Work on Jena3
Hi all,
Development has started on Jena3.
The main changes currently planned are:
* Package renaming
com.hp.hpl.jena => org.apache.jena
* RDF 1.1 Semantics for plain literals
Persistent data will need to be reloaded to be safe
* Java8 required
as well as cleaning up.
There is no fixed timescale for a release.
Soon, the development "master" will become this codebase.
There is a "jena2" branch in git.
There are draft migration notes:
http://jena.staging.apache.org/documentation/migrate_jena2_jena3.html
If you are interested in this work, please do drop into dev@jena.apache.org.

"master" is now switched over to Jena3 development.
There are snapshot builds.
http://repository.apache.org/content/groups/snapshots/org/apache/jena/
Conversion of applications is mostly
s/com.hp.hpl.jena/org.apache.jena/g
in code.
For assembler files, note class naming in ja:loadClass (e.g.
"com.hp.hpl.jena.tdb.TDB"). We are discussing putting some migration
support in for the latter.
URLs starting http://jena.hpl.hp.com/ are not changing.

Hi Fajar,
What gets done is what the community wants to do and resources. There
is no "must do" for Jena3, nor any "won't do". What gets done is what
people contribute.
It was said elsewhere that interacting with an open source project comes
down to one of 3 modes:
contribute / sponsor / hope
It would be great if some people collaborated to add OWL2 support,
either as an extension to the existing ontology API, a new one or rule
sets for various profiles of inference.
That development can happen separately as some kind of additional
developed separately and get contributed when done, or contributing work
to do into the main code base incrementally.
Anyone - drop over to dev@ and join in.
As a project, Jena has generally tended to emphasis long term stability
of users' investments. Jena3 is an opportunity to change more than
usual. There are many ways to add new features along side old ones so
that migration is smooth.

Hi Andy,
Is there no plan for OWL2 adoption yet in the near future?
Best regards,
