IEC Common Data Dictionary

- This means the IEC CDD is a database providing classifications and metadata definitions for describing products.

IEC CDD originally was intended to support electronic exchange of digital information (e.g. for e-commerce [1]).

New information concepts related to smart manufacturing and Industrie 4.0 are based on use of IEC CDD and similar dictionaries.

Such annotated data values then can be exchanged within one production system between machines of different manufacturers or between different companies.

Such a definition for a property representation can be used as base for product descriptions in e-catalogues or for B2B communications (see B2B e-commerce).

Each of these domains can be accessed directly using the HTML user interface of IEC CDD, and there is hierarchical browsing.
