> Reporter: Sarven Capadisli
> Assignee: Andy Seaborne
> Priority: Minor

> If I'm not mistaken, when */* content type is used in Accept header, content
> negotiation is incorrect. For curl -X GET
> http://sparql.org/books/sparql?query=SELECT+*+WHERE+%7B+%3Fs+%3Fp+%3Fo+%7D+LIMIT+1
> compare:
> {noformat}
> application/sparql-results+json =>
> application/sparql-results+json
> application/sparql-results+json;q=0.1 =>
> application/sparql-results+json
> */* =>
> application/sparql-results+json
> */*;q=0.1 =>
> application/sparql-results+json
> application/sparql-results+json;q=0.1, */*;q=0.9 =>
> application/sparql-results+json
> application/sparql-results+json;q=0.9, */*;q=0.1 => text/csv
> application/sparql-results+json;q=0.9, */*;q=0.9 => text/csv
> {noformat}
> It appears to be that, if the q-value of these two content-types are
> compared, the output content-type is incorrect.
> Here is an awkward one:
> {noformat}
> application/sparql-results+xml;q=0.1, */*;q=0.9 =>
> application/sparql-results+json
> application/sparql-results+xml;q=0.9, */*;q=0.1 =>
> application/sparql-results+json
> application/sparql-results+xml;q=0.9, */*;q=0.9 =>
> application/sparql-results+json
> {noformat}
> What's going on now?
> Just for completeness:
> {noformat}
> application/sparql-results+xml;q=0.1, application/sparql-results+json;q=0.9
> => application/sparql-results+json
> application/sparql-results+xml;q=0.9, application/sparql-results+json;q=0.1
> => application/sparql-results+xml
> application/sparql-results+xml;q=0.9, application/sparql-results+json;q=0.9
> => application/sparql-results+json
> {noformat}
> That looks okay.
