[Nepomuk] semanticdesktop.org/ontologies/2007/08/15/nao vs semanticdesktop.org/ontologies/nao

[Roman Evstifeev]

Bangarang uses some nepomuk ontology namespaces without date (like
http://www.semanticdesktop.org/ontologies/nmm#musicAlbum), and some -
with date (like
http://www.semanticdesktop.org/ontologies/2007/08/15/nao#created)

What is the correct approach?

Aren't those namespaces gonna change their date part, when ontolgies
will be updated?
