Description:
Information about the data file(s) that comprises a collection. This section can be repeated for collections with multiple files.
The "URI" attribute may be a URN or a URL that can be used to retrieve the file. The "sdatrefs" are summary data description references that record the ID values of all elements within the summary data description section of the Study Description that might apply to the file. These elements include: time period covered, date of collection, nation or country, geographic coverage, geographic unit, unit of analysis, universe, and kind of data. The "methrefs" are methodology and processing references that record the ID values of all elements within the study methodology and processing section of the Study Description that might apply to the file. These elements include information on data collection and data appraisal (e.g., sampling, sources, weighting, data cleaning, response rates, and sampling error estimates). The "pubrefs" attribute provides a link to publication/citation references and records the ID values of all citations elements within Other Study Description Materials or Other Study-Related Materials that pertain to this file. "Access" records the ID values of all elements in the Data Access section that describe access conditions for this file.
Remarks: When a codebook documents two different physical instantiations of a data file, e.g., logical record length (or OSIRIS) and card-image version, the Data File Description should be repeated to describe the two separate files. An ID should be assigned to each file so that in the Variable section the location of each variable on the two files can be distinguished using the unique file IDs.
