I have worked on Commons a bit and was already thinking how could
Wikidata be integrated into it.

I don't think category links would any longer be represented in
wikitext, but each image description page would be a wikidata item.
Wikidata already has various de facto "statement groups" (I'm sorry I'm
not up to the newest terminology so I'm not sure how are they called).
The data in the groups are edited independently of each other, and also
displayed in various ways. Right now, there are two groups: labels and
wikilinks. Labels are displayed as article titles and only one label is
displayed at the time, while wikilinks are displayed in a table and
multiple wikilinks are displayed at once.
But there is no need to stick to this organization, and various wikis in
various namespaces could have different statement groups that could be
displayed in various ways. For example, it would be possible that, on
Commons, in Image namespace, have three groups: image description, image
properties, and image categories. Image description would be displayed
and edited similar to Wikidata label: only in the current interface
language. Image properties would be displayed and edited as wikidata
properties will be. Image categories would be displayed and edited as
categories.
Image metadata might tie into all of this as well: these would be
special properties that are not directly editable but filled in on image
upload.
* what about subcategorizing? How does this work?
Similarly, every category would be an item. Category titles in various
languages would be handled exactly the same as Wikidata labels. A
category would have its supercategories as properties.
About the only potential problem that I see is that in some cases
categorization is made logically, and in some cases linguistically. For
example, on Commons, [[:Category:Tree rings]] is a subcategory of
[[:Category:Rings]] which makes sense in English language, but in
Serbian language tree rings aren't called tree rings and no one would
ever got the idea to categorize them as such or to search for them in
that category.
* is it only about categories? What about image descriptions?
Multilingual image descriptions are a common occurence.
* what about the plenty of data that is already in Commons? Can this be
reused or replaced?
A lot of data in Commons is already very structured, so I believe it
shouldn't be a problem to transfer it to another format. About the only
problem that I see is the potential need for coexistence of raw wikitext
and wikidata in the same namespace while the transition is occuring, but
even that is solvable.
