Unable to query local sparql endpoint from mediawiki

[amandine]

Hello,

We have a semantic mediawiki linked to a triple store (4store).
The data are mirrored into the triple store, we are able to query directly the triple store via the test query interface or via the sparql endpoint (http://localhost:8081/sparql/?query=select * where { ?s ?o ?p . }LIMIT 10).

But we cannot query the endpoint directly inside the mediawiki (via Linkedwiki template). It's like the endpoint is unreachable.


Do you know what could be the cause of the problem

Best regards
Amandine

For information
The code :

{{#sparql:
select ?s ?p ?o WHERE { ?s ?p ?o.} select * where { ?x ?y ?z . } LIMIT 10
|endpoint=http://localhost:8081/sparql/
}}

return

Error #sparql :Error query  : select ?s ?p ?o WHERE { ?s ?p ?o.} select * where { ?x ?y ?z . } LIMIT 10 Error endpoint: http://localhost:8081/sparql/ Error http_response_code: 400 Error message:

 -------------------------------------------------------------

the code :
{{#sparql:SELECT * WHERE { <PAGEIRI> ?o ?p.} }}

return an empty table

Whe have the same problem with the special page Special:Specialsparqlquery

 -------------------------------------------------------------

Installed version

And with the parameter debug=YES ?
Have you install curl for php5-curl ?

Hello,

php5-curl is installed

I don't know what is the debug parameter. An apache or a mediawiki parameter?

In the LocalSettings.php we have this following related debug parameters :
error_reporting( E_ALL );
ini_set( 'display_errors', 1 );

Best regards

Its a parameter of #sparql... |debug = YES

Try with a query on dbpedia. If it works, the problem is not in the wiki.

It's working with dbpedia.
Adding the parameter debug=Yes chage nothing. We have the same message.

It's strange that the problem is not the wiki, because the data are mirrored inside the triple store. That mean semantic mediawiki is enable to put data but not to retrive. How it is possible?

For information I check the stored URI and everything look good.

Sorry, I didn t see it.
You have a error in your query sparql in your first mail.
You have 2 times select.

Effectively sorry, me neither I didn't see it.

But the query  {{#sparql:SELECT * WHERE { <PAGEIRI> ?o ?p.} }}  doesn't not work too.

The version 2 of linkedwiki can work without semantic mediawiki. So, this query with pageiri can work only with the version 1.
This month, I have a few time to update linkedwiki but i dont know if pageiri is again possible with the new Smw.
