Parsing prefixes

[TimMeuser]

Hi,
I have two questions:

1. What is the best way to parse SPARQL query prefixes, like PREFIX ex: http://example.org/ ?
2. Is there a definition of the used rdf4j grammar?

Thanks in advance,
Tim

Hi Tim,

could you tell us a bit more what you want to achieve ? E.g do you want to write a SPARQL parser yourself, or just turning namespace prefixes into namespaces URI ?

Best regards

Bart
