AP: If it's not visible, to whom is it useful anyway?

CS: It can be used by assistive technologies designed for this group of
users, much like alt text is used by screen readers.  Alt text is not
normally visible either, but it is standardized metadata (of a sort) that
works with the assistive technology used by blind users -- the screen

One possible assistive technology would be browser add-on that showed the
summary instead (or ahead) of the non-alternative content.  Hidden metadata
about a page can also be used by search engines and indexing services, so
that you could, for example, search for information about George Washington
written to a 3rd grade reading level.  Another browser add-on could
automatically filter all searches for appropriate reading level.  I'm sure
there are others too, but you get the idea.

I may be misquoting you here, Anne (please correct me if I am)...  

I remember one of your posts a few months back talking about the need, not
for all web sites to be accessible to the cognitively disabled, but for
there to be more content available, and for that content to be easier to
find.  Tagging the content that *is* appropriate for a particular user
group, combined with some fairly simple assistive technologies, could be
very helpful in finding the content you want.

That's good to know and puts another light on your words....

The problem with putting it in metadata is that it needs to be part of the
basic presentation of the page content. The basic visual presentation and
the basic speech reader presentation.

Yes, this is another side of the "problem" ... the need for an
iconic/graphic version of text is not a cognitive disability need, but a
learning/reading disability need, and probably a need for some who've
suffered brain injuries of various kinds. These are distinct groups of
disabled folks, but there needs sometimes cross over.

If it's not visible, to whom is it useful anyway?

Hopefully, as we develop illustrations for the guidelines themselves, we
will learn something about how a web developer may go about the same task.

I'm sure that will come up. Perhaps that where putting an absolute "reading
level" will be appropriate ... all summaries must be no higher than sixth
grade reading level with xx readability level. We could justify fourth
grade, fifth grade, or sixth grade, if we combine expectation for
cognitively impaired and severely reading impaired users to have speech
equipment to bridge the gap ...

We are saying that all people, even those who are uneducated or uneducable
are accommodated on the web. 

In a sense, Metadata is one way to go. The Title is already in the header
information. Add the Summary, and the Topical Illustration, then the
keywords, and you can display some significant information in a search
engine. But until metadata reaches that realm, and can be set to always
display in a popular browser (IE/NN), let's keep all the componants on the
page or at least on the site if the pages are sequential. 

	But remember I paint in broad strokes. There are many variations
folks with cognitive disabilities as well as those with reading or learning
disabilities with or without cognitive disabilities ...
