WS-DAI RDF(S) Realization: Introduction, Motivational Use Cases and Terminologies
Mario Antonioletti, Miguel Esteban-Gutiérrez, Isao Kojima · 2009
The Database Access and Integration Services Working Group (DAIS-WG) has submitted three specifications to the Open Grid Forum (OGF) recommendation track [WS-DAI, WS-DAIR, WSDAIX]. These specifications define a basic set of interfaces, properties and patterns for servicebased access to data. The core WS-DAI specification outlines a set of generic interfaces and properties that are common to most types of data access. These may then be extended to access specific types of data. For instance, the WS-DAIR and WS-DAIX specifications extend the base specification to provide access to relational and XML types of data respectively. This document outlines and motivates a further extension to the WS-DAI family of specifications to provide access to RDF(S) data. This will define a standard mechanism for accessing RDF(S) data in a manner consistent with the framework defined by the WS-DAI core specification. The main outcome of this work will be two specifications that provide complementary ways for accessing RDF(S) data: by using the W3C defined SPARQL [SPARQL] query language or through the use of ontological primitives. This document motivates this work by presenting an overview of the role of RDF(S) in a grid context with several motivational use cases.
