List of statements

 

Many FOAF files leverage other vocabulary such as
http://purl.org/dc/elements/1.1/, http://xmlns.com/wot/0.1/, etc.

 

Given a FOAF file, how to write SPARQL that can do the following?

 

1.      List all statements that use foaf vocabulary such as foaf:name,
foaf:mbox, etc?

2.      List all statements that do *not* use foaf vocabulary?

 

Thanks in advance for your help.

 

Best,
