Happy New Year, everyone! I received the email below from the semantic grid list. I haven't explored the S-MDS package beyond reading the documentation on their webpage, but it looks both interesting and relevant to GLUE. At the abstract level, this package provides a "semantically" queryable access (i.e., a SPARQL end-point) to some instance data. The instance data is maintained by querying WSRF Resource Properties (RPs). An overview is available here: http://pages.dbgrid.org/s-mds/dist/doc/background/architecture.htm [in the diagram, they show RPs as local to the target system. I guess this is a deployment decision, so might not be a requirement] If this package were extended to expose GLUE data, then one could also use the same SPARQL end-point to query GLUE metadata. An alternative approach would be to define an WSRF-RP binding for GLUE. I've skimmed through the WSRF-RP spec (v1.2 draft-4) and, given a suitable GLUE/XML binding, this doesn't look too hard: a simple encapsulation through a suitable GLUE XML-namespace should work. The S-MDS package has an "RP/ontology mapping algorithm" that (I believe) automatically converts the WSRF-RP into some OWL ontology description of the WSRF-RP. Provided this mapping algorithm works for GLUE/WSRF-RP (i.e., GLUE/XML encapsulated within WSRF-RP SOAP), this should "just work" :-) This would be an interesting extension of the current work on an XML binding. Apart from the application within MDS, we might get an RDF/OWL binding for free! Cheers, Paul. ---------- Forwarded Message ---------- Subject: [SEM-GRD] A new software release: Semantic MDS TP1 Date: Sunday 23 December 2007 From: "Said Mirza" <mirza@ni.aist.go.jp> To: gt-user@globus.org, sem-grd@gridforum.org Hi, We are pleased to announce the release of our new software Semantic MDS (S-MDS) TP1. S-MDS is a Semantic Metadata Discovery and Monitoring system implemented on the top of the Globus Toolkit 4 (GT4). It is an information system that uses semantic web technologies to semantically describe grid resources (services) so that they can be more efficiently and effectively discovered and monitored. The software does not require any change to the (targeted/monitored) grid resources so that it can "peacefully" work with your grid resources. S-MDS harvests many semantic web technologies but it does not require users to be familiar with the technologies. It provides the following management and query tools for supporting the users. * S-MDS wizard and tools for easy creating, enriching and registering the semantic metadata. * A GUI-based query client for easy constructing a (SPARQL) query. This tool also includes a monitoring client that periodically pulls data from the repository and presents the data in a graphical view.
