Public Review of XKOS

The DDI Alliance <http://www.ddialliance.org/> is pleased to announce the
Public Review of XKOS, an RDF Vocabulary which extends the Simple Knowledge
Organization System (SKOS) for the needs of statistical classifications. It
does so in two main directions. First, it defines a number of terms that
enable the representation of statistical classifications with their
structure and textual properties, as well as the relations between
classifications. Second, it refines SKOS semantic properties to allow the
use of more specific relations between concepts. Those specific relations
can be used for the representation of classifications or for any other case
where SKOS is employed. XKOS adds the extensions that are desirable to meet
the requirements of the statistical community.

Links to the specification and instructions for comment are found at
http://www.ddialliance.org/Specification/RDF/XKOS.  We are eager to obtain
feedback from the DDI and RDF communities on this vocabulary. The comment
period is open until January 31, 2017, and we hope to hear from you.
