preservation target [English]
n. ~ PaaST (PreservationTarget) · An intellectual entity that is designated for preservation.
A Preservation Target is either a Preservation Object, Preservation Object Set, or a Preservation Data Object. See UML diagram.
- PaaST (0.11) 2016 (†778 ): The class, Preservation Target, has two child classes: Preservation Object and Preservation Aggregate. (†1979)
- PaaST (1.0) 2017 (†860 p. 14): An IntellectualEntity has two subclasses, PreservationTarget and HeuristicInformation. A PreservationTarget is something that is preserved. HeuristicInformation is human readable information that is important in helping people to understand and interpret correctly the information conveyed by a PreservationTarget. These two subclasses are not mutually exclusive. An information object could be both a PreservationTarget and HeuristicInformation. The distinction depends essentially not on what the object is, but on the context in which it is managed, processed or used. (†2444)
- PaaST (1.0) 2017 (†860 p. 14): Ideally, a PreservationTarget should not change; however, the uncertainty of the evolution of information technology means that there is no guarantee that future Instantiations will preserve all properties without change. (†2570)
- PaaST (1.0) 2017 (†860 p. 25): Like all IntellectualEntities, a PreservationTarget exists in its proper form only temporarily as instantiated in a RuntimeVersion or Manifestation. For a PreservationTarget, then, remaining in a definitive state translates into every Instantiation being identical in all essential respects. The essential properties are articulated as PermanentFeatures of the PreservationTarget. (†2571)
