preservation change [English]
n. ~ PaaST (Preservation Change) · A preservation action that produces a new binary encoding of a preservation target.
- PaaST (1.0) 2017 (†860 p. 48): A Preservation Change may be necessitated by the obsolescence of one or more DigitalComponents in a BinaryEncoding. Preservation Change might also be effected in accordance with a policy that requires standardizing formats for certain classes of objects. A Preservation Change process might also be executed to respond to a request by an external Access Client for a copy of a DigitalComponent in a special format; however, this process might be limited to delivering the requested copy without creating a new Binary Encoding that is maintained in the Preservation Environment. A Preservation Change may involve modifying or replacing any or all DigitalComponents in a BinaryEncoding, including ContentObjects, SoftwareObjects, and InstantiationObjects. (†2540)
