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). The WG will evaluate whether CIM can be used as a common Grid Information model which would replace the work on Grid Object Specification activity. A common information model is needed as base of interoperability between the object definitions of the different Grid Working Groups.

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. Currently the following entities are seen to be needed to be specified:
  • extensions to the service class for specifying Web Services
  • extensions to or redefinition of the Cluster model
  • queueing system information
  • time stamping for soft-state timeout
  • Define a complete set of resources and their relations that are needed in Grid computing. This would formulate the requirements that Grid computing has in terms of a common information model.
  • Analyse the current CIM standard and determine which parts can be used to map the resources required. This work is sort of 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.
  • Specify a GGF CIM Style guide that introduces the Grid community into CIM and shows how new CIM classes should be specified and how mappings of these specifications should be made into XML and LDAP.
  • 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:
  • 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.
