[Classification of the CNPq areas of knowledge and the nursing field: possibilities and limits].

Knowledge areas have been discussed by Science and Technology managers and administrators and by the scientific community searching for tools to support data systematization, mainly for management and administrative activities. The main table in use by CNPq is admittedly outdated and requires revision or reclassification. The aim of this article is to contribute to the current debate based on previous results from participation in a table review study performed in the 1990 s and on research results in the area of knowledge organization and representation in the context of Information Science. It presents a proposal to reformulate the Nursing Knowledge Area and some reflections about the possibilities of this ongoing process.
