First Alpha version of schema published.

Though it is still rough and only covers the fundamental constituents of a DEMML™ topic, the DEMML_0.1 schema is available for viewing here.

Created DEMML™ blog site.

It took me a while to get around to creating a blog but it is finally up. (Updated July 8, 2009)

Added new Features and Benefits page.

DEMML is truely unique but I seem to have a hard time getting people to see that. Hopefully this will help. (Updated Dec. 10, 2007)

How DEMML™ was Invented

Necessity truly is the mother of invention.

Welcome to the home of™

This site describes and promotes the DEMML™ standard and associated systems.

What is the Distributable Educational Material Markup Language™?

The Distributable Educational Material Markup Language™ (DEMML™) is both an XML format for marking up educational material in a highly structured yet incredibly flexible manner and a system for authenticating and distributing that content for independent or shared use throughout the world, even where there is no internet connection. This material is organized and classified to a degree never before attempted, using what turns out to be a rather simple system of encoding the hierarchical tree of all possible educational material right down to the paragraph - or even sentence - level. This allows anyone to easily contribute any amount of material to what will quickly grow to be a vast library of vetted content for all to use. In addition, the format facilitates a new level of flexibility in computer based learning by allowing educators to specify what material the student should study while still allowing the student instant access to additional, alternative material as their needs require. Multiple different explanations or presentations can exist for any one fact within any very specific topic. This allows any student at any level to quickly find just the right explanation that helps them most efficiently understand the topic at hand.

DEMML™ is not yet another Computer Based Training (CBT) system. Instead, it is a way of creating a library of educational material in a standardized format which all compatible CBT systems can instantly draw from, with no manual editing whatsoever. Existing CBT software can be modified slightly to make use of this content or modified even further to employ the rich functionality that only DEMML™ provides - facts, multiple alternate explanations, questions and answers, problems and solutions, multiple alternate explanations for each of those, prerequisites, etc., with very rich metadata about everything. Just as hyperlinking existed long before Tim Berners-Lee invented the World Wide Web and HTML, CBT has been around a long time before DEMML™. Before HTML all hyperlinking systems were proprietary and only worked within limited confines. Similarly, current CBT systems are all either proprietary systems or are relatively unavailable to the public. DEMML™ will be to CBT what HTML and WWW have been to hyperlinking.

To be clear, DEMML™ is not intended to replace all the other educational content libraries that already exist. Instead, it will provide a means to organize them all into one distributed system and direct students to the exact right content at the exact right time. So, instead of competing with other content libraries, DEMML™ will promote their use and make them more effective. It will open up a world of possibilities by making all educational content easily available to everyone, everywhere.

“Only when students can easily obtain and master all the material necessary for a course of study entirely on their own will they be free of the barriers that stand between them and knowledge. Only when everyone in the world has free and easy access to all the education they want or need will we be able to overcome the suffering created when the uneducated are left to fend for themselves against the unscrupulous.”
