There is a new version of SKOSEd for Protege 4.1 available on the
google code website
http://code.google.com/p/skoseditor/downloads/list. There are bound to
be some bugs, so post any problem to this list. This version still
treats SKOS labels as data properties, these need to be changed to
annotation properties and I will put some tooling in the next release
to help users update their SKOS files accordingly.
Cheers
