018 ## JIRA activity: - 45 JIRA tickets created in the last 3 months - 31 JIRA tickets closed/resolved in the last 3 months
## Description: Jena is a framework for developing Semantic Web and Linked Data applications in Java. It provides implementation of W3C standards for RDF and SPARQL. ## Issues: There are no issues requiring board attention at this time. ## Activity: The project has just voted for a release 3.10.0 in line with the 3-4 month cycle (as and when volunteer time is available). The git repo has been migrated seamlessly to gitbox - an excellent process by INFRA. The project has received a significant contribution of a GeoSPARQL implementation and the team is migrating from the custom spatial query solution to the Open Geospatial Consortium standards-based one. The project is also retiring some unused modules that do not receive attention and have had very little in the way of user questions over the last few years. EMail to the users list to alert users of the intention has not received any push-back for the first group of modules to be retired. ## Health report: The project is at normal levels of activity, with JIRA and git pull requests getting being responded to, and the users list remains active. There are also many questions asked and answered on stackoverflow where answers come from a wider community. ## PMC changes: - Currently 13 PMC members. - No new PMC members added in the last 3 months - Last PMC addition was Chris Tomlinson on Sun Apr 29 2018 ## Committer base changes: - Currently 17 committers. - No new committers added in the last 3 months - Last committer addition was Aaron Coburn at Mon Jun 18 2018 ## Releases: - 3.10.0 was released on Sun Dec 30 2018 ## JIRA activity: - 44 JIRA tickets created in the last 3 months - 58 JIRA tickets closed/resolved in the last 3 months

## Issues:
There are no issues requiring board attention at this time
## Activity:
Activity remains mostly normal across mailing lists and GitHub. There was a
large dip in traffic to the Users list this quarter (down 50%) which appears
to be due to new features having bedded in.
Previous quarters user traffic was spiked due to the introduction of the new
TDB2 component and extended discussions around a hard to reproduce concurrency
bug in a long standing component. The project does also experience periodic
spikes in traffic caused by university professors mandating use of Jena for
courseworks and these users are often complete novices who generate temporary
high volumes of traffic. We did experience a lot of that last quarter while
this quarter has been much quieter in this regard.
The project has made a couple of releases and incorporated several large
contributions from new contributors who have been made committers. A
committer was also promoted to the PMC in recognition of their ongoing
contributions to the project.

## Description:
Jena is a framework for developing Semantic Web and Linked Data applications
in Java. It provides implementation of W3C standards for RDF and SPARQL.
## Issues:
There are no issues requiring board attention at this time.
## Activity:
There have been two releases this quarter.
## Response to previous board comment:
> Comments:
> mt: It has been a while since a new committer or PMC member was
> added. Is the PMC tracking any prospects?
mt, thank you for the question.
Yes, it has been about 18 months since the last PMC member was voted in and
about 15 months since the last committer was added.
The PMC is active and gets 3 or more binding votes on the hoped-for quarterly
releases. Occasionally, people outside the PMC give feedback on the release
artifacts.
No one on the PMC is employed to work on Jena; some do put in a few
work-hours. Much of the Jena codebase is stable and "maintenance".
There are also some active contributors outside the PMC/committer base. These
people tend to focus on a specific area of the codebase and they may provide a
short burst of interaction to see through their own contribution.
We are discussing how to help sustain this engagement and translate it into
some project level interactions. We have some people on the radar and we are
discussing how to get them involved outside of their specific contribution.
## Health report:
Project activity has been significantly higher than the long-term average
because of the two releases have been done this quarter. The major new feature
in 3.5.0 needed settling into the release process. However, there was also a
bug in an unrelated area which new users could easily walk into, so the
project made another release earlier than the usual 3-4 month cycle. In
addition, there has been ongoing development including contributions from
outside the committers.
## PMC changes:
- Currently 12 PMC members.
- No new PMC members added in the last 3 months

