Attach a piece of metadata to a resource. The changes are recorded in a ModelChanges object to later be committed into the main model. A side effect of the metadata serialisation is to set the date.

Assumes a read or write lock has been obtained for the model before calling.

Parameters:

changes - The running record of triples to add or remove

attachedTo - The resource the metadata should be attached to.

newMetadata - The metadata item to be attached

Returns:

the RDFNode where the new metadata is stored

Throws:

com.hp.hpl.jena.rdf.model.RDFException

StoreException
