Registries and Resources

Top

Since every resource registered in a SPASE compliant system has a unique resource identifier, finding a resource is made possible with a registry service. A registry service will translate a resource identifier into the resource description (metadata) for the resource. SPASE provides a set of registry services which a naming authority can use to register and share resource descirptions.

The SPASE group maintains a registry for conceptual (i.e., services) and physical (i.e., people) resources. It's located at http://spase-group.org/registry.

Digital resources (i.e., data) are registered at other locations like a virtual observatory.

When describing data resources references to other resources are made using the resource's identifier. A quick check at the SMWG Registry can save you from writing many of the required resource descriptions.
