[jira] [Commented] (JENA-656) Doesn't send all accepted mime types in header

["Rob Vesse (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JENA-656?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13939130#comment-13939130 ] 

Rob Vesse commented on JENA-656:
--------------------------------

More general headers sent by badly behaving/configured servers like {{application/json}} and {{application/xml}} are already handled internally.  The problem is we don't want to encourage bad behaviour so either we don't send them like we do currently or we should send them with low quality factors e.g.

{noformat}
application/sparql-results+xml,application/xml;q=0.1
{noformat}

> The Jena HTTP query engine doesn't send all the mime types it can process in the accept header. It would be better if it could send all of them, so services can send a better response.
> Currently the HTTP-Accept-Header claims that jena can only accept "application/sparql-results+xml" resp. "application/rdf+xml" as query result. In fact it can process much more types.
> Furthermore some services [1] will return a more general content-type in the header when answering a request (e.g. "application/json" instead of "application/sparql-results+xml" or "application/xml" instead of "application/rdf+xml"). It would be good to also try to parse such results and to see if the content can be interpreted as SPARQL result.
