2014 The RDF Data Cube Vocabulary W3C Recommendation 16 January 2014 http://www.w3.org/TR/vocab-data-cube/

Notes:

• some key concepts "inherited" from SDMX are not fully re-explained in the RDF Data Cube specification (e.g. the concept of a dimension) - the authors assumed that readers have a previous knowledge of "SDMX" as a recommended best practices (read the 2009 SDMX User guide and Guidelines for DSDs)
• relationship between QB and SCOVO / SDMX vocabularies used in the example - the reader should know that it is not required to learn the scovo bits (which are only here to explain how the working group got there): SCOVO is an earlier attempt to convert SDMX into a RDF vocabulary http://vocab.deri.ie/scovo
• the reader should also know that the use of SDMX vocabularies is optional
