Hello,
Vaidya et al. have published a paper about the work they did to extract content metadata from Commons description pages, using existing and new DBpedia tools. This could be of interest to this list as it relates to Structured data for Commons.

The paper is relatively short and reads easily. I've also written a review for the Signpost's latest "Recent research" report:
