چکیده

Emulation has evolved into a mature digital preservation strategy providing, inter alia, functional access to a wide range of digital objects using their original creation environments. In contrast to format migration strategies a functional, emulation-based approach requires a number of additional components. These can be provided by Emulation-as-a-Service, implemented and developed as a distributed framework for various emulation-based services and technologies for long-term preservation and access. This paper presents three distinct applications of the emulation-strategy to preserve complex scientific processing systems, to render complex interactive and dynamic digital objects, and to implement a universal migration-workflows utilizing the original environments in which objects were created.

Adding Quality-Awareness to Evaluate Migration Web-Services and Remote Emulation for Digital Preservation

Digital libraries are increasingly relying on distributed services to support increasingly complex tasks such as retrieval or preservation.While there is a growing body of services for migrating digital objects into safer formats to ensure their long-term accessability, the quality of these services is often unknown. Moreover, emulation as the major alternative preservation strategy is often ne...

Rainfall-runoff modelling using artificial neural networks (ANNs): modelling and understanding

In recent years, artificial neural networks (ANNs) have become one of the most promising tools in order to model complex hydrological processes such as the rainfall-runoff process. In many studies, ANNs have demonstrated superior results compared to alternative methods. ANNs are able to map underlying relationship between input and output data without prior understanding of the process under in...

Emulation & Virtualization as Preservation Strategies

Between the two fundamental digital preservation strategies, migration has been strongly favored. Recent developments in emulation frameworks make it possible to deliver emulations to readers via the Web in ways that make them appear as normal components of Web pages. This removes what was the major barrier to deployment of emulation as a preservation strategy. Barriers remain, the two most imp...

Modular emulation as a long-term preservation strategy for digital objects

The use of emulation as a preservation strategy is often looked upon with skepticism. Although it may be the only way to render digital objects authentically in the future, emulation is thought to be too technically challenging and therefore too expensive and time-consuming. This line of thought has thus far prevented emulation from being developed for preservation purposes. However, the Nation...
