Title
DartGrid: RDF-mediated database integration and process coordination using grid as the platform
Abstract
In presence of web, one critical challenge is how to globally publish, seamlessly integrate and transparently locate geographically distributed information resources such as databases, programs, process, etc. DartGrid is an implemented prototype system whose goal is to provide a semantic solution capable of deployment in grid settings. With current implementation of DartGrid, two fundamental resources , data and process, are considered and integrated together to provider semantic-level services. Our approach mainly involve the following notions: a) resource providers are organized as an ontology-based virtual organization; by uniformly defined domain semantics, data and process resources can be both semantically registered to an ontology-based index and seamlessly integrated together to provide high-level service, and, b)we raise the level of interaction with the system to a domain-cognizant model in which data query request and process execution command are specified in the terminology and knowledge of the domain(s), which enable the users to query databases and execute processes at a semantic or knowledge level. We explore the essential and fundamental roles played by semantics, and develop a Semantic Browser with some innovative semantic functionalities such as graphically browsing RDF/OWL ontologies, visually constructing semantic queries and semantically registering the data and process resources.
