In reading the recent
http://pro.europeana.eu/files/Europeana_Professional/Publications/Metadata%…
summary I think that some of the principles apply to Commons as well,
tohugh of course we're talking of very different beasts.
For instance:
* "Data should be enriched where possible (e.g. through multilinguality
or vocabularies)" is something we do better than most, even though
further integration with the Translate extension is needed;
* "using a preview portal as a means of data validation" is basically
covered by the CommonsMetadata tracking categories, also visible on
preview (though I don't know about GWT);
* "A thumbnail should be made available for all digital cultural
heritage objects" is easier for us but still a strength we tend to overlook.
Other ideas?
