This document provides a tutorial on the CMDI metadata standard and the ISOcat Data Category Registry. It discusses ISOcat's role as a registry for linguistic data categories, how data categories provide semantics for CMDI metadata elements and components, and how they are referenced in CMDI. It also provides an overview of the status and standardization process of the CMDI metadata profile.

9. Status of the metadata profileInitial set of data categories has been created (to never disappear) by the Athens Core groupBut your own components might need your own specific DCsTranslations for many EU languages have been addedNo ISO Standardization yetTDG is working towards starting up the processAthens Core group will become more prominentThe addition of container DCs to be linked to CMD components is planned17 January /20119CMDI tutorial
