I sent the attached mail a while ago, but it hasn't been successfully sent
to everyone yet.
The file size might be problem, so I will just send PDF and HTML this time.
I hope it works.
Best regards,
Chieko

Page 1. OASIS TC Requirements for ODF Accessibility
- Rich Schwerdtfeger
- IBM Distinguished Engineer, SWG Accessibility Strategy and Architecture
Page 2. Form Accessibility Analysis Sub-team - ODF
- Goal: Produce Accessibility Assessment/Recommendations 3-6 months
- Start in January
- Involve industry support
- Involve advocacy groups and accessibility influencers
- Make ODF more accessible than proprietary document formats
- Provide editor from Oasis
- Select a chair
- Industry technical
- IBM (will involve accessibility experts from Emerging Technologies, Research, and Accessibility Center)
- Sun (Star Office, Accessibility)
- Adobe (Accessibility)
- Corel (Accessibility)
- Advocacy groups and accessibility influencers
- Royal National Institute of the Blind
- Massachusetts commission for the Blind
- Daisy Consortium
- Bay state council for the Blind
- Free Standards Group
Page 3. Accessibility Requirements - Basic Principles
- Ensure Alternative text for all non-text elements
- Ensure text on image maps
- Ensure allowance for relative font sizes
- Ensure provides for structural and list semantics
- Ensure provides for changes in natural language
- Ensure provide for table header and row/column descriptions
- Ensure author can provide a logical keyboard navigation (needed for presentations)
- Ensure may group large blocks
- Ensure label associations
- Link Identification (allow author to describe where a link goes)
- Ensure synchronized media may include captions
- Ensure accessibility features from W3C specifications are supported
Page 4. Accessibility Requirements - Trumping proprietary office formats
- Support DAIST standards for talking books (allow for XSLT conversion to DAISY)
- Enhance Braille support
- Improve the accessibility of presentations
- Z-order
- Groupings
- Navigation
- Relationships
- Slide summary
- Support for tables (include tables in presentations)
- Incorporate Dynamic Web Access Standards being developed in the W3C
- Support for dynamic web content resulting from scripting (would like use cases from ODF Working group)
- Through namespaces or direct incorporation
- Support role attribute from XHTML2
- Document structure meta data
Page 5. API Effort - Exterior to OASIS
- IBM Workplace has built accessibility API extensions for Workplace documents
- Design involved AT vendors and developers up front
- Leverages basic MSAA 1.3 to speed AT vendor support
- Extensions designed to facilitate port to Linux accessibility infrastructure
- Consulted key AT vendors in design (Windows and Linux)
- Extend API to ensure leveraging new ODF accessibility extensions
- Ensure features adopted by FSG for Linux
- Deliver Documentation to industry

- IBM Research, Tokyo Research Laboratory, STSM.
Page 7. Basics of ODF Documents
- XML files and additional resources are zipped in a file
- Core XML files (cited from "OASIS OpenDocument Essentials" http://books.evc-cit.info/)
- contents.xml
- The actual content of the document.
- meta.xml
- Meta-information about the content of the document (such things as author, last revision date, etc.) This is different from the META-INF directory.
- settings.xml
- This file contains information that is specific to the application. Some of this information, such as window size/position and printer settings is common to most documents. A text document would have information such as zoom factor, whether headers and footers are visible, etc. A spreadsheet would contain information about whether column headers are visible, whether cellswith a value of zero should show the zero or be empty, etc.
- styles.xml
- This file contains information about the styles used in the content. The content and style information are in different files on purpose; separating content from presentation provides more flexibility.
- "contents.xml" is the target file, which should be fixed.
- We will discuss only about "contents.xml" in the following presentation.
Page 8. Comparison between MS Office and ODF (in terms of WCAG1.0)
- The significant disadvantages are lack of alternative texts, lack of native tables for Presentation documents and lack of descriptions for links.

Page 18. Example: Tables in Presentation (2)
- 3 subitems...
- For Text documents, ODF v1.0 has elements for tables, such as cells, rows, and headers.
- So, it is suggested to allow table elements in Presentation documents.
- This improvement will allow screen readers to provide table navigation function in Presentation.
