InterPARES Definition

n. ~ PaaST (Preservation Service Contract ) · An agreement between a preservation service provider and a preservation director for the provision of one or more preservation services.


  • PaaST (1.0) 2017 (†860 p. 11): In a scenario where preservation is accomplished in the Cloud, one or more Initial Sources reach Preservation Agreements with a Preservation Director who accepts responsibility for preservation of digital information assets. The Preservation Director then enters into a Preservation Service Contract with a Preservation Service Provider who provides the technological resources necessary for preservation and carries out preservation activities as directed by the Preservation Director and, presumably as specified in the Preservation Service Contract. However, an Initial Source could retain authority over the materials it wants preserved and thus also act as Preservation Director. Also, a Preservation Director could provide some preservation services in house and only contract with a Preservation Service Provider for a limited set of preservation activities. Alternatively, the Preservation Director might rely on Preservation Service Providers for all preservation services, but rely on one provider for basic ongoing services, such as processing of Submissions and storage of Preservation Targets, while awarding other contracts for specialized services, such as format conversion.

  • PaaST (1.0) 2017 (†860 p. 40): Thus, an important part of any Preservation Service Contract is to specify which requirements must be satisfied; moreover, the contrast should also specify where and when particular requirements should be applied. These contract specifications should then be translated into executable Preservation Rules. (†2566)
