Other Study-Related Materials

This section allows for the inclusion of other materials that are related to the study as identified and labeled by the DTD/Schema users (encoders). The' materials may be entered as PCDATA (ASCII text) directly into the document (through use of the "txt" element). This ection may also serve as a "container" for other electronic materials such as setup files by providing a brief description of the study-related materials accompanied by the attributes "type" and "level" defining the material further. The "URI" attribute may be used to indicate the location of the other study-related materials.

Other Study-Related Materials may include: questionnaires, coding notes, SPSS/SAS/Stata setup files (and others), user manuals, continuity guides, sample computer software programs, glossaries of terms, interviewer/project instructions, maps, database schema, data dictionaries, show cards, coding information, interview schedules, missing values information, frequency files, variable maps, etc.

The "level" attribute is used to clarify the relationship of the other materials to components of the study. Suggested values for level include specifications of the item level to which the element applies: e.g., level= data; level=datafile; level=studydsc; level=study. The URI attribute need not be used in every case; it is intended for capturing references to other materials separate from the codebook itself. In Section 5, Other Material is recursively defined.
