Digital Preservation as a Science
Digital Preservation is a domain within ICT, that is mainly based on empirical knowledge. One way to introduce theoretical fundamentals is to study accumulated experience and best practices, and expose a common framework from them. In this paper, an idea of having metrics as common objective assessment of capabilities of tools, environments and processes is described. The goal is to have DP wel...
متن کاملThe role of science in the preservation of forest biodiversity
Forest management must change radically to maintain biodiversity. `Biodiversity' has many components, but only one has been measured unambiguously ± species richness ± although there is recently much emphasis on structural, process, and functional diversity. So we must determine exactly what aspects of biodiversity to seek, and why. A battery of suggestions about how to achieve this re-focus on...
متن کاملDigital Preservation in Data-Driven Science: On the Importance of Process Capture, Preservation and Validation
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...
متن کاملThe basic science aspect of donor heart preservation: a review.
In cardiac transplantation, the transport time between harvest and recipient is limited by the viability of the donor heart. The problem of viability is a consistent limitation in cardiac transplantation. Since the 1960s, techniques, including hypothermia, perfusion, oxygenation, and hyperbaria, have been used to prolong the preservation of the transplantable heart. Continuing development of ca...
