XML Based Semantic Data Grid Service

چکیده
This paper introduces a novel wrapper-mediator based semantic data grid service mechanism to solve the problem of Semantic heterogeneity and few compatible data sources. It uses ontology based semantic information to wrap the heterogeneous data source, and employs mediator structure to supply accessing interface for the data sources, and it extends semantic query, mapping and fusion languages to support semantic grid communication mechanism. The extension of XML algebra with semantic query enhanced is discussed to enable semantic querying on data gird environment.

A standard transformation from XML to RDF via XSLT
A generic transformation of XML data into the Resource Description Framework (RDF) and its implementation by XSLT transformations is presented. It was developed by the grid integration project for robotic telescopes of AstroGrid-D to provide network communication through the Remote Telescope Markup Language (RTML) to its RDF based information service. The transformation’s generality is explaine...
متن کاملAutomating Metadata Web Service Deployment for Problem Solving Environments
XML-based metadata information services are a crucial core service needed by Problem Solving Environments built over emerging service-based, globally-scaled distributed systems, as envisioned by the Open Grid Services Architecture and the Semantic Web. Developing user interfaces and services bindings for manipulating instances of particular schemas is thus extremely important and needs to be ma...
متن کاملXML Declarative Description with First-Order Logical Constraints
The expressive power of XML Declarative Description (XDD), a unified XML-based representation language for the Knowledge Grid, is enhanced by a well-defined mechanism for modeling arbitrary XML first-order logical constraints (FLCs)—a special kind of constraints comprising XML expressions and logical symbols. The resulting knowledge representation can uniformly express explicit and implicit inf...
متن کاملDynamic computational workflows: Discovery, optimisation and scheduling
The Grid computing community is converging on a service-oriented architecture in which applications are composed from geographically-distributed, interacting web services, and are expressed in a workflow description language, usually based on XML. Such workflows are viewed as offering a useful representation of service-based applications or applications composed of standalone components that ar...
متن کاملHeuristic Approach to Manage Semantic Heterogeneity and Data Inconsistency in Enterprise Data Integration
XML syntax and semantic validations are critical to the correct service transaction specification and service integration based on existing distributed and heterogeneous computing services. Current industry practice of XSLT-based Schematron validation may produce invalid results, and contributes a reusable XML validator component that supports sound integrated syntax/semantic validations and ev...
