Examples of org.locationtech.udig.catalog.IServiceInfo

org.locationtech.udig.catalog.IServiceInfo
Provides metadata information about a service.
Information is provided in the form of a single, simple, Java bean. You can treat this bean as a "view" on more complete metadata information that may be accessable via a subclass (or other resolve target). This bean offers up service metadata information to the uDig search facilities, this information may also be displayed to users.

Much of the names and motivation have been taken from Dublin Code and it's application profile for RDF.
