Querying the SADI registry

[Tim Lebo]

sadi-dev,

I am trying to execute the following query against the SPARQL endpoint
behind http://sadiframework.org/registry/sparql/

select distinct ?service
where {
?service a <http://www.mygrid.org.uk/mygrid-moby-
service#serviceDescription>
}

Unfortunately, it defaults to HTML and ignores requests for the
standard format of "application/sparql-results+xml" [1]:

curl -H "Accept: application/sparql-results+xml" 'http://
sadiframework.org/registry/sparql/?query=select%20distinct%20%3Fservice
%0Awhere%20%7B%0A%20%20%3Fservice%20a%20%3Chttp%3A%2F
%2Fwww.mygrid.org.uk%2Fmygrid-moby-service%23serviceDescription%3E%0A
%7D%0A'

Do I need to do something extra to get standard SPARQL Protocol [2]
behavior?

Thank you for your consideration.

Regards,
Tim Lebo

I'll look into this today, but for now, you should be able to execute the query against the actual Virtuoso SPARQL endpoint, which is http://biordf.net/sparql — you will need to specify the named graph http://sadiframework.org/registry/ to avoid getting Biomoby services in with your results (so the query becomes:
SELECT DISTINCT ?service
FROM <http://sadiframework.org/registry/>
WHERE {
?service a <http://www.mygrid.org.uk/mygrid-moby-service#serviceDescription>
}
)

Cheers,

Luke

Luke,

Thanks for pointing me to the source endpoint. I can work from that,
though it'd be nice to have that exposed and/or having
sadiframework.org/registry/sparql/ behave like a normal endpoint.

Which is why I said "for now" and "I'll look into this today".

"http://sadiframework.org/registry/sparql/ should now be functioning as an
actual SPARQL endpoint. Let me know if there are still problems with it.
