Transparent Format Migration of Preserved Web Content

David S. H. Rosenthal, Thomas Lipkis, Thomas S. Robertson, Seth Morabito
2005 D-Lib Magazine  
We describe the design and implementation of a transparent, on-access format migration capability for the LOCKSS system for preserving Web content. [LOCKSS is a trademark of Stanford University.  ...  The LOCKSS program has designed and tested an initial implementation of format migration for Web content that is transparent to readers, building on the content negotiation capabilities of HTTP.  ...

Transparent Format Migration of Preserved Web Content [article]

David S. H. Rosenthal, Thomas Lipkis, Thomas Robertson, Seth Morabito
2004 arXiv   pre-print
The LOCKSS program has designed and tested an initial implementation of format migration for Web content that is transparent to readers, building on the content negotiation capabilities of HTTP.  ...  The LOCKSS digital preservation system collects content by crawling the web and preserves it in the format supplied by the publisher. Eventually, browsers will no longer understand that format.  ...  Any opinions, findings, and conclusions or recommendations expressed here are those of the authors and do not necessarily reflect the views of these funding agencies.  ...

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

Christoph Becker, Hannes Kulovits, Michael Kraxner, Riccardo Gottardi, Andreas Rauber, Randolph Welte
2009 Lecture Notes in Computer Science  
This paper presents a preservation action monitoring infrastructure that combines provider-side service instrumentation and quality measurement of migration web services with remote access to emulation  ...  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.  ...  Acknowledgements Part of this work was supported by the European Union in the 6th Framework Program, IST, through the PLANETS project, contract 033789.  ...

Migration to Intermediate XML for Electronic Data (MIXED): Repository of Durable File Format Conversions

René Van Horik, Dirk Roorda
2011 International Journal of Digital Curation  
The features of the intermediate XML files are stored in the so-called Standard Data Formats for Preservation (SDFP) specification.  ...  Smart migration concerns the conversion upon ingest of specific kinds of data formats, such as spreadsheets and databases, to an intermediate XML formatted file.  ...  Thus, a smart method of migration is to migrate to data formats expressed in XML, not to a newer version of a non-transparent format.  ...

Rethinking Personal Digital Archiving, Part 2

Catherine C. Marshall
2008 D-Lib Magazine  
The Library of Congress is drafting a decision-support framework pertaining to the preservation of digital content.  ...  The framework is presented through a Web site that identifies and documents digital content formats that are promising (or unpromising) for long-term sustainability, together with some explanatory essays  ...  We believe that these factors will be significant whether preservation strategies entail future migration to new formats, emulation of current software on future computers, a hybrid of migration and emulation  ...

Ensuring the Longevity of Digital Documents.  ...  Preemptive migration on input is often called normalization. All such systems of which we are aware plan to preserve the original format; some in addition preserve the result of format migration.  ...

Plato

Christoph Becker, Hannes Kulovits, Andreas Rauber, Hans Hofman
2008 Proceedings of the 8th ACM/IEEE-CS joint conference on Digital libraries - JCDL '08  
Different strategies such as migration and emulation have been proposed; however, the decision for a specific tool e.g. for format migration or an emulator is very complex.  ...  The process of evaluating potential solutions against specific requirements and building a plan for preserving a given set of objects is called preservation planning.  ...  Acknowledgements Part of this work was supported by the European Union in the 6th Framework Program, IST, through the PLANETS project, contract 033789.  ...

Requirements for Digital Preservation Systems: A Bottom-Up Approach [article]

David S. H. Rosenthal, Thomas S. Robertson, Tom Lipkis, Vicky Reich, Seth Morabito
2005 arXiv   pre-print
The field of digital preservation is being defined by a set of standards developed top-down, starting with an abstract reference model (OAIS) and gradually adding more specific detail.  ...  We develop a parallel set of requirements based on observations of how existing systems handle this task, and on an analysis of the threats to achieving the goal.  ...  Any opinions, findings, and conclusions or recommendations expressed here are those of the authors and do not necessarily reflect the views of these funding agencies.  ...

An intelligent decision support system for digital preservation

Miguel Ferreira, Ana Alice Baptista, José Carlos Ramalho
2007 International Journal on Digital Libraries  
This paper describes a Service Oriented Architecture (SOA) based on Web services technology designed to assist cultural heritage institutions in the implementation of migration based preservation interventions  ...  Although the primary goal of this SOA is the implementation of migration based preservation interventions, it can also be used for other purposes such as comparing file formats or evaluating the performance  ...  Transparency support Whether the format offers transparency features. This criterion is somewhat specific to certain types of formats (e.g. raster images).  ...
