In addition to SPARQL DROP, Marmotta partially also supports the SPARQL 1.1 Graph Store HTTP Protocol , so you could use the equivalent HTTP operation directly to the graph URI:

DELETE /context/default HTTP/1.1
Host: example.com

This is what the Context Manager at the Admin UI actually uses on "delete" context/graph.

It's here in the "SPARQ Update" spec rather than "SPARQL Query"

Apologies, I found my earlier issue in archive:

Drop default (sparql query)

Strange thing: “drop” is in the grammer -19.8 in  
(http://www.w3.org/TR/sparql11-query/ ), but I see no description of it…

Thx Michel

  <http://www.tno.nl/>
Can someone tell me how I can delete all triples from the default graph via the web 
interface? I know how to delete other contexts via the context 
tab.<http://www.tno.nl/>
I already tried:<http://www.tno.nl/>
Clear all etc. as query.<http://www.tno.nl/>
  <http://www.tno.nl/>
I had the issue before but could not find the solution anymore, something with a 
delete query…<http://www.tno.nl/>

Thx a lot, Michel<http://www.tno.nl/>
