Data archiving in animal experimentation: merits, challenges, and a case study.

Electronic data archives may supplement the traditional peer-reviewed journal article. The merits of data archiving include public service, a more complete research project, overcoming barriers to limited-access research resources, and increasing the impact of a scientific project. A case study of chimpanzee timing performance in space is derived from the NASA Life Sciences Data Archive (http://lsdajsc. nasagov). An analysis of the archived data suggests that the scalar property (a form of Weber's law) applies to timed performance of a chimpanzee in orbit of the earth. Challenges associated with data archives are discussed. Although significant challenges are associated with archiving electronic data, these difficulties are outweighed by its merits.
