In general one OAIS is not interoperable with another; however, there are a number of reasons that some level of interoperability may be desirable, motivated for example by Users, Producers or Management; even interoperable Archives may have different Designated Communities—even for the same digital objects—and hence different requirements for Representation Information and/or Descriptive Information.

In general one OAIS is not interoperable with another; however, there are a number of reasons that some level of interoperability may be desirable, motivated for example by Users, Producers or Management; even interoperable Archives may have different Designated Communities—even for the same digital objects—and hence different requirements for Representation Information and/or Descriptive Information.

OAIS associations can be categorized technically by both external and internal factors. External factors include characteristics of the Producer and Consumer communities. Internal factors could include common implementations of the information models presented in 4.2, or multi-Archive sharing of one or more of the functional areas presented in 4.1.

This subsection defines four categories of Archive association. The first three categories have successively higher degrees of interaction:

Independent: Archives motivated by local concerns with no management or technical interaction among them.

Cooperating: Archives with potential common producers, common submission standards, and common dissemination standards, but no common finding aids.

Federated: Archives with both a Local Community (i.e., the original Designated Community served by the Archive) and a Global Community (i.e., an extended Designated Community) which has interests in the holdings of several OAIS Archives and has influenced those Archives to provide access to their holdings via one or more common finding aids. The Access needs of the Local Community usually have priority over those of the Global Community. Global dissemination and Ingest are optional features.

Shared resources: Archives that have entered into agreements with other Archives to share resources, perhaps to reduce cost. This requires various standards internal to the Archive (such as ingest-storage and access-storage interface standards) but does not alter the user community’s view of the Archive.

The remainder of this subsection gives a more detailed view of these categories of association.


6.1.1 INDEPENDENT ARCHIVES

6.1.2 COOPERATING ARCHIVES

6.1.3 FEDERATED ARCHIVES

6.1.4 ARCHIVES WITH SHARED FUNCTIONAL AREAS
