The GLUE Schema

The data published in the Information Service conforms to the GLUE (Grid Laboratory for a Uniform Environment) Schema, which defines a common data model to be used for resources monitoring and discovery.

• General Attributes: This group includes general attributes that are defined in entries of both CEs and SEs, the schema version, the URL of the IS server and finally the GlueKey.

• Attributes for the Computing Element: Information about a CE and its WNs.

• Attributes for the Storage Element: Information about a SE and the corresponding storage space.

• Attributes for the CE-SE Binding: The CE-SE binding schema represents a mean for advertising relationships between a CE and a SE (or several SEs).

The command lcg-info --list-attrs --vo ific shows all the available attributes:
