Re: AW: Annotation body a transcription of the target

Hi Rainer,

That's a tricky question: I guess it depends whether you still consider whether something that is typed as pelagios:Toponym is still a 'simple' body. One could argue it is becoming a semantic tag, sort of.

I'm afraid I can't really tell. And in fact since I was among the ones not in favor of using resources for simple string bodies anyway, I guess it's more appropriate for me not to try it ;-)

cheers,

Antoine

It doesn't look crucial (unless a same annotation will handle different places at once, which doesn't seem a good thing to do) but *if* you need it, then you'd have two basic choices

To keep annotations coherent (cases without transcription vs. cases with transcription) I'd like to add the transcription as a separate, second body (which should be fine, I guess?).
