The Moab Design for Digital Object Versioning
- The Stanford Digital Repository has adopted the “Moab” design for versioned archiving of digital objects–a locally developed approach that optimizes data transfer, storage, and replication while providing efficient single file retrieval or full object reconstruction for any version of an object. This paper includes a review of various versioning strategies including forward-delta, reverse-delta and content-addressable mechanisms, the pro’s and cons of each, and highlights the relative advantages of the Moab design. In our approach, the fixity information of a file manifestation is used as its primary identifier and the filename is treated as metadata. Storage and retrieval of an object’s files is facilitated by mapping between a virtual version inventory and the physical location via a file signature catalog.
