It is universally acknowledged that researchers are interested in data of all kinds, regardless of origin or type.

Here are some of the recognised definitions of research data:

“Research data, unlike other types of information, is collected, observed, or created, for purposes of analysis to produce original research results.” Edinburgh University Data Library Research Data Management Handbook  

“Research data means data in the form of facts, observations, images, computer program results, recordings, measurements or experiences on which an argument, theory, test or hypothesis, or another research output is based. Data may be numerical, descriptive, visual or tactile. It may be raw, cleaned or processed, and may be held in any format or media”. The Queensland University of Technology Management of Research Data Policy

“The recorded information (regardless of the form or the media in which they may exist) necessary to support or validate a research project’s observations, findings or outputs”. The University of Oxford Policy on Management of Research Data and Records

In addition to research data, research data management also covers managing of research records both during and beyond the life of a project. Examples of such research records include:

• Correspondence (electronic mail and paper-based correspondence)
• Project files
• Grant applications
• Ethics applications
• Technical reports
• Research reports
• Signed consent forms
