Accessible graphics

While reading eQuality (by Peter Blanck) I came across a reference to "Diagrammar: A Framework for Making Images and Graphics Accessible" (actually to its immediate predecessor):

http://diagramcenter.org/standards-and-practices/content-model.html

I expect that several of you may already be familiar with this, but it was something new to me - and it seemed to fit well with many of the issues we have been addressing. For example, the framework already allows for multiple forms of both the image and of the associated descriptive text (i.e. you can have simplified versions of both of these).

Such a framework seems to be just what is needed to allow a personalization mechanism to deliver the appropriate levels of content to meet the cognitive abilities of the individual user.

Best regards
