Endpoint Demo for SPARQL endpoint description including RDFStats

in

Just finished the promised patch for Joseki, which integrates RDFStats and creates statistics for loaded datasets. I also finished the semwiq-endpoint package which is based on the patched Joseki. An endpoint is available at: http://ramses.faw.uni-linz.ac.at:8900/

It demonstrates:

  1. how voiD can be provided including the full route from robots.txt via sitemap.xml to the void:Dataset URI
  2. how RDFStats can be provided as part of voiD data (linked by SPARQL endpoint URI)
  3. SPARQL service and dataset description implemented for Jena ARQ/Joseki
  4. EXPLAIN query extension which outputs Jena ARQ query plans

The patch provides extended config parameters for Joseki configurations, here is an example service configuration:

<#service>
    rdf:type            joseki:Service ;
    joseki:serviceRef   "sparql" ;    # web.xml just route this name to Joseki
    joseki:voidInclude  [
        rdfs:comment "testing voidInclude"
        # these properties will be included in the void:Dataset
        # nested structures will be supported also          
    ] ;
    joseki:generateRDFStats "true"^^xsd:boolean ;
    joseki:dataset      swq:dataset ;
    joseki:processor    joseki:ProcessorSPARQL_FixedDS ;
    .

semwiq-endpoint and the patched Joseki 3 will be available in a few days on http://semwiq.sourceforge.net

good night ;-)
