This surely is a valuable contribution.
However - I wonder if the 2004 SOAP API of SKOS is well aligned with 
current SemWeb.

Shouldn't it be RESTful to fit into e.g. LinkingOpenData?

See "How to publish Linked Data on the Web"

(which supports a SOAP API as well, and not even SKOS, but we'll be 
working on this)
