Distributable Educational Material Markup LanguageTM


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.

Creating the Hierarchical Tree of Knowledge

Before all of these code numbers can be assigned to all of these branches on this incredibly large tree of knowledge there is one very important piece that is still missing. The tree itself. Naturally, the LCC classification system is clearly defined. However, there is still a lot of detail left to be filled in. It would almost be possible for one person to sort out many of these details simply by sitting down with a stack of textbooks from each of the academic disciplines and listing the names of all the chapters, sections, and topics. However, this would not be appropriate. The section of the tree for each discipline should be created by experts in each of these fields, not by someone who simply knows how to created complicated coding systems. This section outlines the work that will be necessary to find and gather the appropriate experts in each discipline, convince them that DEMML™ is worth an investment in their time, and help them to create a tree of all the subjects and topics in their disciplines which is detailed enough to be useful within DEMML™.

The first step is to sort out what all the different academic disciplines are called. This may sound simple but different universities have different ideas of how these disciplines should be divided, grouped, and named. And the Library of Congress has its own ideas which may or may not mesh with what universities think. Experts will need to be consulted and a consensus will need to be built for each and every division.

Many academic disciplines have professional associations or organizations which promote their discipline and oversee how they are taught. These associations will prove invaluable in sorting out the necessary details. So, after all the disciplines have been listed, the associations for all these disciplines will need to be found and contacted. It may take some work to convince all of these organizations to help with the project. But once some have, it should be easier to convince others to get involved. Unfortunately, in many instances, there is more than one group who claims to be "The" arbiter of all things involved with their discipline. So, once again, consensus will need to be built and final decisions will need to be made.

Some disciplines have already developed hierarchical trees of subjects within their fields. While these lists will provide a great starting point, none of them have the level of detail needed for DEMML™. It will require quite a bit of back and forth dialog to finalize these details in a way that will work best with DEMML™.

As a final step to help sort out the level of detail necessary, we will survey and consult with students to uncover the little things that teachers and association directors often take for granted. This step alone will be an incredibly large and ongoing project. To be as complete as possible, students at all levels, from grade-school to doctorate, will need to be surveyed.

Rather than attempt to do everything at once it will probably be best to focus on one or two disciplines and work them to completion. Once the trees for those disciplines are fully developed then content can start being put into the system. Once content is in the system and useable then more people will start to see the benefit of using DEMML™. This will make it much easier to get others to contribute their time and knowledge. As more contribute, the system will become more useful and more well known. Once the momentum begins to build, it will not be long before a tipping point is reached and everyone will want to get involved.
