POSTing a query

[lolive]

Hi.
I wish I could send my queries to the Osm-Planet endpoint via POST.
But it seems that this fails:
https://yasgui.triply.cc/#query=PREFIX%20osmkey%3A%20%3Chttps%3A%2F%2Fwww.openstreetmap.org%2Fwiki%2FKey%3A%3E%0APREFIX%20geo%3A%20%3Chttp%3A%2F%2Fwww.opengis.net%2Font%2Fgeosparql%23%3E%0ASELECT%20%3Fosm_id%20%3Fgeometry%20WHERE%20%7B%0A%20%20%3Fosm_id%20osmkey%3Abuilding%20%22university%22%20.%0A%20%20%3Fosm_id%20geo%3AhasGeometry%20%3Fgeometry%20.%0A%7D%20LIMIT%201000%0A&endpoint=https%3A%2F%2Fqlever.informatik.uni-freiburg.de%2Fapi%2Fosm-planet&requestMethod=POST&tabTitle=Query&headers=%7B%7D&contentTypeConstruct=application%2Fn-triples%2C*%2F*%3Bq%3D0.9&contentTypeSelect=application%2Fsparql-results%2Bjson%2C*%2F*%3Bq%3D0.9&outputFormat=table

If I switch the HTTP method to GET, things work fine:

Can the SPARQL endpoint support both GET and POST?

Thank you for that comment. A rewrite of the HTTP module is already on our TODO list (also to support Accept: headers and the like) and then we will also support POST.

In the meantime a question: Why do you prefer to send a POST request?

While developping Datao.net, I have had issues with big queries sent via GET on some endpoints. So it is sending them via POST.

Btw, does this statement imply that it is not possible to get results as RDF/XML at the moment?

We have rewritten the HTTP module in the meantime. Media types supported are: application/qlever-results+json, application/sparql-results+json, text/tab-separated-values, text/csv, text/turtle, application/octet-stream

POST is still not implemented, but on your list, see #615
