URI creation date
The date on which a URI annotated with this property was created.
This is the date that you created the URI that represents something, NOT the date that the thing referenced by the URI was created.
For example, if you create a URI on 2014-09-24 to represent a book published on 1982-10-17, then this annotation property should have the value 2014-09-24.
In other words, this annotation refers to the representation, not the represented thing.
For the 1982-10-17 date, we suggest the dc:created annotation.
