Dear Silvia, all,

Thanks for bringing this to our attention.

OK, here is a quick comparison between the TT elements and our current draft:

- ttm:title: maps to a ma:title instance without qualification, i.e. is more general

- ttm:desc: 1:1 mapping to ma:description

- ttm:copyright: 1:1 mapping to ma:copyright

- ttm:agent: maps to ma:creator or ma:contributor, there are qualifiers (person, character, group, organization, other) that specify the type of agent rather than the role in the creation process

The following two elements are used as subelements of ttm:agent:

-- ttm:name: maps to the content of ma:creator/ma:contributor, similar to the structured/unstructured return values of our API there are qualifiers for specific name parts or for an unstructured string

-- ttm:actor: links a character to a real-world agent

To conclude: Most of the ttm elements are covered in our draft, some are more general, but in general mapping seems to be feasible. We could propose to rename "desc" to "description", as (i) it is the only abbreviated name and (ii) then all elements that map nicely to ma elements would have the same names. The only element that is different is the agent element, which not only includes creators and contributors, but also fictional characters. While ttm lacks a way to express the role in contribution, ma lacks a way to express the character impersonated by an actor. Attempting to harmonize this could improve both vocabularies.

Best regards,
Werner
