Using capability profiles for appliance aggregation

We describe how several existing standards try to address specific use cases for appliance aggregation. These standards all rely on devices being able to describe their capabilities to other devices. In order to do this, each standard defines its own idiosyncratic profile structure and profile vocabulary. Furthermore applications using this information often need to perform standard tasks such as selection, generation or adaptation based on this information. The problems of devising profile vocabularies, profile structures and matching and selection algorithms are already being explored in the adaptable Web delivery project in HP Labs. We discuss the relevance of this work to appliance aggregation and highlights steps that can be taken to resolve the current proliferation of standards.

Semantic Middleware for E-Discovery

E-Discovery is the process of collecting, preparing, reviewing and producing electronically stored information in the context of the legal process. In this paper we describe practical experiences developing semantic middleware to support E-Discovery from a variety of enterprise data sources including relational databases, LDAP directories and document repositories. Specifically we discuss the development of a top level ontology suitable for representing enterprise data for E-Discovery, a semantic mapping process that maps the data models of these heterogeneous sources into the top level ontology, a data integration step that merges references to the same entity from different sources, and a query controller that provides a common, coordinated view for applications consuming these sources.
