Agreed: We need a strategy for how to map the open annotation meta data to
something that ATs will support. Where there are holes we should fill them.
The information is there we just need to adapt it. Also, would this be done
in Readium for readers or should we specify it in the open annotation
effort? ... or a combination?

Robert - Thank you for your feedback.

All -  WAI-ARIA, which is specifically targeted at assistive technologies,
could also be useful here to indicate further indicate the role of an
annotation beyond what oa:motivatedBy does.  I also think using HTML5
microdata or RDFa with the Schema.org accessibility properties, such as
accessibilityFeature with a value of longDescription for an image or MathML
for a formula, could provide a mechanism for users to discover content that
has been annotated for accessibility purposes.  Though there is overlap
between each property their contexts/applications are different: WAI-ARIA
for assistive technologies, OpenAnnotation for annotation systems and
Schema.org for search engine indexing/discovery.  I do wonder though if we
are complicating things to much for tools developers and content creators
by having so many variations depending on the context.

We may want to add to the Annotations specification a section describing
how to best integrate with WAI-ARIA and Schema.org properties.

      Hi George,

      Although the mark up placed in the HTML markup the semantics are all
      name spaced:

      Assistive technologies are not going to understand this.

      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.





      Best

      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

      position paper I recently submitted for the W3C Workshop and they
