DoJo (builds on Jena) <no URL available> > > => (DSpace) offline investigation > => (DSpace, der) dialogue re: storage APIs, requirements for > schema support We (aidministrator) are currently developing an RDF/RDFS repository and query engine called "Sesame" for the European IST-project OnToKnowledge (www.ontoknowledge.org). Sesame is written in Java and currently uses (but is not limited to) PostgreSQL for persistent storage. Sesame currently has a query engine using a language based on ICS-Forth's RQL. There are some differences between Sesame and RDFSuite: Sesame does not yet support all of RQL's primitives, but it does support properties with multiple domain- and range-restrictions or properties without any domain- or range-restrictions. More information can be found at our demo server at http://sesame.aidministrator.nl/ . We can create a DSpace account on this server if people are interested in using it on DSpace data. Just let me know.
