TS EN 82045-2

TS EN 82045-2 is Part 2 of the document management standard that addresses metadata elements and the information reference model used to organise them. It treats a document not only as a file, but as an information object that can be identified, related and exchanged consistently across its lifecycle, which is essential for controlled document management in technical environments.

How the metadata framework is organised

According to the scope, this part provides a comprehensive set of standardised metadata elements for document management and places them in a standardised information reference model. In general technical terms, metadata is information about a document rather than the content itself: identification, versioning, status, relationships, responsibility and exchange context are typical examples. A shared metadata structure helps different systems interpret the same document data in the same way.

Exchange and implementation context

The standard also provides an EXPRESS-based information reference model and a standardised DTD based on XML for document exchange. EXPRESS is a formal modelling language used to define structured information models, while an XML DTD defines the allowed structure of exchanged document data. Together, these elements support interoperability, consistent data exchange and a practical basis for implementing document management systems.
