Promoting and Enhancing Reuse of Information throughout the Content Lifecycle taking account of Evolving Semantics



A new approach is needed to ensure that the digital objects created today are available and useful for future generations of users. As scientific, engineering, and media assets and their related metadata are generated across different lifecycle phases, in a continually evolving environment, the concept of a fixed and stable “final” version becomes less relevant. Preservation systems have focused too much on the static and technical conservation of digital objects; such systems do not only fail to solve the challenge of maintaining reusability but are in fact themselves part of the challenge; like the digital objects they preserve, they need to evolve in the face of a changing technical and organisational environment. They form part of an evolving preservation ecosystem that includes not only digital objects and technical systems but also policies, the processes by which these policies are implemented and the services that combine to form these processes.

PERICLES will address these challenges by developing extensions to current preservation and lifecycle models that address the evolution of dynamic, heterogeneous resources and their dependencies in changing environments, including policies, processes, semantics, and users, as well as the content itself. Maintaining the complex dependencies between the components of the preservation ecosystem is key to achieving “preservation by design”, through models that capture intents and interpretative contexts, and thus enabling content to remain relevant to changing communities of users. These models will be complemented with a suite of tools that implement functionality in support of these models.

The project outputs will be validated against a corpus of user scenarios relating to the preservation of highly complex and dynamic and/or large-scale digital assets, derived from real-life contexts in (i) digital media and contemporary art, and (ii) space science.
