Glad to see Wikidata and Commons coming together first on December 2 and then in January/February, and thanks for this great office hour record of a collaborative conversation among Wikidatans and structured data folks - https://meta.m.wikimedia.org/wiki/IRC_office_hours/Office_hours_2014-11-20 - and also to see that structured multimedia data is up next. :)
Cheers, Scott
