ABSTRACT:
In a computer, a system and a method handle requests from a client for accessing metadata attributes from at least one file system having an associated format containing specific metadata attributes. A format agent manages the file system. A client's request is received at an interface and forwarded to a dispatcher. The dispatcher routes the request to the format agent. The format agent fulfills the portions of the client's request regarding metadata attributes included in the associated format of the file system. If the client's request contains a metadata attribute that is not part of the file system's associated format, the format agent accesses a metadata attribute store to retrieve the metadata attribute data needed to fulfill the request. The requested metadata attribute data is then returned to the client. Multiple instances of the metadata attribute data are accessible by the client, the instances selected and/or assigned by the client and/or the system.
