Public Review of XKOS

The DDI Alliance 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 February 15, 2017, and we hope to hear from you.
