controlled vocabulary for relational annotation

[eltonteb]

Just as it's now possible to import a controlled vocabulary in the normal annotation mode, it would be really useful to be able to do the same when in the relational annotation mode.

Agreed. Some pointers if someone wants to pick this up:

• the code where this is done for the "standard" tagging widget is here
• the place where this would need to be added for the relationship editor would be here

That's all old-school jQuery Javascript. Caveats:

• This feature is already available in RecogitoJS. However, since RecogitoJS is a modernized React rewrite, it's not possible to reuse that code in the old legacy Recogito codebase.
• In general, making this work is a bit tricker than just building the JavaScript frontend. Getting the tag vocabulary from the server into the browser page, having a UI component in the document settings where the user can upload/configure the vocab, etc. is another matter. This has been done before, for the "normal" tagging vocabulary, i.e. examples exist. It's just much more difficult to talk through, because it cuts across the whole backend/app/frontend stack. Therefore: if someone wants to take this on: do get in touch!
