We are pleased to announce the release of Apache Jena 3.5.0.
== Key features of the release
Introducing TDB2:
http://jena.apache.org/documentation/tdb2/
*TDB2 is not compatible with TDB1*
Compared to TDB1:
* No size limits on transactions : bulk uploads into a live Fuseki
can be 100's of millions of triples.
* Models and Graphs can be passed across transactions
* No queue of delayed updates, no transaction backlog problems.
* "Writer pays" - readers don't
All work for update is done on the writer thread.
* Datatypes of numerics preserved; xsd:doubles supported.
TDB2 is subject to change.
We solicit any and all feedback (good and bad!) about TDB2 to help
advance it to deployment-ready.
JENA-1390 : Add StmtIterator.toModel :
JENA-1392 : Add dynamic dataset support to SDB.
JENA-1395 : "--output RDF/XML" now prints using the basic block-oriented
writer, which uses less memory. Use "--formatted" (same as "--pretty")
for pretty printed RDF/XML.
JENA-1398 :
Upgrade FOAF to add new spelling and deprecation of old for archaic FOAF
properties
