Releases: SDB 1.3.0 and TDB 0.8.1

New releases, compatible with Jena 2.6.0:

• SDB 1.3.0
• TDB 0.8.1

Both are avilable from the Jena development maven repository.

Note that TDB 0.8 is not compatible with TDB 0.7.X - there is a TDB 0.7.6 release that is the same as TDB 0.8.1 except it is compatible with all TDB 0.7 releases.

New releases: Jena 2.6.0 and ARQ 2.7.0

• Jena 2.6.0
• ARQ 2.7.0

These releases move Jena to using Java 5 and, in particular, Java generics, both internally and in the application APIs. We have also cleared out many deprecated features, switched to using SLF4J as the logging wrapper and reduced the number of jars by using features of Java 5.

There is also a RC release of TDB 0.8.0 which uses this upgraded Jena. Caveat: the file format for TDB 0.8 is different to that for TDB 0.7.x and earlier.

Release: TDB 0.7

• Download: TDB 0.7.1
• TDB Documentation

TDB 0.7 introduces new features:

• Named graph support - Native TDB support for RDF datasets
• Persistent RDF namespace prefixes
• Reification: Support for Reification style standard

The code is also available via maven and Apache ant/ivy:

Repository: http://jena.hpl.hp.com/repo-dev/
GroupId/Org: com.hp.hpl.jena
ArtifactId/Name: tdb

In addition, there has been significant internal changes to prepare for future work. Performance testing of the new architecture shows that when used the same way as 0.6, TDB performs at the same speed.

Named graphs are not as fast to load as the default graph in the dataset.

New release: SDB 1.2

• Download: SDB 1.2.0
• SDB Documentation

SDB 1.2 is primarily a maintenance release. It does include support for MS SQL Server 2008

There are no changes to the database schemas.

The code is also available via maven and Apache ant/ivy:

Repository: http://jena.hpl.hp.com/repo/
GroupId/Org: com.hp.hpl.jena
ArtifactId/Name: sdb

New Release: Eyeball 2.1

Chris has announced a new version of Eyeball. Eyeball is a tool for detecting problems with RDF data: misconstructed URIs, classes and properties with no definition, mis-spelled literals, etc. Eyeball is extensible: you can write your own Inspectors and have Eyeball apply them to your data.

Jena 2.5.7, ARQ 2.6.0

• Jena 2.5.7
• ARQ 2.6.0

This is a linked release - Jena 2.5.7 contains ARQ 2.6.,0 and ARQ 2.6.0 ships with the jars for Jena 2.5.7. The difference is mainly the source code included.

New Release: ARQ 2.5 and TDB 0.6

• ARQ 2.5
• TDB 0.6

This release of TDB introduces a statistics based optimizer for filtered basic graph patterns.

The release of ARQ is coupled with the release of TDB to provide enhanced integration into the query execution process for custom storage layers. It also provides any bug fixes done since the last release.

New releases: ARQ 2.4, Joseki 3.2, TDB 0.5

• ARQ 2.4
• TDB 0.5
• Joseki 3.2

The release of ARQ 2.4 introduces property paths. It also includes some internal simplification for making extensions to ARQ at the basic graph pattern level (a defined extension point for SPARQL) for different storage and logic engines. This simplified extension for basic graph pattern matching is used by TDB 0.5.

This is the first release for TDB. Documentation on the TDB wiki.

The release of Joseki 3.2 is an accumulation of many improvements since version 3.1. Some of these make the use of SDB and TDB with Joseki possible with the released version, not just with development CVS.