## Releases:
- Jena 3.5.0 was released on Mon Oct 30 2017
- Jena 3.6.0 was released on Sun Dec 17 2017
## Mailing list activity:
Two releases in one quarter significantly increased the dev@ mailing list
activity.
The 3.5.0 release included new database subsystem which generated quite a lot
of user@ discussion, including long threads on benchmarking of all storage
options.
- users@jena.apache.org:
- 625 subscribers (up 8 in the last 3 months):
- 952 emails sent to list (378 in previous quarter)

## Description: Jena is a framework for developing Semantic Web and Linked Data applications in Java. It provides implementation of W3C standards for RDF and SPARQL. ## Issues: There are no issues requiring board attention at this time. ## Activity: Jena released version 3.4.0 2017-07-17 The project has received a software contribution of a new storage subsystem. Software grants from the main developer (who is also a committer but this work was not done at Apache) and his employer, for most of the development period, have been obtained. This work was originally funded by a UK government R&D grant, with the condition the work was open source. ## Health report: The activity levels look normal. ## PMC changes: - Currently 12 PMC members. - No new PMC members added in the last 3 months - Last PMC addition was Adam Soroka on Mon Jun 06 2016 ## Committer base changes: - Currently 15 committers. - No new committers added in the last 3 months - Last committer addition was Lorenz Buehmann at Fri Oct 28 2016 ## Releases: - Last release was 3.4.0 on 2017-07-17 ## JIRA activity: - 29 JIRA tickets created in the last 3 months - 30 JIRA tickets closed/resolved in the last 3 months
## Description: Jena is a framework for developing Semantic Web and Linked Data applications in Java. It provides implementation of W3C standards for RDF and SPARQL. ## Issues: There are no issues requiring board attention at this time. ## Activity: Jena 3.3.0 was released 2017-May-2017, roughly in-line with the desired increased release cadence. The project has received external contributions, including a significant one that extends support for Lucene text analyzers. In addition, existing some committers have worked closely together on language-sensitive collation while maintaining compatibility with the W3C standard and existing releases. ## Health report: The development activity for the project is at normal levels. The slight drop on the users list may be due to a small number of users asking large numbers of basic questions on long threads. This has caused some push back by other users on the list which the PMC has noted. The project has before gone through such cycles before. We can hope that any users put off by the perceived noise will become active again. ## PMC changes: - Currently 12 PMC members. - No new PMC members added in the last 3 months - Last PMC addition was Adam Soroka on Mon Jun 06 2016 ## Committer base changes: - Currently 15 committers. - No new committers added in the last 3 months - Last committer addition was Lorenz Buehmann at Fri Oct 28 2016 ## Releases: - Last release was Jena 3.3.0 on 2017-May-2017. ## Mailing list activity: - users@jena.apache.org: - 628 subscribers (up 4 in the last 3 months): - 637 emails sent to list (846 in previous quarter) - dev@jena.apache.org: - 150 subscribers (up 0 in the last 3 months): - 1239 emails sent to list (1315 in previous quarter) ## JIRA activity: - 55 JIRA tickets created in the last 3 months - 64 JIRA tickets closed/resolved in the last 3 months
## Description: Jena is a framework for developing Semantic Web and Linked Data applications in Java. It provides implementation of W3C standards for RDF and SPARQL. ## Issues: There are no issues requiring board attention at this time ## Activity: The project released 3.2.0 in February this year which was a faster release cadence than usual. This release contained some new APIs and our usual slew of bug and performance fixes. There have been ongoing efforts involving both existing committers and community contributions towards bringing our secondary text indexing components up-to-date with the current versions of the Apache Lucene libraries and we hope to be able to release that to users soon. In addition, the unmaintained Solr text indexing backend is being replaced by a new Elasticsearch backend. ## Health report: The project has discussed how the slow ~6 monthly release cycle has been creating problems for users because releases often contain a lot of change, some of which may be subtle e.g. corner case behavioural fixes, that create issues when users upgrade. This is particularly noticeable when users who build products on top of Jena and have their own release cycles jump multiple versions in a single upgrade. Also, when we introduce bugs/regressions the long release cycle means it takes a long time to get fixes into the hands of users for those who aren’t prepared to use development snapshots. The project is hoping to release more frequently this year to help mitigate this problem since we believe that more frequent releases will limit the amount of change in each release and make upgrades less painful. The topic of maintaining multiple branches i.e. Multiple stable release branches was discussed again but as in the past the consensus was that the active contributor base is insufficient to support this. ## PMC changes: - Currently 12 PMC members. - No new PMC members added in the last 3 months - Last PMC addition was Adam Soroka on Mon Jun 06 2016 ## Committer base changes: - Currently 15 committers. - No new committers added in the last 3 months - Last committer addition was Lorenz Buehmann at Fri Oct 28 2016 ## Releases: - Fuseki 2.5.0 was released on Tue Feb 07 2017 - Jena 3.2.0 was released on Tue Feb 07 2017 ## Mailing list activity: Developer list traffic has seen a spike during March 2017 due to a large pull request from a new contributor which was related to the aforementioned Elasticsearch text indexing backend. This has generated lots of automated notifications to the list in the form of both JIRA and GitHub comment mirroring. The GitHub code review feature in particular, tends to generate large amounts of notification messages. ## JIRA activity: Normal levels
## Description: Jena is a framework for developing Semantic Web and Linked Data applications in Java. It provides implementation of W3C standards for RDF and SPARQL. ## Issues: There are no issues requiring board attention at this time. ## Activity: The project released 3.1.1 on the usual 6 month-ish cycle. This has been the regular project tick for the last couple of years but the feeling is now that Jena is putting too much into a release and that a 3 month cycle would be better. Several major new contributions are in progress. On the users list, there has been a lot of student-level questions, particularly of the nature "ask-before-try", leading to some pushback. After a discussion on dev@, the consensus is that this level of questions is something that wil happen from time-to-time and unless it is damaging, the core user community accepts it. The PMC added Lorenz Buehmann as a committer in recognition of the effort he provides in patiently answering many questions on users@. StackOverflow continues to be a second source of user questions. ## Health report: The level of activity is normal; a slight lull for December and post-release is not uncommon. ## PMC changes: - Currently 12 PMC members. - No new PMC members added in the last 3 months - Last PMC addition was Adam Soroka on Mon Jun 06 2016 ## Committer base changes: - Currently 15 committers. - Lorenz Buehmann was added as a committer on Fri Oct 28 2016 ## Releases: - 3.1.1 was released on Tue Nov 08 2016 ## Mailing list activity: Normal levels. ## JIRA activity: Normal Levels - 33 JIRA tickets created in the last 3 months - 37 JIRA tickets closed/resolved in the last 3 months
## Description:
Jena is a framework for developing Semantic Web and Linked Data
applications in Java. It provides implementation of W3C standards for
RDF and SPARQL.
## Issues:
There are no issues requiring board attention at this time.
## Activity:
The project has been proceeding steadily. Initial thoughts on the
next release have lead to an uptick in activity.
## Health report:
The project has been running as normal and there have been some
nice contributions from outside the usual contributors.
## PMC changes:
- Currently 12 PMC members.
- No new PMC members added in the last 3 months

