[Yanel-dev] Associate language versions

[Josias Thöny]

Hi all,

In order to build a navigation framework, we need a way to associate the 
different language versions of a page. I.e. for each language version of 
a page we need to know how to get the other language versions.

There seem to be the following three possibilities:

1. Links to language versions in meta data of each language version
e.g. meta data of search.html points to suche.html and vice versa (use 
uuids).
Problems:
- knowledge duplication
- when adding/removing a language version, the meta of all other 
versions has to be updated
- meta data not implemented yet

2. Common meta data with links to each language version
meta data refers to a common "language-cluster" meta data, which refers 
to all language versions.
Problems:
- extra meta file needed
- meta data not implemented yet

3. Sitetree
the sitetree refers to the different language versions of a node.
Problems:
- maybe language versions should be orthogonal to sitetree
- sitetree not really integrated yet (new pages are not automatically 
added to sitetree)

WDYT?

I don't know which option would be the best one. To me the lenya 
approach (tight coupling of language versions, encoding the language in 
the url) seems to be much easier to handle...
