Hi Alexander, I would like to add to the important answers, precisions, considerations from Mark...
RDF support is not so much about what you store than about what you can ingest and about what services you have to offer on the (LinkedData) Web. RDF is modelling information in triplets (information "atoms". One can outline the difference with TopicMaps which are modelling using "molecules") and, like a database, RDF can represent anything. Vice versa: any existing database like DSpace can be showed as a huge pile of RDF statements. The central use of RDF is to allow "mashing" statements from different sources using URI as identifiers for merging. So, what is important is the semantic, what you do with the information. Also one must not mix the tool (DSpace) and the data it can store, index, retrieve: you could make an RDF Data repository in DSpace by just adding RDF in the format registry, storing RDF files as bitstreams and by adding some publishing functions. Mark is presenting many interesting initiatives in different directions. We integrated SKOS (from sources in RDF, XML, SQL, CSV, Java Bundles...) in DSpace for http://www.windmusic.org The problem was much more what we do with the SKOS statements (indexation, cataloguing, search, item displays, result sort, etc.) and not so much how do we store them. A separate Tomcat application (ASKOSI) is used to display and manage SKOS records. Now we are looking for help to create (or reuse) an application to manage RDF statements writing by a community: Maintaining thesauri and their interrelations requires: - a user interface for browsing/search/visualisation of concepts and their relations, - a workflow manager to record update proposals and have the maintainers vote about them. We would like to "make happen" such a "maintenance workflow manager for RDF and SKOS" first to serve the needs of Belgium Poison Centre (*) and then those of the DSpace/SKOS/RDF Community in general. Please click below for draft specifications: http://www.askosi.org/maintenance.pdf We would be very happy to collaborate with an existing project. Please let me know your potential interest for your students, for your project team or for yourself. Wishing you a very nice day, Christophe Dupriez (*) The resulting thesauri are currently used to index and retrieve within a DSpace Repository of 90 thousands scientific articles about Acute Toxicology. ------------------------------------------------------------------------------ Beautiful is writing same markup.
