Release Notes: This version brings performance optimizations for the SQL and SPARQL engines and ODBC and JDBC drivers. New features include: an Excel MIME-type output option in the SPARQL endpoint; triple options bif:contains and transitivity; new RDF-generating cartridges with UMBEL lookups for the Sponger; support for very large HTTP client requests; a sparql-auth endpoint with digest authentication; and support for the Ubiquity Firefox plugin. There are also minor bugfixes for memory leaks, SPARQL "select distinct", and various SQL query syntax handling. XHTML validation is done in the ODS application suite.
Release Notes: This release includes new fully operational Native Graph Model Storage Providers for the Jena and Sesame Frameworks. It has better support for alternate RDF indexing schemes, parallelization of RDF sponger operations, new Sponger Cartridges, and inference engine optimizations for subclass and subproperty efficiently handling large taxonomies. Documentation: howto information on reading query plans, diagnosing SPARQL queries, and an updated RDF View example based on Northwind. Improved argument checking in built-in functions. Fixes for UTF-8 international character support in RDF, SQL, and SPARQL.
Release Notes: This version includes an enhanced cost-based optimizer; fixed-cost calculation for RDF inf nodes; improved SPARQL performance and support for BREAKUP optimization for triple-construction from SQL data and support for the LIMIT and OFFSET clauses to CONSTRUCT and DESCRIBE; documentation updates; significant updates to all ODS applications: compliance with the latest SIOC vocabulary, calendar, OpenID login and registration. There are also small bugfixes.
Release Notes: This version includes a major rewrite of the database engine, giving drastic speed improvements on both single- and multiple-CPU architectures, both to the SQL engine and RDF Views (SQL-RDF mapping). RDF support now includes middleware (called the Sponger) for transforming existing microformat, Web services, and XHTML data into RDF triples "on the fly". This release has full text indexing of literal objects in triple patterns, basic inferencing (subclass and subproperty support), SPARQL update language support and aggregate functions, and improved support for the XML Schema Type System (bif:xcontains).
Release Notes: An RDF Views language for mapping SQL to RDF on the fly. There are additional Triple Store APIs such as RDF NET and Semantic Bank (from MIT's SIMILE project), new Bitmap Index functionality, various performance enhancements in the area of SMP, and automatic background compaction for smaller relational or RDF databases. This release includes the OpenLink Data Spaces application suite with built-in support for SIOC, FOAF, AtomOWL, and SKOS ontologies, OpenID browser-based authentication, and other enhancements.
Release Notes: This version includes enhanced SPARQL constructions, significant improvements to SPARQL performance, as well as a new SPARQL demo based on the OpenLink AJAX Toolkit. It also provided more support and documentation for RDF functions and Web 2.0 technologies such as Atom, DAWG, GDATA, GeoURL, SIMILE, and SIOC. Additional hosting for PHP 5 was provided along with minor bugfixes for the Virtuoso server, ODS applications, and ODBC driver.
Release Notes: This release introduces OpenLink Data Spaces (ODS), a framework with several applications: Blog, Bookmarks, Briefcase, Community, Discussion, FeedManager, Gallery, WebMail, and Wiki. There are also bugfixes addressing network congestion, performance problems, a memory leak in free text indexing, operation with OpenSSL 0.9.8, and SPARQL access to DAV metadata. The RDF/XML parser performance has been enhanced, and support for MIME types in RDF has been added.
Release Notes: This release features runtime hosting for Mono, .NET (including ASP.NET), Java, PHP/Zend, Python, and Perl. It also added support for WS-Policy, WS-Security, WS-Routing, WS-ReliableMessaging, and WS-Addressing. A new BPEL Execution Engine was added along with XML document storage (with improved compression), SQLX Support for SQL/XML integration, a policy-based security model, SQL statistics-based cost optimization for the Virtual DB Engine, row level security, regular expressions for SQL DDL constraint definitions, triggers on views, and SyncML support for replication.
Release Notes: This release supports the Mono CLI, J2EE, ASP.NET (Mono version), Java Server Pages, PHP 4, SOAP 1.2, WSDL 1.1, WS-Security, XML For Analysis, XML Schema, and XQuery.
Release Notes: Web Services Platform functionality was added. This includes Exposure of SQL Stored Procedures and Java/C++ objects as SOAP-compliant Web services. Automatic Generation of Web Services Description Files (WSDL) is done for Web Services. UDDI Client and Server functionality was implemented.
