[Wikidata-bugs] [Maniphest] T339347: qlever dblp endpoint for wikidata federated query nomination

Hannah_Bast added a comment. @dcausse I am confused, where does https://data.nlg.gr/sparql come from? I thought the endpoint in question were https://qlever.cs.uni-freiburg.de/api/dblp and https://qlever.cs.uni-freiburg.de/api/wikidata, where the following command lines work just fine:

[Wikidata-bugs] [Maniphest] T339347: qlever dblp endpoint for wikidata federated query nomination

dcausse added a comment. Note that even if we changed blazegraph to accept multiple formats for all endpoints by setting the header that you suggest (`Accept: application/sparql-results+xml, application/sparql-results+json`) the https://data.nlg.gr/sparql endpoint still produces an http 500

[Wikidata-bugs] [Maniphest] T339347: qlever dblp endpoint for wikidata federated query nomination

dcausse added a comment. @Hannah_Bast Blazegraph does properly send the header `Accept: application/sparql-results+xml` but it seems that this endpoint does only work when requesting `application/sparql-results+json`, anything else produces an http 500 error: curl -k -XPOST

Gehel added a subscriber: dcausse. Gehel added a comment. @Hannah_Bast: anything is possible :) That being said, that's not a feature that is possible out of the box. It would require some customization on our side to be able to configure different HTTP headers for different federation

[Wikidata-bugs] [Maniphest] T339347: qlever dblp endpoint for wikidata federated query nomination

Hannah_Bast added a comment. Is it possible to configure Blazegraph to send the following Accept header: Accept: application/sparql-results+xml, application/sparql-results+json That would ask for results in SPARQL XML format (like before), and as a fallback in SPARQL JSON format.
