Hello!
I recently found your very interesting projects as I was looking for semantically rich dumps of Wiktionary, and I wanted to tell you about my use cases.
I work for the Semantic Web Company (we are also partners in the LOD2 project) and we have a term and phrase extractor, which we want to improve by enriching the extraction model with their various grammatical forms of the model's terms.
So additions we are most interested in are declinations, tenses and synonyms for German and English. Another use case would be to use Wiktionary data to suggest translations of controlled terms in a thesaurus. So the available translations would be great to have in RDF, too.
Best regards, Thomas
