Hey everyone,
Happy to hear that Wiktionary will make it into Wikidata. Looks like a long but promising way to go. I just happened to edit Wikidata items about dictionary types as part of my work on taxonomy extraction (see presentation http://dx.doi.org/10.5281/zenodo.61767, paper http://ceur-ws.org/Vol-1676/paper2.pdf, and tool https://www.npmjs.com/package/wikidata-taxonomy). The current state of dictionary types and instances in Wikidata is given below, created with "wdtaxonomy Q23622" on the command line.
I welcome everbody familiar with and/or interested in lexicography to improve this classification (there is no WikiProject lexicography yet). One problem of Wiktionary is that it tries to subsume all kinds of dictionaries, making it less practical for specific use cases. I bet that Wiktionary data in Wikidata will allow to extract special kinds of dictionaries by selection of Wikidata properties and queries some day in the future. Before this I hope that we also have some better understanding of dictionary types.
Cheers Jakob
