This naming authority ivo-id will appear on all data service provided in the VO. This construction will also simplify the search of resource coming from a specific institution or project, so take some time to construct it.

Data Services

The construction of an ivo-id rely upon the naming authority it depends on. We suggest here a construction rule that is aiming at facilitating the addition of new data services, as well as facilitating there discovery.  We propose to follow a hierarchical (path-like) structure, starting from the naming authority, and cascading down to the service itself. For instance, if you want to declare an EPN-TAP service sharing data from a database called "my_database" in a "my_group" team from a "my_lab" laboratory, you would have: ivo://my_authority/my_lab/my_group/my_database/epn.
