redefine prefixes in sparql query produces error #25

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
When sending a query to callimachus' sparql endpoint that defines common 
prefixes such as RDFS, callimachus returns an error

org.openrdf.query.MalformedQueryException: Multiple prefix declarations for 
prefix 'rdfs'

It would be better to assume that the redefined predicate overrides the 
default, since (1) it is hard to know which prefixes are already defined (it 
seems for example that FOAF is not) and (2) eventually a user may want to 
redefine it un purpose.

Please provide a SPARQL query that produces this error.
