On the April 18th call I took an action to address the following bug and just kept going from there: Bug1197: ...Guideline 2.1, "Support formats that enable the creation of Web content that conforms to WCAG": Even after considerable discussion, and following the link to the definition, we were not entirely clear what is meant by "format" here. For instance, we were wondering whether it was related to markup languages, or to doc type schemas, or something else. Please clarify here and then reinforce that in the glossary.... Proposed actions: [Action: 1] Replace “format” with the WCAG 2.0 term "technology" which is defined as: technology A technology is a: - markup or programming language - application Programming Interface (API) - or communication protocol --- [Action 2:] Introduce a new term, "technology-specific WCAG benchmark", to refer to the document that ATAG 2.0 requires evaluators to specify in the conformance profile. (Note: We used to call this a WCAG Techniques document, but techniques documents are non-normative. The nature of the document is actually closer to that of a WCAG conformance claim, except that the “benchmark” document covers a range of potential outputs from an authoring tool rather than some particular Web content as a WCAG conformance claim does. The term would then be defined in its own sub-section of the conformance section. The definition would hit these key points: 1) a benchmark document must specify the version of WCAG used. 2) a benchmark document can specify one or more technologies used together (e.g. plain HTML or HTML + CSS or SVG + PNG images, etc.) 3) the benchmark document becomes *normative* for a particular evaluation by the act of the evaluator including a reference to the benchmark URI in the ATAG 2.0 conformance profile. 4) the benchmark document can be created by any person or organization (although the AUWG does suggest checking to see if a benchmark document has already been published by W3C or another technology developer, before creating a new one). 5) the benchmark document specifies a target WCAG conformance level (single-"A", double-"A", or triple-"A") that the creator of the benchmark is claiming the Web content would conform with if all of the benchmark requirements are met. If the tool allows the author to choose between different WCAG levels, then each level needs its own benchmark document. 6) for each success criteria in *WCAG* that is required by the target WCAG conformance level set in (5), the benchmark document must provide either at least one requirement for meeting the success criteria or an explanation of why that success criteria is not applicable to the technology in question. The AUWG suggests the following documents are relevant when creating a benchmark: WCAG guidelines, "WCAG General techniques" document, "WCAG technology-specific techniques" document (if one exists for the technology in question). [also: Wendy C. say WCAG-GL might create a doc on how to write WCAG Techniques, which would also be relevant here] 7) the benchmark document must be publicly published (the URI will appear in the conformance profile) where it will be open to public and market scrutiny. --- [Action 3:] In checkpoint 2.1, replace "format" with "technology" and use the new term "technology-specific WCAG benchmark", resulting in: 2.1 Support *technologies* that enable the creation of Web content that conforms to *WCAG*. [Priority 1] Rationale: *Technologies* with published *technology-specific WCAG benchmark* documents facilitate the creation of Web content that can be assessed for accessibility with *WCAG*. Success Criteria: - Any authoring tool that chooses the Web content *technology* for the author (i.e. a default document *markup language*) must always choose technologies for which a published *technology-specific WCAG benchmark* exists. - Any authoring tool that allows authors to choose the Web content *technology* must always support at least one technology for which a published *technology-specific WCAG benchmark* exists and always give *prominence* to those formats. --- [Action 4:] In the conformance profile section, make related changes. So that it now reads (including the user agent point proposed in < http://lists.w3.org/Archives/Public/w3c-wai-au/2005AprJun/0007.html >: 1. Required: The date of the conformance claim. 2. Required: The version and URI of the Authoring Tool Accessibility Guidelines 2.0 document that was used for the evaluation. 3. Required: The conformance level satisfied (choose one of: "A", "Double-A", or "Triple-A") 4. Required: The version and URI of the Web Content Accessibility Guidelines document that is the basis for any of the technology-specific WCAG benchmarks used for this evaluation. ( e.g. "Web Content Accessibility Guidelines 2.0 Working Draft, http://www.w3.org/TR/WCAG20/)" 5. Required: The technologies produced by the authoring tool that are covered by the evaluation. For each technology included, the URI of a technology-specific WCAG benchmark document must be provided. (e.g. "HTML4.01, http://www.sample.org/html401_wcag20_benchmark.html)" 6a. Required for Web-based Authoring Tools: The name and version number of the user agent(s) on which the authoring tool was evaluated for conformance. 6b. Required for non-Web-based Authoring Tools: The name and version number of the operating system platform on which the authoring tool was evaluated for conformance. 7. Optional: A description of the authoring tool that identifies the types of authoring tool functions that are present in the tool. Choose one or more of: (a) Code-level authoring functions, (b) WYSIWYG ("What-you-see-is-what-you-get") authoring functions, (c) object oriented authoring functions, and (d) indirect authoring functions. In Limbo: Required: The title/version for the ISO-TS-16071 document that was used as the benchmark for determining the level of Authoring Interface Checkpoints Relative to ISO-TS-16071: e.g. "ISO TS 16071:2003" ----- Cheers, Jan -- Jan Richards, M.Sc.
