A system, method and apparatus for locating and accessing information resources in a distributed information network is disclosed. When an end user desires to retrieve an ID for a particular profile associated with a resource, a client program (resident on a client computer) sends an ID request in the form of an HTTP request to an ID authority server computer. In response to the ID request, the ID authority server computer returns a URL of an ID registry server computer corresponding to the requested profile type. The client program then sends a query based upon the returned domain name to the ID registry server. The ID registry server, in turn, returns a URL of an ID host server computer associated with the requested ID so, in one implementation, the client can invoke a program that is superset of the domain name. Once the client program has the location of the ID host server computer, the client program sends a request to the identified ID host server computer. The identified ID host server computer, in turn, responds by returning a list of all facets in a profile, or in some cases, one facet at a time. |
