GraphFilter/Condition on postAnnotation method

[Adeurien]

When using the POST service of the Annostore, using the defined ontologies for tasks 2.5 and 3.4, the posted graph is filtered with the relation :
(null, RDF.Type, ANNOTATION_TYPE).

This filter causes the loss of all the information linked to the annotation. Moreover, the condition :
if (typeTriples.hasNext()) {
final Response.ResponseBuilder rb = Response.status(Status.BAD_REQUEST);
rb.entity("Graph contains more than one annotation");
throw new WebApplicationException(rb.build());
}

... seems to be a problem, since for each annotation we have several triples to insert.

I think that both the filter and the raised exception on the above condition should be removed.

Best,
Adrien
