From the National Institute of Standards Organizations:
The National Information Standards Organization (NISO) and the Open Archives Initiative have been awarded a $222,000 grant for a joint project to develop a new open standard on the real-time synchronization of Web resources. Increasingly, large-scale digital collections are available from multiple hosting locations, are cached at multiple servers, and leveraged by several services. This proliferation of replicated copies of works or data on the Internet has created an increasingly challenging problem of keeping the repositories’ holdings and the services that leverage them up-to-date and accurate. As we move from a Web of documents to a Web of data, synchronization becomes even more important: decisions made based on unsynchronized or incoherent scientific or economic data can have serious deleterious impact.
“This proposal is an outgrowth of the issues exposed in the context of the Memento project that developed a protocol for uniformly accessing time-stamped resource versions on the Web,” explains Michael L. Nelson, Associate Professor, Old Dominion University Computer, and a principal investigator on the Memento project. “We have assembled a stellar core team to devise the standard from the Sloan grant. It includes people that have worked on a variety of information interoperability efforts such as Memento; the OAI Object Reuse and Exchange (ORE), a protocol for describing aggregations of Web resources; Open Annotation, a resource-centric annotation framework; and the DSNotify change detection framework for Linked Data.”
“The OAI Protocol for Metadata Harvesting (PMH) 2.0 specification can be used to effectively synchronize the metadata about the resources,” states Carl Lagoze, Associate Professor, Cornell Information Science, and OAI Executive, “but synchronizing the resources themselves was never specified. Although some resource synchronization methods exist, they are generally ad hoc, arranged by the individuals involved, and cannot be universally deployed.”
“As we started to explore this problem domain, it became increasingly clear that an interoperable, efficient and lightweight mechanism to support synchronizing resources at scale is missing from the Web infrastructure;” states Herbert Van de Sompel, Scientist, Los Alamos National Laboratory, OAI Executive and a principal investigator on the Memento project. “Candidate technologies that can help to tackle the problem exist, but they need to be put together and profiled in an appropriate manner.”
