It also does the translations in both directions, of course.

Yes, quite. We have used this technique successfully in several projects at IHMC, and it was the basis for the successful Darpa RKF system built a few years ago at SRI (which used an interface based on CMapTools.) Constructing informal (but well-constructed) Cmaps turns out to be one the most effective techniques for 'knowledge extraction' from domain experts. There are number of publications on the general topic downloadable from http://cmap.ihmc.us/Publications/

BTW, ironically, COE will 'translate' any content it does not recognize in any Cmap into plain RDF triples, which is technically legal RDF, though it may not capture the intentions of the Cmap authors, of course.