The project mailing lists are at normal levels - a wave of
students asking beginner questions on users@ have got some
very patient answers from the community. Discussions on
github reflected to dev@ account for the slight peaks
recently.

## Description:
Jena is a framework for developing Semantic Web and Linked Data
applications in Java. It provides implementation of W3C standards for RDF and SPARQL.
## Issues:
There are no issues requiring board attention at this time.
## Activity:
The project has had a routine quarter after the release of Jena 3.1.0 in May.
The amount of activity is highly dependent on contributor time.
(There are no directly salaried developers.)
## Health report:
The drop in dev@ email can be attributed to the fact the release
happened at the beginning of the reporting period. The last cycle was
busier because of getting the release together and issues coming out of
the woodwork followed by a quiet period.

## Description:
A framework for developing Semantic Web and Linked Data applications
in Java.
## Activity:
The major release mentioned in the last report happened at the end of
July. This release included a number of incompatible changes including
making all java packages come under org.apache.jena, migrating to Java8,
and requiring persistent data to be reloaded.
Such changes have the potential for a lot of users@ email but this time, so
far, only a small number of migration questions have been raised.
Ongoing development of Jena includes development of a major new component
for an in-memory storage sub-system. This is being developed via
discussions on the dev@ list.
## Health report:
Activity is at around its normal levels, with September on the users list
being towards the upper end of "normal" and dev list being a little less
busy. Given a recent release, this is normal. Issues on JIRA continue at
a steady rate.

