History
DFDL was created in response to a need for grid APIs to be able to understand data regardless of source. A language was needed capable of modeling a wide variety of existing text and binary data formats. A working group was established at the Global Grid Forum (which later became the Open Grid Forum) in 2003 to create a specification for such a language.
A decision was made early on to base the language on a subset of W3C XML Schema, using
Work continued on the specification, culminating in the publication of DFDL 1.0 as an OGF Proposed Recommendation in January 2011. A summary of DFDL and its features is available at the OGF site. Any issues with the specification are being tracked in an errata document. The first chapters of a DFDL Tutorial are also available.

Famous quotes containing the word history:
“We don’t know when our name came into being or how some distant ancestor acquired it. We don’t understand our name at all, we don’t know its history and yet we bear it with exalted fidelity, we merge with it, we like it, we are ridiculously proud of it as if we had thought it up ourselves in a moment of brilliant inspiration.”
—Milan Kundera (b. 1929)
“The history of all previous societies has been the history of class struggles.”
—Karl Marx (1818–1883)
“The only history is a mere question of one’s struggle inside oneself. But that is the joy of it. One need neither discover Americas nor conquer nations, and yet one has as great a work as Columbus or Alexander, to do.”
—D.H. (David Herbert)
