Are there cases for skos:Concepts linked by owl:sameAs to non-GND, non-VIAF resources? #94

The current DM2E->EDM algorithm directly links to contextual resources that reference GND or VIAF URIs via owl:sameAs. If a skos:Concept has owl:sameAs statements that point to neither GND nor VIAF, we need to change the owl:sameAs to skos:exactMatch to be compatible with Europeana's usage of SKOS.

This is implemented but I could not find any data to test. If any data provider has data like this:

... dc:subject <http://.../concept1> .
<http://.../concept1> a skos:Concept ;
    owl:sameAs <http://not.viaf.and.not.gnd.de/concept/foobar> ;
    skos:prefLabel "Foo Bar" .

Then please add a comment with a reference to the containing aggregation so we can test this.

Here's one: http://data.dm2e.eu/data/html/concept/mpiwg/authority_lcsh/sh2008107595 in http://data.dm2e.eu/data/item/mpiwg/rara/MPIWG_S9DE5TWC

My mapping uses skos:exactMatch instead of owl:sameAs in skos:Concept but I think there is no real life example in the current data. It might be in GEI.

No occurence, corrected anyway...
