bjectClasses

Database Interfaces Delegation Human interface A web query system in the lines of the Schema Registry Project, though with a distributed flavor. Any namespace owner local registry interface should be able to follow the LDAP URIs in the delegation objects, for presenting public URN values, from any participating registry, perhaps in the local language.

Applications. local or foreign, should be able

to query the directory and get information with the appropriate level of access. For example, for obtaining local language human representations of a given URN value.
