There is a CMAP plug in for Protege, it is map2owl. It does not translate, but instead it uses OWL constructs to represent the CMAP. 

 Having the cmap plug in into the protege environment makes it a lot easier for the "capture" and "formalization" processes to  be easily integrated. the cmap interface is very similar to the one provided by CMAP tools, it has almost the same features. When the information required has been captured, then it is very easy to "formalize" it. The map2owl plug in talks to the OWL plug in, this makes it possible to have the cmpa view and the OWL-plug in view synchronized. The direct manipulation interface provided also facilitates that domain experts work directly with the ontology without being aware of this. 

During the development of ontologies the knowledge elicitation is
facilitated by means of cmaps; one can also use other methods and
techniques, but from my experience CMAPS are quite useful, particularly
when developing ontologies -within the ontology community others have
other opinions about concept maps.

The url for the map2owl plug in is http://map2owl.sourceforge.net/  Please don't be afraid, I have not had any time to translate the web site in English, so for the moment the information in that url is in Spanish. But the plug in it self is in English. It does work with Protege 3.X not with P4 -not yet.

Alan Perlis once remarked that it is impossible to translate
an informal representation to a formal representation by
any formal algorithm.

Concept maps were originally designed as an informal notation
used in education.   COE implements a highly disciplined
(i.e., formalized) version of Cmaps that can be automatically
translated to OWL (a formally defined language).

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

On the other hand, informal Cmaps can be a useful intermediate
stage in a human-assisted translation to a more formal notation.

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.

Following is a talk that discusses the issues about relating
informal concept maps to Common Logic:

And following is another talk that discusses the use of
Common Logic in the medical domain:
