Not yet. We'll take care of informing all the interested parties & people
by using the relevant channels, as soon as we have something to share.

As I said in another thread [1], I would be good to check whether, besides
INSPIRE, we have other use cases motivating a more precise definition of
geographical names (and geometries) in the LOCN voc. And, in such a case,
it would be important to make such definitions interoperable with the most
used ways of representing such notions.
