[Semediawiki-user] [RDFIO] Querying the SPARQL enpoint externally

[Stephen H. <the...@gm...>]

I have been looking around online in various places, and have noted
that no documentation exists for POSTing a SPARQL query to an RDFIO
sparql endpoint on a SMW wiki from an external program.

It is mentioned on one website I saw that Bioclipse does this, and the
RDFIO source code hints at the ability, but it is not documented how
to do it. I would like to be able to make a SPARQL query against the
RDFIO Sparql Endpoing in my SMW Wiki via a remote HTTP POST.

I am wondering:
•	How would I HTTP POST the query? (What are the possible parameters)
•	What are the necessary parameters that need to be passed?
•	How does the endpoint expect the query to be formatted? (i.e. Just
as plaintext within a “query” parameter to the POST?)
•	How should I expect the results returned? (Can I pass a parameter to
get RDF/XML, or an XML result set returned just like in the special
page?)

Thanks,
Stephen
