Editing Dataphor (section)

===Frontend Library===
The Dataphor Frontend library provides for the delivery of dynamically derived, or pre-designed static forms.  The library is exposed as a standard set of D4 functions (called operators in D4) such as Form ('{{var|library}}', '{{var|name}}') and Derive ('{{var|D4 expression}}', '{{var|form type}}').  The resulting forms are described in an [[XML]] dialect called a Dataphor Form Document (DFD).  The form description is high-level, consisting of a general description of the user interface aspects as they apply independent of client platform.
