Preservation Watch is a well-accepted concept now, first created during the European FP7 project PLANETS in a working group consisting of me and Paul Wheatley. As part of the Planets Functional Model it combines and extents the monitoring activities as mentioned in OAIS. As such it is a valuable contribution to a better description of the Preservation Planning Functional Entitiy and worthwhile considering to add this concept of Preservation Watch to the OAIS standard.


The Planets Functional Model identifies 3 key preservation functions: Preservation Watch, Preservation Planning and Preservation Action. A detailed description can be found here, this blog focuses on Preservation Watch. Preservation Watch monitors a variety of internal and external entities, including the content preserved in the digital repository itself (via ADMINISTRATION). Where potential changes in the entities are identified (e.g. a new tool is available, a platform is no longer supported, or a new use case becomes popular), the resulting preservation risk is assessed. Critical or imminent risks are passed to Preservation Planning for further analysis and planning of subsequent action. Information gathered from the entities and analysed in the Testbed is used to provide Representation Information Updates to the KNOWLEDGE BASE . For example, the addition of a KNOWLEDGE BASE entry describing a new tool and its capabilities. Preservation Planning assesses Constraints and Risks received from Preservation Watch. Preservation Action performs actions on Content to ensure its continued accessibility and sends appropriate feedback to Preservation Watch.

The Preservation Watch has 4 subfunctions:
