InterPARES Definition

n. ~ PaaST (PreservationNetwork) · A set of objects related to the preservation of a preservation target, including its binary encodings, heuristic information that supports its comprehension and use, other preservation management information about it, and any other preservation target associated with the preservation target that is the focus of the network.


  • PaaST (1.0) 2017 (†860 p. 39): Any PreservationTarget has at least one BinaryEncoding and at least two DigitalComponents needed to instantiate it. There may be many more, including additional Binary Encodings and Data Objects, and possibly several HeuristicInformation objects that clarify it. Every DigitalComponent has an associated ComponentDescription. Over time, there will be a growing quantity of PreservationManagementInformation about all of these objects. All of these objects are significant, and many are necessary, for successful preservation of the PreservationTarget. The set of all such objects constitute a PreservationNetwork with the PreservationTarget as its focus. [Note:] The concept of ‘PreservationNetwork’ expands on the OAIS concept of ‘Representation Network,’ but a Representation Network is, by definition, more limited: “The set of Representation Information that fully describes the meaning of a DigitalComponent.” OAIS p. 1-15.
