Representation Information: what is it and why is it important?

Representation Information is a key and often misunderstood concept. To understand it, we need to look at some definitions. First of all, OAIS (CCSDS 2002) defines data thus:“Data: A reinterpretable representation of information in a formalized manner suitable for communication, interpretation, or processing.”Second, we have Information:

Authenticity across migrations

I discovered a few days ago that I have 4 digital objects that are (I believe, but am not certain) in some strong senses “the same” (in their information content), but which are also completely different (in their bits). These objects are the result of a chain of “exports” and “imports”, and “save as…” operations, prompted partly by a change of technology (from a Windows PC running Mind Manager to a Macintosh running NovaMind), and partly from a need to make the content of the object more accessible to colleagues who do not use either software package.

OECD Principles and Guidelines for Access to Research Data

Drafts of the OECD’s Principles and Guidelines for Access to Research data from Public Funding (OECD, 2007) have been available for some time, and the final Recommendation was approved in December 2006. I have only recently had the chance to read the report that details and explains this recommendation. This is a very important document, which could have a major effect on our scientific information systems.The arguments they put forward in support of the Recommendation are powerful:

Building expertise in digital curation and preservation

It’s curious when something new has been around for 30 years or so. However, that’s the paradoxical case with digital curation. The term itself is relatively new, and there is still (as usual) confusion as to what exactly it means. But taking the simple definition (maintaining and adding value to a trusted body of digital information over the life-cycle of scholarly and scientific materials, for current and future use), it is clear that some disciplines have had organisations doing this for many years.

JISC Repositories conference day 2

This is a rather late posting about day 2 of the JISC Repositories Conference, a week or so ago now. I mainly attended the data-oriented stream. I was very interested in the presentations from the StORe and CLADDIER projects, both of which touched on data citation. They go about this in different ways.

Arts and Humanities Data Service decision

On 14 May 2007, the UK Arts and Humanities Research Council (AHRC) issued a rather strange press release, announcing that “AHRC Council has decided to cease funding the Arts and Humanities Data Service (AHDS) from March 2008” and at the same time announcing a change to its conditions of grant relating to deposit, removing the condition that material be offered for deposit in AHDS, although “Grant holders must make materials they had planned to deposit with the AHDS available in an accessi

JISC Repositories conference day 1

Yesterday and today I am at the JISC Repositories Conference in Manchester. This turns out to be (at least in my small section, and the two plenaries so far) a much more interesting event than I expected. There has been a useful focus on the fringes of the repository movement, such as the role of data, and as well an interesting re-exploration of what repositories are, and what they are for.

Supplementary Material in journal publishing

I went to a couple of interesting events in March and April. The first was the eJournal Archiving & Preservation Workshop held at the British Library on 27 March, 2007 (sponsored by the Digital Preservation Coalition, BL and JISC).

Life cycle approach

Digital Curation is maintaining and adding value to a trusted body of digital information over the life cycle of scholarly and scientific materials, for current and future use. It is our belief in the DCC that the curation of digital data requires this whole of life approach. Critical decisions on the curation of data are taken before the data are even created, often at the time the associated project is conceived, or funding is sought. This is not least because curation requires resources that must be allowed for within the work plan.

Introduction to the Digital Curation Blog

The Digital Curation Centre runs a Forum for its Associate Network community, based on bulletin board technology (see http://forum.dcc.ac.uk/). This exercise has been a limited success; although we have many Associates Network members, and some considerable traffic reading the Forum, there has not been a substantial and frequent posting, and overall most posts have been from DCC staff. The Forum has been comparatively successful compared with some other such ventures in the JISC community, but its success has not satisfied us.
