Dear OGSA-DAI and DAIS people, We are pleased to announce the release of the software called OGSA-DAI-RDF V1.0 The software is already released preliminarily as an alpha version and this is the first release which reflects the feedback. OGSA-DAI-RDF adds a new resource type "RDF" to the exisiting resource types such as "XML" and "relational" . The software provides a set of RDF processing OGSA-DAI activities which supports several RDF repositories like Jena. By using OGSA-DAI-RDF, you can combine your OGSA-DAI activities with our RDF processing activities such like SPARQL query processing and the reasoning functions of Jena. The improvements of this software include, 1) Re-designed activity interface. 2) New GUI including activity workflow editor 3) Introductions of product-independent RDF driver layer and drivers. If you interested in this software, please visit our site http://www.dbgrid.org/ and download the package by following the 'Download' link. One feature of our software is that this R&D is synchronized with OGF DAIS activity for RDF(S) specification. We are aiming to support the future OGF WS-DAI RDF(S) standards based on this software. We will have a discussion for WS-DAI RDF(S) topic within the DAIS-WG session in OGF20 at Manchester. The meeting is re-scheduled to 18:00 of Wednesday. If you also interested in this activity, please come to join the discussion. Sincerely, Isao Kojima, On behalf of the Data Grid Team Grid Technology Research Center, AIST Japan. Note: As you see, OGSA-DAI will soon release a new version 3.0 and our OGSA-DAI-RDF is based on OGSA-DAI 2.2. We will support the coming OGSA-DAI versions as possible; however, those who will plan to use OGSA-DAI 3.0 had better to use our software as beta software.
