developerWorks: Index Grid Services Using Globus Toolkit 3.0

“Information management is a key issue in the construction of
grid applications. This usually involves the generation,
aggregation and synchronization of information about grid resources
for use in resource discovery, selection, and optimization. In the
Open Grid Service Architecture (OGSA), everything is represented as
a grid service and expresses its state in a standardized way as
Service Data Elements (SDEs).

“As the reference implementation of Open Grid Service
Infrastructure (OGSI), which forms the foundation of OGSA, Globus
Toolkit Version 3.0 (GT3) provides three additional components
referred as GT3 Base Services. Information service, implemented as
the Index Service, is one of the GT3 Base Services. It provides the
functionality within which Service Data can be collected,
aggregated, and queried; data feeds can be monitored; and Service
Data can be created dynamically on demand. This article focuses on
how the Index Service can be used to index grid services, for
example, to index Service Data from multiple grid service instances
through the subscription and notification interfaces that OGSI has
defined…”
