Metadata related to the Registry (Label, Control Body, ...)
List of registers: in some cases, not all the Registers available in a Registry need to be federated
Update frequency
To join the federation, each Registry has to provide this information with a kind of Capabilities file (format to be agreed) containing:
Label
URI
Registry Manager /Contact Point
List of URLs pointing to the Register description files (with the agreed exchange format)

<dct:description xml:lang="en">The INSPIRE infrastructure involves a number of items, which require clear descriptions and the possibility to be referenced through unique identifiers. Examples for such items include INSPIRE themes, code lists, application schemas or discovery services. Registers provide a means to assign identifiers to items and their labels, definitions and descriptions (in different languages). The INSPIRE registry provides a central access point to a number of centrally managed INSPIRE registers. The content of these registers are based on the INSPIRE Directive, Implementing Rules and Technical Guidelines.</dct:description>

4. Register your Registry in the Federation
The RoR will harvest the information based on the update frequency specified by requesting the RDF exchange format from the URI specified for each register in the registry metadata file.
It will import and update the information related to the Registry, Registers and Relations.
If the modification date is available, the RoR will compare the last harvesting date with the Register modification date to check the need of update.
Otherwise, there will be a complete harvest of the content specified in the registry file.
