public interface Discovery

A collection of catalog entries that is organized to assist in the discovery, access, and retrieval of geospatial resources or services that are of interest to the user, especially when the existence or whereabouts of the resource are not know to the user.

Being a collection of catalog entries, a catalog should be able to enumerate each of its entries, and should allow entries to be added or removed. It should also support queries that will enable the user to obtain entries of interest based on specified criteria.
