As far as I understand for DwC, in order to associate a dwc:Identification with a dwc:Occurrence we need to define a dwc:ResourceRelation analogous to http://rs.tdwg.org/ontology/voc/OccurrenceRecord#identifiedTo (The context is the building of examples of data annotations for the data extensions to the W3 incubation group document Annotation Ontology http://code.google.com/p/annotation-ontology/). The examples will be RDF). a. Am I right? b. Is there one already blessed by TAG? c. If b. is "No", does it make sense to put one on the table? -- Robert A.
