GRID Information Service

The grid Information Service (IS) provides information about the grid resources and their status. This information is essential for the operation of the whole grid, as it is via the IS that resources are discovered. The published information is also used for monitoring and accounting purposes.
Much of the data published to the IS conforms to the GLUE Schema, which defines a common conceptual data model to be used for grid resource monitoring and discovery.
The IS used at CERN is the Berkeley Database Information Index (BDII).
