    128 ==== Mapping from ISO to RDFS/OWL ====
    129 
    130 This mapping duplicates much of the XML hierarchy already present in ISO19115/19139 by creating new elements that are often almost the same as those being mapped. Given that RDF already includes dublin core elements, why can't we simply embed the ISO19115/19139 elements into RDF? This would be a big win if we could do this as we already have services to manage ISO objects (eg. editor can add objects to a metadata record, directory interface in admin manages directories of metadata objects (or fragments)).

    152148Speed 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

    154 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).
