Dear Lydia,
Hmmm I have to confess I don't understand this completely and therefor can't give you an answer. Could you give me an example of what you are talking about and how you see Wikidata fit in?
Hmmmmmmm :-) I am somewhat at loss here. Let start from some basic, then.
1) is there a concise consensual definition of what Wikidata is expected to achieve?
2) Has this Wikidata project some Charter or terms of reference (TOR), or dedicated web site, you could give the URL? http://wikidata.org is redirected to http://en.wikipedia.org/wiki/Main_Page
3) Is there a list of the needs of wikimedia projects that wikidata is to address ?
4) What is/are going to be the language(s) of Wikidata?
5) What is the Wikidata's architectural framework? WDE (whole digital ecosystem)? Human communications? The Internet services? Users applications? Wikimedia?
6) What are the normative choices, strategic objectives and constraints imposed by the sponsors and the WMF?
7) How the Wikidata project is to liaise with its potential users' representatives (depending on the response to (5))
Thank you ! jfc
