Hi Malte,
sorry for not responding earlier.
I see multi-linguality as a cross-cutting concern which is quite challenging.
But I think DM's particular "semantic" data model (composites of typed
topics/associations) and the REST concept (one resource, multi representations)
leads us the way. I would see e.g. "Köln" and "Cologne" as 2 *representations*
of the *same* topic. That is a topic of type "City" which carries the semantics
of "Germany's fourth-largest city".
DM could store the several translations of a topic in the topic's properties
and the topic value would always reflect the translation that matches the
request's Accept-Language header.
This should not be too difficult to implement in the DM core, or even as a DM
plugin.
3 advantages of this approach:
- No explosion of complexity (API, storage, performance).
- No proliferation of the DB (and possibly the user interface!) with
redundant ("un-semantic") topics.
- Maintaining the topic's relationships remains a manageable task (e.g. Karl
moves from Cologne to Berlin).
Cheers,
Jörg