The dev community has decided to roll this into the main release process, while it does not block a release, to reduce overhead. While it still has users, none have come forward to actively maintain it so it remains "at risk" of being moved to a separate area and not released any more.

The last release managed to get the necessary 3 +1's but the module receives very little in the way of contributions from the whole community. The committers (who don't use it) have kept it working as the main codebase changes. The current plan is to include in the main release on a maintenance basis on the understanding that any architectural changes to the main system may cause it to be dropped unless active contributors emerge.

Apache Jena is a Java framework for building Semantic Web applications based on W3C and community standards. There are no issues to raise with the board. Releases: * After community testing on a variety of SQL databases setups, Jena SDB 1.3.5 was release in 10/Oct. This completes the release of all storage components after incubator. * A full release of Jena 2.7.4 and Jena Fuseki 0.2.5 was made on 24/Oct. Community and activity: users@ had 150-300 messages a month, and dev@ had 180-500 messages a month. The next released planned is Jena 2.10 - a jump in version number to sync internal versions, and to move a simplified system, removing little and unused features for better maintainability and extension. Standards: Apache Jena was referenced on the implementation reports for various SPARQL specifications as they progressed to recommendation status.
Apache Jena is a Java framework for building Semantic Web applications based on W3C and community standards. Jena became a TLP April 2012. Issues: There are no issues to raise with the board. Community and activity: Releases - Jena 2.7.3 Community: The project also asked for community testing of the SDB component - this runs over various SQL databases and testing by the committers is impractical. The community feedback has been very good and the project has decided to keep the code alive and release it formally. users@ and dev@ mailing lists had approximately 180 and 200 messages respectively and almost all messages on the user list have had some kind of response, whether from the user community itself or specifically from committers. Standards: Apache Jena passes the full query, update and protocol test suite for the upcoming SPARQL recommendations now the W3C process has approved final drafts.

Status: The project is executing the graduation process. The administrative updates have been done and the infrastructure setup completed. The project is running on migrated infrastructure with some minor points arising and being addressed. Many thanks to infra for the migration work, including the help getting the project demo site, sparql.org up and running on an Apache zone. Community: users and dev mailing list had approximately 200 message each. In addition, there is a steady flow of questions on http://answers.semanticweb.com/ (a stackoverflow-like site). Activity: A release vote has been called for the first TLP release.
Apache Jena is a Java framework for building Semantic Web applications based on W3C and community standards. Jena became a TLP April 2012. Status: The project is executing the graduation process. The administrative updates have been done, the infrastructure setup started for the transfer of resources (lists, website, svn) and the project is now engaged in the transfer tasks. The final piece of non-Apache project infrastructure is the demo site sparql.org. This is in the process of migrating to an Apache hosted zone as time permits. Community: In April, the user list had 293 message and the dev list 156. The project has completely migrated from lists used before Apache; messages to old lists receive pointers to the Apache lists. JIRA is active as a means of reporting issues and requesting features. Some contributions have been received. One, from SAP, may require a software grant; further clarification of the size of the contribution has been sought. Releases: The project's main incubator release was in December; additional components were released in February, March and April. Issues: There are no board issues.

Jena is a semantic web framework in Java that implements the key W3C recommendations for the core semantic web technologies of RDF and SPARQL. Jena entered incubation in November 2010. The project is discussing graduation. Progress since the last report: - The project has voted for a new committer and IPMC member for the project. This is the second person since the start of incubation. - The project has successfully produced a release. The first incubator release included the system core and query engine, which is 80% of the codebase but not all the modules. TDB is in active development and is only now ready for release. - Redirections placed at both old websites to point to the Apache incubator website for Apache Jena. - About 20 JIRA items have been resolved since the last report. - Users email traffic on old, non-Apache lists continues to decline. Issues for the Incubator PMC or ASF Board: None. Plan: - Graduation preparation (checking, drafting the scope/charter, resolution, chair, more checking) - There are no technical or infrastructure items blocking graduation. - Releases of further subsystems: TDB, Fuseki, LARQ.

