Provide global ID resolver about dracor-api

[cmil]

The header would have to be Accept: application/rdf+xml, otherwise we'd redirect?

[ingoboerner]

I think so..

@lehkost what's the status on those IDs? As far as I can see, the TEIs don't have them yet.

Good question, theoretically there's nothing that would bar us from establishing global IDs now. Existing ID patterns (sub <publicationStmt) in Ger, Rus, Shake and Swe are as follows (always using random plays as example):

GER:
<idno type="DLINA-ID">174</idno>

RUS:
<idno type="RusDraCor">86</idno>

Shake:
<idno>Mac</idno>

SWE:
<idno type="Dramawebben">AgrellA_Ensam</idno>

So, Ger and Rus will be easy, they would translate to:
<idno type="DraCor">ger000174</idno>
<idno type="DraCor">rus000086</idno>

For Shake and Swe we would have to add numeric DraCor ID on top of their own ID (@mathias-goebel). They can be added as global DraCor IDs right from the start, whereas IDs for Ger and Rus have to be transformed into the new global pattern.
