A Formal Approach to the Modelling of Digital Archives [chapter]

Rathachai Chawuthai, Vilas Wuwongse, Hideaki Takeda
2012 Lecture Notes in Computer Science  
Therefore, in order to help users understand digital archives precisely, an archival system should preserve its resources along with their underlying community knowledge, and support the interpretation  ...  This research presents a formal approach to digital archives including ontology for preserving the evolution of contextual knowledge.  ...  This approach is built upon Semantic Web technology, which results in an ability for computers and machines to read and understand data.  ...

Data Grids, Digital Libraries, and Persistent Archives: An Integrated Approach to Sharing, Publishing, and Archiving Data

R.W. Moore, A. Rajasekar, M. Wan
2005 Proceedings of the IEEE  
We examine the synergies between these data management systems and the future evolution that is required for the generation and management of information.  ...  The integration of grid, data grid, digital library, and preservation technology has resulted in software infrastructure that is uniquely suited to the generation and management of data.  ...  This approach works very well for building scientific data collections, for sharing data within an organization, and for publishing data on the Web.  ...

Introduction to the focussed issue on Semantic Digital Archives

Thomas Risse, Livia Predoiu, Annett Mitschick, Andreas Nürnberger, Seamus Ross
2015 International Journal on Digital Libraries  
As soon as these digital materials, whether they be publications, data sets, or records of transactions, become obsolete, but are still deemed to be of value in the future, they have to be transferred  ...  smoothly into appropriate archival information systems (AIS) where they can be kept accessible against a backdrop of changing technologies, information practices, and documentation standards.  ...  An Open Linked Data architecture for maintaining historical archives is proposed in the paper "A linked open data architecture for the historical archives of the Getulio Vargas Foundation".  ...
