Dear all, It is with great pleasure that we are finally able to announce the release of Sesame 1.1. Sesame 1.1 is a stable, high-capacity, flexible framework for storing, querying, and manipulating RDF and RDF Schema. Its main features include: - Runs on any Java 1.4 enabled platform. - Multiple backends: in-memory, RDBMS (MySQL, PostgreSQL, Oracle), native disk-based storage. - Highly scalable. - SeRQL query and transformation language. - RQL and RDQL query languages. - Rio RDF parser: fast parsing and writing of RDF/XML, N-Triples, Turtle and N3. - Stable high level access APIs allows easy, flexible integration in existing projects. - Flexible connectivity through direct Java access, RMI, or HTTP. - Inferencing support for RDF and RDFS semantics. - Easy to use Web interface. - Customizable inferencer for domain-specific entailments. - Ontology Management Module: - change tracking - fine-grained security Highlights of release 1.1: - The Graph API, an extension of Sesame's access APIs, allows fine-grained manipulation of RDF models directly from Java. - The Native Disk Store is a new storage backend that works directly on the file system, without need for a DBMS. It uses B-Tree indexing on binary files for fast, efficient and scalable storage. - SeRQL revision 1.1 is a syntax revision that makes SeRQL queries even easier to read and write, and makes embedding in XML easier. - Blank node handling has dramatically improved compared to 1.0.x. - Lots of issues related to full Unicode support have been fixed. - RDF Schema inferencing has been updated to be fully compliant with the W3C RDF Semantics Recommendation. - Support for MS SQL Server as storage backend RDBMS. Thanks to Adam Skutt for providing fixes and suggestions for this. - The Rio parser now supports the Turtle serialization format. - Partial OWL reasoning support through Sesame's custom inferencer. - Fully updated and extended User Documentation, including code examples for use of the Sesame APIs and a new Troubleshooting chapter. A long list describing the bug fixes and improvements can be found in the ChangeLog, or in Sesame's issue tracker: http://www.openrdf.org/issues/secure/BrowseProject.jspa?id=10000&report=changelog Please check out the upgrade documentation in doc/upgrade.txt before upgrading an existing Sesame installation.
