April 1st Fun with PROV, Dublin Core and some Others




2014, three months passed, and it looks like I have not started the blog yet. I guess a simple and short writing with a figure and a table could be a good start.

The figure is a mapping summary based on two W3C documents: Dublin Core to PROV Mapping (W3C Working Group Note 30 April 2013) and the direct mappings of Dublin Core to PROV mapping file.(URL: http://www.w3.org/ns/prov-dc-directmappings.ttl).


The table below is a brief view on W3C's task on Provenance Vocabulary Mappings (using SKOS mapping). This time, I only choose OPM, PREMIS, and Dubin Core, and use the direct mappings of Dublin Core to PROV mapping (owl:equivalentClass and rdfs:subPropertyOf) to relate PROV to DC.

It's interesting to see the difference of the event concept in these vocabularies. For me, the concept of event is supposed to be the first class of the provenance. The changing character of temporal and spatial components distinguishes provenance information from pure metadata description. However, in PROV we can only have the prov:InstantaneousEvent that is a non first-class notion, and this is probably because PROV has its original proto reference, OPM, that uses opm:Process as one notion of three opmo:Node class.
