|
A trading object or trader provides the ability to discover
instances of services offered within a distributed system.
This paper proposes a Service Discovery Service
(SDS) for a CORBA environment that can assist client
providers in the construction of their client programs. By
sing the SDS, the client providers will obtain knowledge
of services with required functionality before writing the
client programs to trade for those services with the trader.
The SDS gathers XML service descriptions from multiple
CORBA traders and can discover information on service
types, service interface definitions, and service offers. It
can be thought of as a search engine for service
descriptions and query is possible via keywords and XML
query languages. It is also accessible by both CORBA and
WWW clients with a possibility to enlarge search space by
federation of multiple SDSes.
