Preservation Preparation. 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 aims to determine the value of a resource. This value may change over time and Figure 6: Preservation Preparation Workflow in the Remember & Forget Layer 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 content ap- praisal have always been part of the processes of an archive [Xxxxxx, 2006], al- though not always as much in personal archiving [Xxxxxxxx, 2011]. The component for appraisal and managed forgetting aims to help in automating such decisions, a need that has been identified earlier [Xxxxxx and Xxxxxxxx, 0000], for both per- xxxxx archiving as well as organizational settings. This is encapsulated in the con- cept of managed forgetting, which uses the results of content value assessment for deciding about preservation and forgetting actions. The effects of managed forget- ting functionality is not restricted to the preservation functionality. It can also be used in the Active System for improved information access. Furthermore, the workflow steps pr...