Jena is a semantic web framework in Java that implements the key W3C recommendations for the core semantic web technologies of RDF and SPARQL. Jena entered incubation in November 2010. Progress since the last report: The project has voted and accepted a new committer onto the project. The necessary ICLA has been completed and the new committer is now active. The project has completed code clean-up, contacting previous contributors and asking them to re-contributed to the Apache project. One contribution from a company that no longer exists remains under a BSD-style license and is noted in the codebase. The Apache-hosted website has been built using Apache CMS and buildbot system. A first release is active, while a second release with all the previous existing documentation ported to the new system is underway. Important issues to address for graduation: * Do a full release. * Continue to grow the community. Issues for the Incubator PMC or ASF Board: None. Technical development: The new transactional native SPARQL storage systems has been moved to the development trunk. Leading-edge users users continue to test this with us. About 50 JIRA items have been resolved since the last report.

Jena is a semantic web framework in Java that implements the key W3C recommendations for the core semantic web technologies of RDF and SPARQL. Jena entered incubation in November 2010. Progress since the last report: The project uses the Apache-based developer list exclusively and is now encouraging users to use the Apache-hosted user mailing list by regular reminder and an automatically added a trailer on all messages on the old user list. The Apache-hosted website is "under construction" in staging. The project selected the Apache CMS and buildbot system. The design and navigation is done. Next step is to populate the website with the content from the old sites. One module, LARQ, is being used to learn about the Apache release process and the requirements it brings with it. Important issues to address for graduation: * Create a code base in Apache with legal clearance. There are about 10 small contributions (a few line upto a single class file) across the whole codebase that that need to be resolved. All are currently covered by BSD licences. * Do a full release Issues for the Incubator PMC or ASF Board: None. Technical development: The new transactional native SPARQL storage systems, TxTDB has been advertised as a prototype snapshot. Some users have offered to help with testing.
Jena was accepted into the Apache Incubator November 2010. It is an existing project migrating to ASF. It has a large codebase that provides a semantic web framework in Java that implements the key W3C recommendations for the core semantic web technologies of RDF and SPARQL. Three most important issues to address for graduation: * Create a code base in Apache with legal clearance. * Establish the Apache-based community for developers, contributors and users * Create and communicate open project processes aligned to Apache Issues for the Incubator PMC or ASF Board: None. Community development: We have started to advertise the existence of Apache-hosted mailing lists. Traffic on these lists continues to grow. A new work area on enhancing the native storage system with transaction support is being conducted in public on Apache cwiki and mailing lists. Project development: We have received the software grant from HP; HP has copyright on the majority of the codebase. We can now migrate the code to Apache infrastructure, and contact previous contributors for the remaining areas (these are small in number and scope).

Traffic on these lists has started to grow. We are now using JIRA alongside our old issue tracker while we migrate across. Project development: Project infrastructure is now set up and tested. The last planned, non-Apache release, was done for Jena and all the related sub-projects. This will minimise disturbance to users during code migration. Code migration to Apache SVN will begin when a software grant for the majority of the codebase is received (from HP). We understand that HP is actively working on this.
Description: Jena was accepted into the Apache Incubator November 2010 (http://mail-archives.apache.org/mod_mbox/incubator-general/201011.mbox/%3C4 CEC31E4.9080401@apache.org%3E). It is an existing project migrating to ASF. It has a large codebase that provides a semantic web framework in Java that implements the key W3C recommendations for the core semantic web technologies of RDF and SPARQL. Three most important issues to address for graduation: * Create a code base in Apache with legal clearance. * Establish the Apache-based community for developers, contributors and users * Create and communicate open project processes aligned to Apache Issues for the Incubator PMC or ASF Board: None. Community development: We have let our existing communities know that the project is moving from being an independent project to one based in ASF. Project development: The first step for the project is get the incubator infrastructure up and running, including ICLAs and user accounts. The project plans to make one last, non-Apache release to give it some space to setup in Apache with minimal disturbance to users.
