This page contains a Registry Capability Comparison Matrix (RCCM) and supporting details. Its was developed to help the OASIS egov TC define registry requirements for egov, and to determine how different Registry standards meet the identified requirements.

Please send any mistakes or corrections to

What is Include

The RCCM currently only includes standards for directories, registries and registry/reopositries. This list may be incomplete.

What is Not Included

The RCCM does not currently include products. This is because we cannot be partial to one product or another.

The RCCM does not currently include general catgories (e.g. Ontological Registries ). This is because it is difficult to fill out the matrix for a broad category.
