This paper describes how an ODP Trader can be implemented using the X.500 Directory Standard. It differs from previous work in this area as we concentrate on the details of the X.500 interface for an ODP Trader, rather than the implementation of the Trader agent itself. We take the ODP specification and describe how the functionality can be supported using X.500. Because of the different data and operations models it is not possible to directly replace an ODP Trader with X.500. Instead, X.500 is used to store the Trader information, including the Service Offers, Links to interworking Traders, and information about the Trader itself. The Trader functionality is implemented using a specialised X.500 user agent, the T-DUA. The T-DUA uses the X.500 operations, particularly search, to interrogate and manipulate the Trader database. Use of X.500 in this way simplifies the implementation of the Trader. |
