The content provider should include the following fields as columns in the tabseparated metadata file. All fields should be considered to be mandatory if they exist, and all effort should be made to gather the data, even if it must be obtained from another area of the business or even from an external source. Because recipients of metadata files will be expecting to receive all files in a matching format, every field should appear in the order given below, even if the content provider is unable to provide any information, or no information is appropriate for a specific field. The following field labels should be used. To avoid confusion and unnecessary errors, content providers are encouraged to include labels on every file they generate.

For consistency, the following labels should be used. Examples of complete records for various types of content are given in Appendix A: Data Exchange Samples (.xls).
