The whole list has been revisited on 2010-10-22, and numerous changes to urls have been made. Really foundational materials have been saved as local copies, attached to this page.

CASPAR

Cultural, Artistic and Scientific knowledge for Preservation, Access and Retrieval - an Integrated Project co-financed by the European Union within the Sixth Framework Programme, that started on 1 April 2006.

DELOS

Network of Excellence on Digital Libraries partially funded by the European Commission in the frame of the Information Society Technologies Programme (IST). The main objectives of DELOS are research, whose results are in the public domain, and technology transfer, through cooperation agreements with interested parties.

On cluster of the programme (WP6) is dedicated to digital preservation issues. Integrated research in the preservation cluster will provide the methodological framework and theory for ensuring that digital libraries research addresses preservation issues and digital libraries incorporate preservation elements in their designs.

SIARD

Project and toolkit by the Swiss Federal Archives. When we started MIXED we only had limited information at our disposal. At the end of MIXED we decided to prefer the SIARD format for databases over the format we had adopted during the project, which was e-David.

Typed Object Model. A networked service to document information types. Moreover: a system of conversions between information types. Clients can look for conversion services through type brokers. A completely different approach to digital durability than MIXED tries to implement. The original link TOM cannot be followed (2010-10-22), it is mentioned still at GDFR: "TOM is a data model for describing a wide variety of data types and formats. In a broader sense, the term "TOM" is also used to describe a supporting architecture built around mediator agents called "type brokers", that receive and maintain descriptions of data formats, describe them to clients, and contact servers that interpret and translate data in those formats."

A Proposed Standard for the Scholarly Citation of Quantitative Data. By Micah Altman, Gary King. The interesting topic for MIXED here is UNF (Universal Numeric Fingerprints). This is a technology to take fingerprints from tabular data; the fingerprints are sensitive to the values of the data, not to the file format of the data. MIXED may use UNFs to test whether a format conversion preserves the actual data faithfully, an important quality check.
