Discover parameters used by SPARQL services that don't support SPARQL-FED What? Many public SPARQL endpoints are SPARQL-FED compliant, which makes use of SPARQL-FED unpredicatable.Why? A SPARQL endpoint mesh without SPARQL-FED support undermines the power of SPARQL in general i.e., the fact that its inherently distributed, unlike SQL.How? You can discover parameters used by SPARQL services that don't support SPARQL-FED, in regards to SPARQL query solution (results) publication, and then use them in SPARQL-FED. for example by executing the following query: SELECT DISTINCT ?EntityType WHERE { SERVICE <http://admin.numismatics.org/nomisma/query?output=xml> { SELECT * WHERE { ?Entity a ?EntityType } LIMIT 50 } } View the SPARQL Query Definition via SPARQL Protocol URL; View the SPARQL Query Results via SPARQL Protocol URL.
