Re: [topbraid-users] Problems submitting queries to the sparql-endpoint of a TBL EVN server from an external source.

[Scott Henninger]

Torbjørn; Please let us know the version and type of server you are using (OS, authentication setup, etc.)  Most importantly, let us know the specific error messages from the log, which is accessible through the TBL Logs page in the Server Administration page. One thing to note is that the SPARQL Endpoint, unlike TopBraid Composer and other services  such as SPIN Templates, does not know about prefixes.  So all prefixes, including owl:, etc. must be specified in a PREFIX statement in the query. The same goes for the default graph - either define in the SPARQL GRAPH statement or specify the default-graph-uri in the query string. Lastly, you can experiment with SPARQL Endpoint on your server by going to http://[host]:[port]/evn/tbl/query.  A UI is displayed that allows you to enter a query, choose the graph to execute it against, and choose the download format. -- Scott On 12/16/2014, 5:58 AM, Torbjørn Tessem wrote: Hi, I would like to submit queries to the Sparql-endpoint of my TBL EVN server from an external source. I have tried using queries based on the documentation found at http://download.topquadrant.com/evn/45doc/adminguide.html#evnendpoint. However, when I submit my query I only receive error messages, saying that it failed to retrieve query results and similar (depending on where i query from).    I suspect the problems may be related to authentication to the server. Is there a way I could include this in the sparql-queries? Or is there some way i can configure the Sparql end-point so that i could access it externally?
