Data Category Registry

Defining widely accepted linguistic concepts

ISO TC 37 Terminology and Other Language and Content Resources

ISO 12620 provides a framework for defining data categories compliant with the ISO/IEC 11179 family of standards. According to this model, each data category is assigned a unique administrative identifier, together with information on the status or decision-making process associated with the data category. In addition, data category specifications in the DCR contain linguistic descriptions, such as data category definitions, statements of associated value domains, and examples. Data category specifications can be associated with a variety of data element names and with language-specific versions of definitions, names, value domains and other attributes.



The Registration Authority of the TC 37 DCR is the Max Planck Institute for Psycholinguistics, Nijmegen, The Netherlands.


This new DCR implementation is currently under development by the MPI in collaboration with TC 37. However, the core services should now be stable enough for day to day DCR usage. We welcome any feedback (bug reports, feature requests, etc.). You can use the following methods to contact us:
