It would be possible to add a method with a default implementation to
GraphLike - then look to see if this can be more efficient for
RDF4J (e.g. avoiding the multiple connections)
I don't think this would break compatibility unless someone had
already implemented addAll on a subclass, with a different signature.

[RDF] adding Quads - Bulk

[Fred Hauschel]

Hi there,

it looks like I am bound to the interface 
org.apache.commons.rdf.api.GraphLike#add. And in the RDF4J 
implementation, a new connection to the repository is established for 
each quad/triple. This is not very useful.
Am I missing another possibility or am I the first to have a problem 
with this ?


Is there a reason, why there is no Method like GraphLike#add(List 
statements); ?


Thanks Fredy

[RDF] New Jena Version

[Fred Hauschel]

Hi there,
i think I would like to use commons-rdf, but not with the old Jena 
version. So here is a PR for a new version. I have no idea about osgi 
and jena doesn't seem to support it anymore. so I just used the non osgi 
dependency.
