The first edition of the OECD Frascati Manual, the international standard on collecting resources devoted to research and development (R&D), was released in 1963. The same year, the first Development Assistance Committee (DAC) Recommendation on Financial Terms and Conditions was agreed, setting out initial conditions for what later would become official development assistance (ODA). The definitions, statistical standards, and reporting directives of these concepts have since evolved through discussions and agreements within their own policy communities.
