The IWorkspaceDomains interface is used for managing the collection of domains found within a workspace. Domains may be shared between fields in different object classes, thus they are managed (that is, created, deleted and modified) at the workspace level. It is important to keep in mind that a domain may not be deleted from a workspace if any field in an object class currently uses it. Domain names are also unique across a workspace; if you attempt to add a domain to a workspace and the specified name is already associated with an existing domain, an error will be returned.

Three of the four properties on the IWorkspaceDomain interface are used for returning to the user the domains that are currently associated with the workspace. The user can either request all of the domains (Domains), a particular domain by name (DomainByName), or all the domains that may be associated with a given field type (DomainsByFieldType).
