In order for users to identify appropriate resources within a Grid infrastructure there must be some form of resource 
information, provided through standard schema and with standard query mechanisms. Many (if not most) production grid 
projects today in the science and engineering community use some form of the GLUE schema for historical reasons, however
 CIM is widely adopted within industry as a standard system resource schema, and the organization developing CIM (DMTF) 
is starting to work closely with the Grid community through its alliance with GGF. NAREGI has experience extending the 
CIM schema to be applicable to Grids, as well as building an actual distributed information system for grids that can 
collect information from the information providers, perform translation and store the information into the CIM database,
 and allow the clients to query the info using the extended CIM schema and the OGSA-DAI service API. A separate activity
, primarily in the UK with the UniGridS project, has been looking at the commonalities as well as the differences 
between Glue and CIM, including possible mappings between them.  .
