Description
A key advantage of Grid systems is the capability of sharing
heterogeneous resources and services across traditional
administrative and organizational domains. This capability enables
the creation of virtual pools of resources that can be assigned to
groups of users. One of the problems that the utilization of such
pools presents is the awareness of the resources, i.e., the fact
that users or user agents need to have knowledge of the existence
and state of the resources. This awareness requires the presence of
a description of the services and resources typically defined via a
community-agreed information model. One of the most popular
information models is the GLUE Schema that is providing a common
language to describe Grid resources for a number of Grid
infrastructures. Other approaches exist undertaking different
modeling strategies. The presence of different flavors of
information models for Grid resources is a problem for enabling
inter-Grid interoperability. In order to solve this problem, the
GLUE Working Group in the context of the Open Grid Forum was
started. The purpose of the group is a major redesign of the GLUE
Schema that should consider: the successful modeling choices and
flaws which have emerged from practical experience; use cases and
modeling choices of other information modeling initiatives. In this
paper, we present the status of the new model for describing
computing resources as the first outcome of the working group. The
purpose is to disseminate the result and solicit feedback from the
community.
