This document is the final description of the work with revising the Nomenclature for the Analysis and Comparison of Scientific Programmes and Budgets (NABS) of 1992 version into the 2007 version and provides a comparison between the two versions. It further contains, as annexes, the final version of the NABS 2007 chapter and sub-chapter headings, the final version of NABS 2007 including the detailed annotations as well as a detailed bridge table between NABS 2007 and NABS 1992. The classification is linked to the Frascati Manual (OECD 2002). The area of socio-economic objectives (SEO) of research and development (R&D) activities is considered in two ways in the Frascati Manual. The first is as a functional classification of the performance of R&D and the second relates to the analysis of government appropriations to R&D (GBOARD). The body responsible for the NABS classification is Eurostat. The NABS nomenclature was originally established in 1969 and earlier revisions were carried out in 1975, 1983, 1992 and recently in 2007.
