Description and objectives

Focus and Purpose

The CGS working group wants to define a new Grid information model based on the Common Information Model (CIM) that is being standadized by the DMTF (www.dmtf.org) and thus replace the work produced by the Grid Object Specification activity. A common information model is needed as base of interoperability between the object definitions of the different Grid Working Groups and in this community CIM finds more and more interest as a possible solution for satisfying this need.

The results of this working group will help in the creation of an interoperable Grid architecture, and will thus have impact on deployment and operations. Since it is work on a meta information model no special security issues will have to be addressed.

Goals

The group expects that the following goals will be pursued and met:
  • Main goal is to produce CIM specifications of not yet standardized classes urgently needed in the GGF. To be able to deliver results in the frame of a normal GGF WG lifetime of 18 Month the WG will focus on one topic namely Job Submission Interface. The respective requirements of the OGSA WGs will be taken into account.
  • Specify how the new CIM classes for representing Job Submission Interfaces should be mapped into XML and LDAP. Future GGF work on CIM will show if these mappings can be reused for other CIM classes. The inherent generalization capabilities will be taken into account.
  • Liaise with the DMTF and promote CIM definitions made in the GGF to the DMTF for adoption in their standards.
    • In addition, the group may pursue the following goals:
  • Analyse the current CIM standard and determine which parts can be used to map the resources required, a subset of which has been specified in the frame of the GLUE-Schema work. This could lead to a CIM profile for Grid computing. Such a profile especially defines the schema that should be supported by OGSA. This work also determines which resources required in grid computing are not yet standardized in CIM and thus points to future CIM related work to be accomplished by follow up GGF WGs.
  • Exploring the possible use of evolving CIM based Open Source software in Grid computing.
  • Presenting the results of the WG to the other Grid Working Groups.
