Abstract:
A current problem that exists for mobile devices is
the discovery, display and use of local or global
services as they are found on-the-fly by a roaming
mobile device. Currently service registries are
centralized and typically use global ontologies. In
addition given the multiple mobile device types,
creating and maintaining multiple user interfaces for
differing device types can be costly for providers. This
paper proposes a common and novel solution to these
problems that makes use of XML Schema to autogenerate
client-side display interfaces to both services
and to ontologies of services. This approach has the
advantages that it does not assume or require a global
ontology or registry of services, it provides a general
architecture enabling automatic creation of service
interfaces for roaming mobile devices and it provides a
mechanism for local service discovery.
