Data Format Description Language (DFDL) 1.0 is a modeling language from the Open Grid Forum that is used to define the structure of general text and binary formatted data in a way that is independent of the data format. It is based on XML Schema 1.0.
DFDL is not intended to be used to model XML documents. Use normal XML Schema files to model XML.
For more
information about DFDL, see the Open Grid Forum (OGF) website.
A
navigable copy of the DFDL v1.0 Specification is included
with this information. The latest published specification is on the
OGF website, in HTML and PDF formats. The specification is produced
by the OGF DFDL Working Group. The specification is an OGF Proposed
Recommendation; see the OGF document repository for any published
errata.
The OGF document repository also contains a DFDL tutorial,
comprising a number of PDF files. IBM have
several DFDL modeling scenarios available on developerWorks®.
