GLUE

GLUE is a language to describe Grid components in a platform- and technology- neutral fashion. It main purpose is to allow service discovery; for example, a job landing at a site should be able to query the GLUE information to discover all grid services.

Components within a grid publish a description of themselves using a standard information model. For dCache, the Info Provider provides this description.

Organisation

The GLUE info model is maintained by the  GLUE Working Group, part of the  Open-Grid Foundation (OGF).

History and Future directions

Currently, GLUE v1.3 is commonly used; some components still publish GLUE v1.2 information, which is compatible with clients expecting GLUE v1.3 information.

GLUE v2.0 is the next version of GLUE. It will not be backward compatible with GLUE v1.3, so a new dCache Info Provider will be needed.
