Bridging Communities: Semantically Augmented Metadata for Services, Grids, and Software Engineering

摘要

In large-scale distributed systems, seman-tically rich metadata that describe entities in a machine-process-able way are of key importance. Examples of such metadata are the behavioral description of interfaces in service-oriented architectures and the description of resources in Grid environments. Semantics-rich descriptions are necessary prerequisites for automatic management, automatic configuration, and user-friendly discovery of entities. They are crucial to resolve interoperability problems in large heterogeneous environments. Researchers from different fields have been working on this topic. The Semantic Web community outcomes various ontologies for service description. The Grid community has started the Semantic Grid initiative, which exploits technologies from the Semantic Web community such as ontologies and Description Logics. The Software Engineering community has contributed a variety of graph-based approaches to describe the behavior of services to support the software engineering process and for dynamic composition of modules and services.
