namedGraphToModel

public static org.apache.jena.rdf.model.Model namedGraphToModel(java.lang.String graphName,
                                                                de.uni_koblenz.aggrimm.icp.crypto.sign.graph.GraphCollection gc)
                                                         throws java.lang.Exception

Converts Signingframework's NamedGraph into Jena's Model. It is required, that GraphCollection stores the prefixes (if present), but that they are not applied (i.e. its applyPrefixes() method should not be called). Otherwise there could be errors when converting, since Signingframework when applying prefixes just looks whether the resource uri starts with that prefix uri, which would be true in both cases below:

Throws:

java.lang.Exception

modelToGraphCollection

public static de.uni_koblenz.aggrimm.icp.crypto.sign.graph.GraphCollection modelToGraphCollection(java.lang.String modelURI,
                                                                                                  org.apache.jena.query.Dataset modelDataset)

Converts Jena's Model into Signingframework's NamedGraph of GraphCollection. Resulting GraphCollection contains exactly one NamedGraph that corresponds to the provided Model (modelURI) from the provided Dataset. The resulting GraphCollection stores the prefixes (if were present in the Datastore), but they are not applied (for reasons, see namedGraphToModel() doc).
