Data Format Description Language (DFDL, often pronounced daff-o-dil) is a modeling language from the Open Grid Forum for describing general text and binary data. A DFDL model or schema allows any text or binary data to be read (or "parsed") from its native format and to be presented as an instance of an information set. The same DFDL schema also allows data to be taken from an instance of an information set and written out (or "serialized") to its native format.

DFDL achieves this by building upon the facilities of W3C XML Schema 1.0. A subset of XML Schema is used, enough to enable the modeling of non-XML data. One of the results of this is that is very easy to use DFDL to convert general text and binary data, via a DFDL information set, into a corresponding XML document.

It is important to note that DFDL is descriptive and not prescriptive. DFDL is not a data format, nor does it impose the use of any particular data format. DFDL allows an application to design an appropriate data representation according to its requirements, and for that format to be described in a standard way so that multiple programs can directly interchange the data.
