What Are Data? The Many Kinds of Data and Their Implications for Data Re-Use
Added 9 February 2007
http://jcmc.indiana..../issue2/carlson.html
authors - Samuelle Carlson & Ben Anderson
One key feature of e-science is to encourage archiving and release of data so that they are available in digitally-processable forms for re-use almost from the point of collection. This assumes particular processes of translation by which data can be made visible in transportable and intelligible forms. It also requires mechanisms by which data quality and provenance can be trusted once "disconnected" from their producers. By analyzing the "life stages" of data in four academic projects, we show that these requirements create difficulties for disciplines where tacit knowledge and craft-like methods are deeply embedded in researchers, as well as for disciplines producing non-digital heterogeneous data or data derived from people rather than from material phenomena. While craft practices and tacit knowledges are a feature of most scientific endeavors, some disciplines currently appear more inclined to attempt to formalize or at least record these knowledges. We discuss the implications this has for the e-science objective of widespread data re-use.

White Paper: "Representation Information Registries"
Added 17 March 2008
http://www.planets-p...mationRegistries.pdf
This document is a report on the state-of-the-art in the field of Representation Information Registries (RIRs). RIRs are widely recognised as a critical component of digital preservation architecture in general, and a number of such registries are being developed as part of the Planets architecture in particular. This document discusses the development of the concept of representation information, and of the use of registries as a means of exposing that information for use by digital preservation services; it describes the RIR implementations which currently exist or are under development globally; it assesses planned and potential future developments in this area; it discusses the role which RIRs play within the Planets project, and concludes with recommendations for future areas of research within Planets and beyond.
