The ECCMA Data Requirements Registry (eDRR) is a repository of cataloging templates, also known as identification guides. There are more than 20,000 templates available to ECCMA Full Members, covering requirements for both products (materials, items) and services.

The eDRR is a shared resource built by ECCMA members that assists their data cleansing and data management projects. Members can research existing data requirements to use as a base or template for creating a new requirement, or register own data requirements in the repository to increase the knowledge base. Templates are composed of terminology from the ECCMA Open Technical Dictionary (eOTD).

Data Requirements are used to define the required characteristic needed to describe a class of items. Typically, data requirements are known as cataloging templates or identification guides, but in reality a data entry form can be expressed in eOTD-i-xml (ISO 22745-30) and registered in the ECCMA Data Requirements Registry.
