DDI-Codebook v1.x

Structured, descriptive documentation of the content, meaning, provenance, and access for a single data set. Originally developed as an XML DTD, Codebook retains the hierarchical structure of a DTD in describing the contents of a descriptive codebook for a data set including identification, authorship, ownership, purpose, background methodologies, source information, provenance, quality control, access, physical file structures, variables/variable groupings, and related materials. Extensive information is found within the variable description covering the data source, derivation activity, representation, data typing, variable role, and restrictions.
