Hi Everyone,

I am on of the developers at the Swiss Institute of Bioinformatics for
uniprot.org. We have for a while now a sparql endpoint in beta.
beta.sparql.uniprot.org. I am trying to generate a Service Description
for that endpoint that is as useful as possible and I have some

The first questions is about the uri of a named graph in an endpoint.
Taking the following extracted example. I have a named graph in the
Is it correct to use the same uri for both the concept of the named
graph and the name of the named graph?

@prefix : <http://www.w3.org/ns/sparql-service-description#>
@prefix void: <http://rdfs.org/ns/void#> .

    :graph <#_3> .
    :name <http://purl.uniprot.org/tissues/> .

    void:classes "1" ;
    void:distinctObjects "3560" ;
    void:distinctSubjects "1872" ;
    void:triples "6108"^^<http://www.w3.org/2001/XMLSchema#long> ;
    a :Graph ;
    :name <http://purl.uniprot.org/tissues/> .

Or should the first part be

    :graph <#_3> .
    :name <http://purl.uniprot.org/tissues/> .

I also have a question about declaring the entailment regime. If no
reasoning was applied, should an entailment regime be declared? if yes
which one?
If only owl:sameAs reasoning as done by OWLIM is used which entailment
regime URI should I use?

The last question is: in the attached example files, which properties
are you missing i.e. you think would generally be useful?
