 Spatial searching: At present we do mixed spatial and textual searches for OGC CSW query support by filtering Lucene searches with query results from spatial database via !GeoTools. How would this work in SPARQL? OGC GeoSPARQL would be part of the approach here I suppose: http://code.google.com/p/geospatialweb/ How mature is the GeoSPARQL implementation for Apache JENA or OpenRDF-sesame? (see links section: these projects don't look like they are mainstream parts of RDF frameworks yet?). Also, we use !GeoTools to parse the OGC filter language - how would this be converted to a GeoSPARQL query? (hmm).
 
-Relationship to DCAT proposal? This implementation already turns metadata records into RDF so that external semantic web/linked data services can obtain RDF from !GeoNetwork. Do we need more RDF?
+Relationship to DCAT proposal? This implementation already turns metadata records into RDF so that external semantic web/linked data services can obtain RDF from !GeoNetwork. Do we need more RDF? The answer here is that the DCAT proposal deals only with turning GeoNetwork records into RDF for external services, this proposal is about changing GeoNetwork's internal representation to RDF. The advantage of this proposal is that GeoNetwork will be able to integrate RDF facts from external sources into its internal representation eg. linking taxonomic concepts provided by an external RDF service.
