RE: Annotation Accessibility Use Cases...

Hi Rich,
 
I don’t know if such a document exists, however, the body of an open annotation is straight HTML and my understanding that all of the good things that come with HTML5, including ARIA would be included in the body markup.

Hi George, 

Although it would not be in this document I am not seeing a plan for mapping annotations to ones that can be accessed via a reader by assistive technology users or disabled users who do not rely on an assistive technology. We need to see what the mapping would be like from open annotation to content markup to browser export to ATs. Does such a document exist?

example: 

Open annotation -> specific HTML/SVG/MathML/ARIA markup -> platform accessibility API services and/or browser feature.

Hi All, 
  
This looks good. Want to make sure the following is covered: 
  
Not only dss offices etc., but organizations serving persons with disabilities, e.g. the DAISY libraries who have traditionally distributed whole books could possibly move to the distribution of annotations and enhance the fundamentally accessible books. 
  
Also, I would think that providing a link out to repositories of accessible infographics would be a use for annotations; how would this work with ARIA’s describedat? 
  
I expect the metadata would help determine if an external resource is targeted at persons who are blind, low vision,  dyslexic, learning disabled, etc. Also, the term learning disabled is not used internationally.

Re: 
>>> 7. Metadata to identify the descriptions as alternatives or transcriptions of inaccessible or poorly described visual content. 
Metadata about the comment or target resource I think is in the scope of the metadata taskforce, rather than the annotation taskforce? But I'd be interested to hear Bill's thoughts on that? 
  
Yes, I agree this belongs as a metadata use case. Good example of the intersection of metadata and accessibility that I mentioned on last week’s call.

Hi Gerardo, 
  
Thanks for the link and thoughts! :) 
  
Regarding 5 through 8, and inlining them here for ease of discussion, I hope that's okay... 
  
>>> 5.  Support for HTML markup to describe complex images such as pie charts with tables. 
  
The body of the annotation can be of any format in the current OA data model. This is implicit in 2.1.4, but I'll call it out more explicitly.  That said, 2.1.1 does talk about HTML and I could simply remove the "basic" adjective (as what is "basic HTML" anyway?)   
  
>>> 6. Support for MathML to transcribe images that are mathematical formulas (MathML is supported by various Assistive Technologies.) 
As 5.  I can change one of the examples to explicitly call out MathML though? 
  
>>> 7. Metadata to identify the descriptions as alternatives or transcriptions of inaccessible or poorly described visual content. 
Metadata about the comment or target resource I think is in the scope of the metadata taskforce, rather than the annotation taskforce? But I'd be interested to hear Bill's thoughts on that? 
  
The alternatives use cases are: 2.2.6,  2.3.7,  and 2.5.1.  If there's some annotation specific metadata about the transcription/alternative, then I think we should include it in 2.5.1 or a new 2.5.2   
  
>>> 8. A mechanism for original publishers to query, analyze and integrate "crowdsourced" descriptions and transcriptions created by annotation in order to pull those back into the original content. 
  
Yup, I have this exact requirement elsewhere as well -- images of medieval manuscripts are very inaccessible, even to perfectly able scholars :)  I think it's covered, broadly, by 2.4.3.  We could create a new use case that focuses on bringing the data back to the publisher though, rather than the more generic "system" transfer.

Robert - I took a look at the Annotations Use Cases document on the W3C GitHub.  The accessibility use cases <http://w3c.github.io/dpub-annotation/#using-annotation-for-contributing-accessibility-information>  looked good overall.  I checked them against the technical requirements 1-4 in the below position paper I recently submitted for the W3C Workshop and they seem to be covered.  It's less clear to me whether requirements 5-8 in the the position paper are covered, so I would appreciate your thoughts:

Suzanne - I'd be curious as to your thoughts on #8. 
  
Thank You,
