Abstract
Abstract Our linking method is implemented in our linking system which includes an interconnection network, which employs a standard directory protocol, such as X.500, and linking components. The interconnection network includes interfaces for interconnection users and local directories. The linking components include linking directories and linking applications which are connected to the interconnection network via interfaces. Linking directories contain entries, and each entry comprises linking references pointing to entities, which include local directories and linking applications and have access to information about the object in different contexts. In the linking directory, there is an entry for each object, and this entry is accessible using a linking identifier unique the object. The linking application coordinates a response to the user's request and sends queries to the linking directory, local directories, and other linking application to fulfill user's requests. A user can access requested information by inputting known information about an object in one context along with a request for information about the object in another context. The known information is used by the linking application to query a local directory in the network for the linking identifier corresponding to the object. The linking application then uses the linking identifier to query the linking directory for linking references pointing entities having further access to information about the object in the specified context. The linking application uses the linking reference to locate the entities pointed to and the linking identifier as a key to retrieve the requested information. This retrieved information is formatted by the linking application and forwarded to the user in response to the request.
