Web Services Data Access and Integration – The Core (WS-DAI) Specification

Data resources play a significant role in many applications across multiple domains. Web services provide implementation neutral facilities for describing, invoking and orchestrating collections of networked resources. The OGF (Open Grid Forum) Open Grid Services Architecture (OGSA), and its associated specifications, defines consistent interfaces through web services to components of a grid infrastructure. Both the web and grid communities stand to benefit from the provision of consistent and agreed web service interfaces for data resources and the systems that manage them. This document presents a specification for a collection of generic data interfaces developed by the Database Access and Integration Services (DAIS) Working Group that can be extended to support specific kinds of data resources, such as relational databases, XML repositories, RDF data sources, or files. Related specifications define how specific data resources and systems can be described and manipulated through such extensions. The specifications can be applied in regular web service environments or as part of a grid fabric. GFD-R.74 17 April 2012 dais-wg@ogf.org 2
