Creating unique identifiers for EDM

+1 vote

Hi all,

I would like to mention some points about the identifiers used in EDM schema. These are:

  • the rdf:about of edm:providedCHO and rdf:resource of edm:aggregatedCHO should have the same value
  • the rdf:about of ore:Aggregation should have different value, defining a unique identifier (not just a number)
  • the rdf:about of edm:WebResource should have the same value of rdf:resource either of edm:isShownAt or edm:isShownBy.

In oder to create unique identifiers for ore:Aggregation, you could use the same url of edm:providedCHO or edm:aggregatedCHO, adding an extension like #aggregation to the identifer. For example, if you use the value "http://more.locloud.eu/object/DCU/1" on edm:providedCHO or edm:aggregatedCHO, you could use the value "http://more.locloud.eu/object/DCU/1#aggregation" on ore:Aggregation.
