    6161Speed of RDF triple stores versus Lucene? Free text search in Apache JENA RDF triple store/sparql queries is supported by using Lucene to help - see LARQ sub-project: http://jena.apache.org/documentation/larq/index.html

    63 Spatial searching: At present we can do mixed spatial and textual searches for OGC CSW support by filtering Lucene searches with query results from spatial database. How would this work in SPARQL? OGC GeoSPARQL would be 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).
