Many digital preservation scenarios are based on the migration strategy, which itself is heavily tooldependent. For popular, well-defined and often open file formats – e.g., digital images, such as PNG, GIF, JPEG – a wide range of tools exist. Migration workflows become more difficult with proprietary formats, as used by the several text processing applications becoming available in the last tw...

zona pellucida, the theca interna and in atretic follicles (Porter, 1965; Porter, Highfill & Winovich, 1970a, b; Ownby & Shivers, 1972; Sacco & Shivers, 1973a, b, c, d). Antisera (by precipitate formation) modified the surface of the zona pellucida of hamster and rabbit ova to such an extent that it even became inert to the lytic effects of trypsin (Ownby & Shivers, 1972; Sacco & Shivers, 1973a...

This paper explores a new way of thinking about digital preservation and introduces a new requirement for interoperability that I refer to as temporal interoperability. The concept of temporal interoperability concerns the interoperability of systems and the access to heterogeneous collections over time. The paper discusses recent developments in digital preservation that begin to approach pres...

Until now, information retrieval (IR) managers have been absorbed by efforts to increase the amount and quality of scholarly deposits. Other pressing concerns have been to develop the software, standards, and other tools to insure access, exchange, and discovery of the works in the IRs. But building an IR without making plans for technological, organizational, and resourcing sustainability is l...

An unprecedented amount of digital information, appearing on a daily basis, needs to be archived and preserved over long time periods. Such information covers major facets of human activities such as business exchanges and electronic commerce, cultural and social interactions, e-government and legal proceedings, scientific studies and data collections, and even personal data such as digital pho...

Digital curation micro-services offer a light-weight alternative to preservation systems that are developed on digital repository and framework technology stacks. These are often too complex for small and medium-sized memory institutions to deploy and maintain. The Archivematica project has implemented a micro-services approach to develop an integrated suite of free and open-source tools that a...

The National Library of the Netherlands (KB) will renew its digital archiving environment. The current system, the e-Depot with DIAS by IBM as its technical core, has been operational since 2003 and needs to be updated. More importantly, a new system is required because KB has published a new strategic plan with ambitious goals. They require development of an infrastructure that can process, st...

Funded by the National Digital Information Infrastructure and Preservation Program (NDIIPP), the ECHO DEPository Project supports the digital preservation efforts of the Library of Congress by contributing research and software to help society GET, SAVE, and KEEP its digital cultural heritage. Project activities include building Web archiving tools, evaluating existing repository software, deve...

The term “digital repository” is used in disparate contexts, in both in a formal sense to describe a complex and complete preservation system and its policies, and in a more intuitive but less clearly defined sense, often implying simply a robust storage system, or a content management system. Lack of formalism in use of this term can impede development of formal requirements for building speci...
