I like this discussion because I learned a lot about rdf and the
application.
From the view of persistent identifier I would say a persistent
identifier needs a persistent object.
URIs and URLs are not persistent but what is the object behind it and
what are the metadata of the object?
The objects are the standard names for example air_temperature. If the
definition (not the description) was changed in a sense that the object
air_temperature changed we need a version.
But did this happen?
This is not a rhetorical question.
If not, we don't need a version of the standard name.
The metadata changed a lot. Having versions of the metadata is an other
question.
Best wishes
Heinke
