SWAD-Europe Weblog Today I've been working on tidying the server side parts of the MEG Registry for educational metadata schemas. It is an RDF application both in the data model, client and server. The client is written in Java by Damian Steer and the server in Perl/C using Redland, by myself. The system is entirely based on the RDF graph model as well as using the rdf/xml format for interchange between the c-s, with a REST model for operations. See more at the MEG registry project web site with pointers to the sources (GPL or open source).
