Wendy, responding to one of my posts yesterday:: <blockquote> >Editorial Note:The use of "clearly" and "concisely" makes this >untestable. >Will that be an issue for readers? >[js: I hope not-- the idea here is to provide guidance that helps people >understand what they need to do. We could add a note saying that clarity >and concision require human judgment, and that such judgment should be >informed by at least informal feedback from users, or at best by formal >user testing.] WAC: My intent with this note was to get feedback from people about what they expected to see at the gateway level. Thus, I'm tempted to leave the note as it is and see if we get any responses. Thoughts? </blockquote> John: I agree that feedback from the list is important! But I do want to make a case for allowing the Gateway document to discuss techniques and strategies that may not be testable, or, in cases where techniques may produce results that aren't *machine*-testable, to include suggestions about testing techniques as well. Wendy again: <blockquote> >Editorial Note: In this draft, part C of the Level 1 success criterion >for >Guideline 1.1 is divided into two techniques this one (music without words) >and the next (visual art). Is this confusing? Should they merge into one? >[js: I think it would be more confusing to treat the tasks of describing >non-vocal audio and visual art somewhat differently-- the descriptive >techniques and vocabularies are very different, and so is the issue of >what gets "displayed," since you can't "display" audio. We may need to add >a note to this effect.] I interpret this as, "keep the two techniques separate because the strategies and vocabularies are different." Is that what you intended or were you aiming for something else? </blockquote> John: Yes, I intended to say keep these items separate because the strategies and techniques are different." In another message to the list yesterday [1], I added some other thoughts about this issue, which I'll paste in below for convenience' sake: <blockquote> There are significantly different requirements for different types of audio content, and I think they're covered by different items under 1.1 L1 SC 1. In my judgment, spoken-word audio would be covered by ther requirement to provide "the same information" as the non-text content-- in this case, a text transcript that includes the words in the recording. For non-vocal music, the minimum requirement is for a text label that identifies the piece. Typically this would be provided via alt text on a graphical link to the audio file (such as an icon of an ear or something) or by a a text link. In some contexts (e.g., a history of music or a music review) it might be appropriate to include an additional text description of the piece. This could be done in several ways, including nested <object> elements, etc. In any case, I think we can solve the problem by dealing with spoken-word audio under the requirement to provide the same information and with non-vocal music under the requirement to identify non-text content that creates a specific sensory experience. </blockquote> [1]http://lists.w3.org/Archives/Public/w3c-wai-gl/2004JulSep/0248.html#s tart Hope this helps!
