Charter for DAIS-WG
Date 2013-05-23
Group Abbreviation:
dais-wg
Group Name:
Database Access and Integration Services WG
Area:
Data
Group Leadership:
| Isao Kojima | kojima@ni.aist.go.jp | Chair |
| Mario Antonioletti | mario@epcc.ed.ac.uk | Chair |
Group Summary:
Research and development activities relating to the grid have generally focused on applications where data is stored in files. However, in many scientific and commercial domains, database management systems have a central role in data storage, access, organisation, authorisation, etc, for numerous applications. The group is developing standards for grid data services, focusing principally on providing consistent access to existing, autonomously managed databases from web services. By focusing on services, the intention is to ease application development through the provision of composable components. The group does not seek to develop new data storage systems, but rather to make such systems more readily usable individually or collectively within a grid framework.
Charter Focus/Purpose and Scope:
The group has been working on the development of a family of data access and integration specifications. The WS-DAI specification defines data model independent properties and operations that are shared by interfaces to different kinds of data resource. These properties are then extended and the templates instantiated by realisations - data model specific data access services. At first, the group has focused on realisations for accessing relational (WS-DAIR) and XML (WS-DAIX) data resources. The specifications for WS-DAI, WS-DAIR and WS-DAIX are have all been submitted to the GGF Recommendations track. The group is extending the activity to set the RDF access specification WS-DAIRDFS.
Goals/Deliverables:
Title: Grid Database Access and Integration: Requirements and Functionalities

Title: Web Services Data Access and Integration (WS-DAI).
Abstract: This document, Web Services Data Access and Integration (WS-DAI), presents a specification for a collection of generic data interfaces that can be extended to support specific kinds of data resources, such as relational databases, XML repositories, object databases, or files.

Seven Questions:
1. Is the scope of the proposed group sufficiently focused?
2. Are the topics that the group plans to address clear and relevant for the Grid research, development, industrial, implementation, and/or application user community?
3. Will the formation of the group foster (consensus-based) work that would not be done otherwise?
4. Do the group's activities overlap inappropriately with those of another OGF group or to a group active in another organization such as IETF or W3C?
5. Are there sufficient interest and expertise in the group's topic, with at least several people willing to expend the effort that is likely to produce significant results over time?
6. Does a base of interested consumers (e.g., application developers, Grid system implementers, industry partners, end-users) appear to exist for the planned work?
7. Does the OGF have a reasonable role to play in the determination of the technology?
Group Status:
