Here some old pointers to our TDWG - biodiversity - ViBRANT work from 2013:
creating this SMW wiki:
(with a SKOS vocab management system)
My own assessment: there are serious limitation in SMW, which can be worked with (e.g. we use an in-wiki xslt script to post-process), but having a more powerful system like wikidata would be most welcome.
However, to my present knowledge, the wikidata/wikibase based system would have to have a custom programmed user interface to make it usable, something the great semantic form extensions in SMW already make possible.
