【 摘 要 】

The goal of the Replica Registration Service (RRS) is toprovide a uniform interface to various file catalogs, replica catalogs,and metadata catalogs. It can be thought of as an abstraction of theconcepts used in such systems to register files and their replicas. Someexperiments may prefer to support their own file catalogs (which may havetheir own specialized structures, semantics, and implementations) ratherthan use a standard replica catalog. Providing an RRS that can interactwith such a catalog (for example by invoking a script) can permit thatcatalog to be invoked as a service in the same way that other replicacatalogs do. If at a later time the experiment wishes to change toanother file catalog or an RLS, it is only a matter of developing an RRSfor that new catalog and replacing the existing catalog. In addition,some systems use metadata catalogs or other catalogs to manage the filename spaces. Our goal is to provide a single interface that supports theregistration of files into such name spaces as well as retrieving thisinformation.
