Gap Identification Services

As underlined in the OAIS model, there is a need for services that help archivists in checking whether the archived digital artefacts remain understandable, and to identify hazards and the consequences of probable losses or obsolescence risks. In SCIDIP-ES, we have defined the Gap Identification Service (GIS) to facilitate such assessments of intelligibility of digital objects by identifying “gaps” in the corresponding RepInfo Network in the RepInfo Registry (Figure 3Figure 3). In essence, this service is inspired by a model that consists of the notions of module, dependency and profile. If applied to digital objects, a module can be a software/hardware component or even a knowledge base expressed either formally or informally, explicitly or tacitly, that we want to preserve, while the dependency being the logical links and the meaning between modules. In addition, a module may require the availability of other modules in order to function, be understood or managed (e.g. a network of RepInfo). A profile is the set of modules that are assumed to be known (available or intelligible) by a user (or community of users), so this is an explicit representation of the concept of Designated Community Knowledge Base (KB). Utilising this model, the GIS is able to check whether a digital object (module) is intelligible by a community, or to compute the intelligibility gap (e.g. new version of the object, new user, changes in user knowledge) of a digital object.

In an archive, the GIS can be used in the preservation planning process to evaluate the current knowledge base of the designated community as well as future review(s) of the plans by analysing changes in the knowledge base.
