We present the implementation and performance of a ReplicaSet service based on the specification developed in the OGSA Data Replication Services (OREP) Working Group of the Global Grid Forum. This standard is based on the Open Grid Services Infrastructure. The ReplicaSet service aggregates information about replicated data items and enforces policies for authorization, replica semantics and consistency.
