Loretta, et al., proposed a definition of "baseline" for inclusion in the WCAG 2.0 gloassary. Since this is such an important term for us, I thought it might be useful to try to bring together key points in the thread about the proposed definition. This may help us come to agreement. First, here's a definition of the word "baseline" itself, from Princeton University's WordNet 2.0: WordNet 2.0 lists the following as the first sense of the word "baseline": <blockquote> Sense 1 baseline -- (an imaginary line or standard by which things are measured or compared; "the established a baseline for the budget") </blockquote> WordNet then offers the following synonyms for this sense of baseline: <blockquote> => standard, criterion, measure, touchstone -- (a basis for comparison; a reference point against which other things can be evaluated; "they set the measure for all subsequent work") </blockquote> I bring this in just to make sure that we use the word "baseline" in a way that's consistent with this sense of the word. I believe that we *are* using it correctly in what folows (though I'd prefer to replace the word "imaginary" in the definition with something like "arbitrary" instead <grin>. Here is the definition proposed by Loretta, et al: <blockquote cite="http://lists.w3.org/Archives/Public/w3c-wai-gl/2005AprJun/0015.htm l#start"> Definition of baseline: The minimum set of technologies that must be supported by user agents in order to access all information and functionality of a Web site. Developers must ensure that all information and functionality of a Web site conforms to WCAG assuming user agents support only this minimum set of technolgies. Developers may also choose to use technologies that are not in the minimum set provided that the following are true: The Web site is still operable using user agents that only support the technologies that are in the minimum set (i.e. the use of technologies that are not in the minimum set does not "break" the Web site for user agents that don't support them.) All site content and function must be available using only the baseline technologies </blockquote> Jason proposed some changes to the definition, as follows: <blockquote cite="http://lists.w3.org/Archives/Public/w3c-wai-gl/2005AprJun/0040.htm l"> The term "Web site" should be deleted from the definition, and the term "Web content" used instead. Due to our decisions on scoping, what we really mean in this context is "Web content", not "Web site". The term "technology" is not defined. <propose> "Technology" means a data format, programming or markup language, protocol or API. </propose> </blockquote> Then, responding to Roberto Scano's comment that the word "technology" is too ambiguous, Jason added: <blockquote cite="http://lists.w3.org/Archives/Public/w3c-wai-gl/2005AprJun/0077.htm l#start"> This is exactly the worry that prompted me to write a definition. We should choose a better term, agree on a definition, or preferably both. I think "format, programming or markup language, protocol or API" are sufficient to cover everything intended (CSS is presumably a "format" according to this definition). </blockquote> Roberto responded with some additional requirements for what should be included in the definition of "technology": <blockquote cite="http://lists.w3.org/Archives/Public/w3c-wai-gl/2005AprJun/0078.htm l#start"> This is good if we do a definition of technology limited to the www and that involve contents and user agents that must involve: * user agent interface and OS accessibility API support * type of content (markup, programming language, etc.) </blockquote> Tim supplied a; it's not clear to me whether this counts as agreeing with Jason's assertion that CSS is "a format," but it would certainly support the definition of CSS as a technology definition of CSS: <blockquote cite="http://lists.w3.org/Archives/Public/w3c-wai-gl/2005AprJun/0079.htm l#start"> "Cascading Style Sheets (CSS) is a simple mechanism for adding style (e.g. fonts, colors, spacing) to Web documents" - source is [1]: [1]: http://www.w3.org/Style/CSS/ </blockquote> Tim also proposes adding a definition of "content" to the WCAG 2.0 glossary: <blockquote> Also, if "Web content" is being referenced, need to include a definition in [2] (maybe include following points: "something contained in..", "subject matter of written work", or "meaning or significance of work" in our definition (for the Web).. (source for quoted phrases is noun listing of "content" in Webster's II New Riverside University Dictionary 1984) </blockquote> "Good design is accessible design."
