The WG feels that a split to produce Part 2 Edition 3 WD to harmonize with Part 3 Edition 3 is needed, adding more explanation for creating and using Classifications, and adding references in the Bibliography 11719-4 existing work on classifications.

Information technology — Business Operational View — Part 4: Information technology — Procedures for achieving metadata registry MDR content consistency — Part 1: Data integration is often also solved as a problem of data, rather than metadata, with the use of so-called master data. The primary extension in Edition 3 is the Concept Region, expanding the use of concepts to more components within the standard, and supporting registration of a Concept system for use within the registry.
Organizations exchange data between computer systems precisely using enterprise application integration technologies. The standard also supports the use of externally defined concept systems. The published standards make no reference to editions, so withdrawing Part 2 could cause existing customers confusion or problems with compliance. The second principle from semantic theory is the relation between a concept and its representation, e. This part should refer to content already covered in The eXtended Metadata Registry initiative, XMDR led by the US, explored the use of ontologies as the basis for MDR content in order to provide richer semantic framework than could be achieved by lexical and syntax 111779-4 conventions alone.
