New Release: v5.0.5

OpenLink Software is pleased to announce a new release of Virtuoso, Open-Source Edition, version 5.0.5.

The previous release, 5.0.4, was short-lived due to a problem in SPARQL-to-SQL code-generation, so this announcement addresses the new features introduced over and above version 5.0.3:

In the core Database Engine:
Added the LUBM benchmark for RDF data managers to testsuite; a check for backup/restore status; optimizations and an inxop option for bitmap indexes.

In the areas of RDF and SPARQL:
Support for xsl:float; Sponger cartridges for SVG, XBRL and HR-XML documents; URL-rewrite rules for XBRL; additional SPARQL engine optimizations.

In the ODS Applications Suite:
New support for Meaning of a Tag (MOAT); Support for Identity and Authentications standards such as OpenID 2.0 and OAuth; additional ODS generated de-referencable URIs; enhanced Wiki search; improvements to Calendar.

Additionally, there are the following bug-fixes:
In the core database:
Problems with FTP server and HTTP headers; saved unnecessary seeks in bitmap checks; fixed the 64-bit range of IRI and row IDs; various minor bug-fixes and compiler-warnings.

In the ODS Applications Suite:
Fixed ATOM protocol upstreaming, Creole markup, docbook and invalid HTML generation in ODS-Wiki; improvements to SIOC based RDF instance data in relation to ODS-Calendar todo-lists; a new UI for system navigation.
