Dear We are developing OGSA-DAI RDF handling activities and we want some users who can use or evaluate our software. Our RDF handling activities supports SPARQL query language and basic ontology APIs. Supported platform is Jena and Sesame. 1) For those who just want to use the software, we set up the demo server environment(OGSA-DAI 2.1) also with some example perform documents. If you already have OGSA-DAI, you can use our server with these perform documents. For mover details, please visit http://www.dbgrid.org/ -> OGSA-DAI-RDF 2) Our software, V0.2 is also available, however, this software is premature version and we are now completely re-designing to synchronize with the coming discussion of GGF WS-DAI for RDF(S) specification. If you can evaluate our alpha software, please download the package and give us some feedback to enhance the next version of the software and the coming specification of WS-DAI for RDF(S) query interface. For DAIS for RDF activities, we will soon make an announce to invite to join this activity. Also, we have upgraded our OGSA-WebDB software which will be announced later.
