Semantic Digital Archives Preface

Current digital preservation is strongly biased towards data objects: digital files of document-style objects, or encapsulated and largely self-contained objects. To provide authenticity and provenance information, comprehensive metadata models are deployed to document information on an object’s context. Yet, we claim that simply documenting an objects context may not be sufficient to ensure pr...

Digital Video Archives

In this paper we discuss the role that a video data base may play in a digital video archive and some of the challenges that video data bases are facing Prob lems related to large scale storage and delivery of video data are brie y discussed while a modelling and query ing aspecs are treated more thoroughly We propose a generic data model that captures video data struc tures and that supports t...

Digital Archives and Preservation

DEFINITION Preservation is the set of processes that maintain the authenticity, integrity, and chain of custody of records for long periods of time. Authenticity is defined as the management of provenance information about the creation of the record. Integrity is defined as the ability to create an authentic copy. Chain of custody tracks all processing done to the record, including migration to...

XML Retrieval for Digital Archives

Using digital spatial archives effectively

The size and complexity of modern geographic datasets continue to grow and with that growth comes an increased difficulty in assessing the usefulness of a particular dataset for a particular problem. The task of browsing through a large database is rapidly becoming impractical because of the shear volume of the data, therefore, the information potential of the database is lost because the scope...
