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.
