The Directory Interchange Format (DIF) is a data structure used to exchange
directory-level information about data sets among information systems. In
general, the format consists of a number of fields that describe the attributes of
a directory entry and text blocks that contain a descriptive summary of and
references for the directory entry. All fields and the summary are preceded by
labels identifying their contents. All values are ASCII character strings. The
structure is intended to be flexible, allowing for future changes in the contents
of directory entries.

This manual describes what constitutes a directory entry and the content of
the individual fields within the data structure, along with some examples.
