The name spaces for the enconding of CIDOC CRM in RDF & OWL
Versioning Mechanism
http://www.cidoc-crm.org/cidoc-crm/ and http://erlangen-crm.org/current/ follow the same mechanism already
Versioned namespace (e.g. http://erlangen-crm.org/150716/) is mainly for users who want to be able to track which version of the document they used at a certain point in time (e.g. in order to track how concepts were described in old versions)
There is no such mechanism for the rdf
Suggestion: Synchronisation via equivalence on the ontological layer for the two above
