The Research Information Network (RIN) has published Stewardship of Digital Research Data: A Framework of Principles and Guidelines: Responsibilities of Research Institutions and Funders, Data Managers, Learned Societies and Publishers.
Here's an excerpt from the Web page describing the document:
Research data are an increasingly important and expensive output of the scholarly research process, across all disciplines. . . . But we shall realise the value of data only if we move beyond research policies, practices and support systems developed in a different era. We need new approaches to managing and providing access to research data.
In order to address these issues, the RIN established a group to produce a framework of key principles and guidelines, and we consulted on a draft document in 2007. The framework is founded on the fundamental policy objective that ideas and knowledge, including data, derived from publicly-funded research should be made available for public use, interrogation, and scrutiny, as widely, rapidly and effectively as practicable. . . .
The framework is structured around five broad principles which provide a guide to the development of policy and practice for a range of key players: universities, research institutions, libraries and other information providers, publishers, and research funders as well as researchers themselves. Each of these principles serves as a basis for a series of questions which serve a practical purpose by pointing to how the various players might address the challenges of effective data stewardship.
