Implementation Issues in an Open Architectural Framework for Digital ObjectServices
Lagoze, Carl; Ely, David
We provide high level designs for implementing some key aspects of the Kahn/Wilensky Framework for Distributed Digital Object Services. We focus on five aspects of the architecture: 1) Negotiation on terms and conditions initiated by requests for stored digital objects. 2) Replication of handle server data and the notion of a primary handle server, 3) The mechanisms for replicating digital objects in multiple repositories and the assertions concerning such replication. 4) The meaning of mutable and immutable states for digital objects and the mechanisms for changing these states. 5) The basic services that the Repository Access Protocol (RAP) needs to support the infrastructure.
