Local Replica Catalog
From GridPP Wiki
The Local Replica Catalog was the catlog component which mapped Globally Unique Identifiers (GUIDs) to Storage URLs in the EDG Replica Manager and the Globus Replica Location Service. When combined with the Replica Metadata Catalog (which mapped LFNs->GUID) this produced a complete Grid File Catalog.
Installing
It's unlikely that anyone would want to install this as a file catalog, given the existance of the LCG File Catalog and FiReMan, however there is an install guide on the GOC wiki:
