Remember & Forget Layer. The Remember & Forget Layer introduces brain-inspired functionality into the PoF Ref- erence Model, which targets the concepts of managed forgetting and contextualized re- membering. For this purpose, the Remember & Forget Layer extends the two workflows Preservation Preparation and Re-activation from the Core Layer with further, more ad- vanced functionalities: Content Value Assessment, Managed Forgetting & Appraisal, De-contextualization, Contextualization, Re-contextualization and Search & Navi- gation, which are all described in the following. All of those listed functionalities create additional metadata, which have to be managed in a systematic way. Therefore, the Re- member & Forget Layer also contains a functional entity for Metadata Management. In more detail, the Preservation Preparation workflow, which still consists of the five steps select, provide, enrich, package and transfer (see Figure 6), now uses the additional functionalities of Content Value Assessment and Managed Forgetting in the phase of selecting content for preservation: Content Value Assessment Understanding the value of content is in the core of con- tent appraisal for preservation and managed forgetting. Content value assessment Figure 6: Preservation Preparation Workflow in the Remember & Forget Layer aims to determine the value of a resource. This value may change over time and there are different value dimensions, which reflect the value considering different purposes or perspectives and which may influence each other. There is, for exam- ple a value dimension reflecting current importance, e.g. Memory Buoyancy (MB), and a dimension reflecting the long term importance or relevance of a resource, the Preservation Value (PV). For assessing content value, the content value assess- ment component takes evidences from the Active System, e.g. about information use, content creation, and further knowledge about the role of resources in the Active System. Content value can be used as a basis for making preservation deci- sions, e.g. if a resource should be preserved or how much should be invested in the preservation of a resource. Content value can also be used in the Active System, e.g. for especially highlighting resources with high content value. Managed Forgetting & Appraisal With the dramatic growth of the amount of content, nowadays it becomes more and more important to make conscious decisions about preservation. Clear decisions on what to put into the DPS and explicit cont...

All of those listed functionalities create additional metadata, which have to be managed in a systematic way. Therefore, the Re- member & Forget Layer also contains a functional entity for Metadata Management. The workflows mentioned above define activities that contain rules, constraints, and settings, that should be agreed upon and that could be defined in a Preservation Contract. This contract is handled by the functional entity Preservation Contract Management which potentially relate to many, if not all, entities and are not drawn in the figures to avoid clutter.
