Work-instance and isDerivativeOf

Dear all,

Following the discussion we had today on the work-instance relationship [1] and the proposal to label it with something like "derivative", I copy below some definition bits for the property isDerivativeOf from the Europeana Data Model [2].
Not that I want to push it by all means. Maybe you'll want a different definition. As long as it works... But I don't see why I'd conceal it, if there's something to be re-used instead of this group working hard to re-invent his own words.

I'm going to ask the people in the task force I've mentioned if they can send museum or archive examples using this property.

Best,

Antoine

==========

Definition: "This property [...] relates a resource to another one, obtained by reworking, reducing, expanding, parts or the whole contents of the former, and possibly adding some minor parts. Versions have an even narrower meaning, in that it requires common identity between the related resources. Translations, summaries, abstractions etc. do not qualify as versions, but do qualify as derivatives."

Obligation & Occurrence: A resource may be a derivative of to 0 to many resources. Conversely, a resource may have 0 to many resources that are derivative of its.

Example: The Italian translation of Moby Dick is a derivation of the original work.

Rationale: This property enables associating resources that are one the derivation of the other. This is required since Europeana may collect descriptions about resources and their derivations. It also supports browsing of resources by derivation. Finally, it allows the integration of all properties used in content providers' descriptions that capture the notion of derivation in the sense outlined above, such as those capturing versioning, translations and abstractions. To this end, any such properties should be declared to be a (direct or indirect) sub-property of edm:isDerivativeOf.
