An enhanced publication is a publication that is enriched with three categories of information:
1. research data (evidence of the research)
2. extra materials (to illustrate or clarify)
3. post-publication data (commentaries, ranking)
Enhanced Publication components
The parts of an enhanced publication should be selected carefully. Publishers and repositories should set up a checklist for objects forming part of an enhanced publication. More specifically objects should have:
1. a unique global persistent identifier;
2. a facility for the link to be resolved;
3. a time stamp;
4. a common file type (for future use);
5. a universal numeric fingerprint for data sets;
6. “Cite as” information;
7. a quality good enough for preservation; and
8. it should be legal to publish the object.
The first Keeping Research Data Safe study funded by JISC made a major contribution to the study of preservation costs by developing a cost model and indentifying cost variables for preserving research data in UK universities. That work has had considerable impact and received international interest. Over 3,400 copies of the report were downloaded from the JISC website during 2008 alone making it JISC's most popular publication in 2008.
The Keeping Research Data Safe 2 project commenced on 31 March 2009 and will complete in December 2009. The project will identify and analyse sources of long-lived data and develop longitudinal data on associated preservation costs and benefits. We believe these outcomes will be critical to developing preservation costing tools and cost benefit analyses for justifying and sustaining major investments in repositories and data curation.
