This paper describes the efforts to marry LOD techniques to the needs of the international statistical community during two workshops on Semantic Statistics held at Schloß Dagstuhl, Leibniz Center for Informatics with the support of the GESIS Leibniz Institute for Social Sciences and the Data Documentation Initiative (DDI). Specifically, the authors address the extension of the Simple Knowledge Organization System (SKOS), an RDF vocabulary, to satisfy the requirements of classification systems and concept management for the statistical community. The paper is part of the Proceedings of the 59th World Statistics Congress of the International Statistical Institute, 2013, held in the Hague, Netherlands.
