Adding explicit data source provenance in RDF

[SvenLieber]

Currently the RDF representation of each data source is stored in a separate named graph, for example <http://kbr-syracuse> for KBR translations, <http://master-data> for countries, taxonomies etc. or <http://isni-sru> for RDF generated from the ISNI SRU API.

Where this data comes from and what its license is, is currently not explicitly represented. However, such provenance information may be added in the form of RDF, for example

@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix dc: <http://purl.org/dc/terms/> .
@prefix void: <http://rdfs.org/ns/void#> .
@prefix cc: <http://creativecommons.org/ns#> .
