2008-03-28: Release v5.0.6

The bitmap-intersection join has been optimized so that it is now typically twice as efficient as an equivalent nested loop join. In some cases XML trees in the object position in RDF quads were incorrectly indexed, leading to failure to retrieve quads. There are improvements to locking, especially for concurrency of transactions with large shared lock sets, as is the case in the TPC-H queries. As part of the completion of our Business Intelligence extensions to SPARQL (SPARQL-BI), we released a sampling of TPC-H queries translated into SPARQL, and integrated this into the standard demonstration database. The new demo database provides a live sample of the TPC-H schema and instance data in linked data form, complete with SPARQL-BI variants of the standard TPC-H queries.

2008-03-07: New Whitepaper

We've written a new Whitepaper on TPC H As Linked Data.

2008-02-12: Release v5.0.5

This release includes the addition of LUBM benchmarks for RDF data-managers to the testsuite; a check for backup/restore status; optimizations to bitmap indexes. In the RDF/SPARQL field, there is support for xsl:float ; new Sponger cartridges for SVG, XBRL and HR-XML documents; URL-rewrite rules for XBRL and optimizations to the SPARQL engine. In the ODS Applications Suite there is new support for Meaning of a Tag (MOAT); support for OpenID 2.0 and OAuth; additional ODS-generated de-referencable URIs; an enhanced Wiki search facility and improvements to ODS Calendar.
