Hi all, I wrote a toy, sample application of mappings, see http://www.w3.org/People/fsasaki/annotation-mappings/ It takes as an input currently MediaRSS and Goggle video site maps and allows to query them on a metalevel. See as example inputs http://www.w3.org/People/fsasaki/annotation-mappings/01/videositemap.xml http://www.w3.org/People/fsasaki/annotation-mappings/01/top_rated.rss mappings are definded for "assumed" properties title, description, pubdate, tags, thumbnail, player. Some thoughts: - I think we should not deal with the problem of getting the metadata out of an object but leave that to a low level API. In the case of the above formats it was just an XML parser, but it could be anything else, e.g. an XMP reader. - (Known) isuses arise if we have different data types for the same property, e.g. for pubdate in the above two cases. - Other issues arise with repition of values, see e.g. the "tags "property, though that might be a subproblem of the data type issue. Looking forward for comments, Felix
