Editing the data usually requires the prior coding ¹ of a certain number of entries on the basic document ². The coding scheme ³ establishes a correspondence between an entry and its translation into numeric or alphabetic codes. The code book collects and describes the coding schemes used with a particular set of basic documents. A coding scheme is usually designed to facilitate later groupings of the data. In contrast, a classification ⁴ is a mere list of individual codes where each heading ⁵ is given one or several numbers. After the data have been coded, they constitute a file (213-3*) which can be converted to machine readable form. The second stage in the editing consists in the cleaning ⁶ of the file, through elimination of errors by validity checks ⁷ and consistency checks ⁷; these can be internal checks within each statistical unit (cf. 110-1) or may result from the comparison of different units. After errors have been identified, they may be corrected in the original document or the file by some automatic procedure.
