This action is related to the long call in Jan 20, 2012. 1.11.2 was on the list for a yes/no vote. it had a note of "email thread". here are the threads related to this SC. Now we need to decide is it ok Simon original proposal http://lists.w3.org/Archives/Public/w3c-wai-ua/2011JanMar/0040.html Greg response http://lists.w3.org/Archives/Public/w3c-wai-ua/2011JanMar/0046.html discussion in meeting http://lists.w3.org/Archives/Public/w3c-wai-ua/2011JanMar/0050.html Writing: review and approve 1.11.2 - Extended Link <jeanne2> [34]http://lists.w3.org/Archives/Public/w3c-wai-ua/2011JanMar/0040.h tml [34] http://lists.w3.org/Archives/Public/w3c-wai-ua/2011JanMar/0040.html Greg in email asked if it was about making info available directly to the user, or to assistive technology. Simon says he assumed it was about presenting it directly to the user. What would example implementation be like? Simon: in Wiki system a small icon identifies links to offsite resources. Simon sees a browser having a preference setting to "turn on extended link information" which displays all of these pieces of information next to the link. Simon: browser can tell by MIME type whether it would download, run automatically, prompt for handling, spawn external renderer, etc. Wouldn't the browser need to query the server to get MIME type? In some cases the browser can guess by file extension, but I don't think we want it to query the server for each link. In email suggested changing the SC wording to incorporate "recognized". Greg: what did you mean by hover? Simon: In CSS you can change link color based on hover. Jeanne: Need to be aware of giving users so much information that we impede their ability to navigate the page. To make it clearly about presenting to the user, could change "The following information is provided for each link (Level A)" to "The user can have the following information about a link presented (Level A)" or some such. Jan: Information presented on hover needs to also be available to AT and to keyboard users. <Jan> Jan: Also wonders whether all this link info is accessibility or usability In response to Jan's question, I think visited/unvisited is accessibility because it greatly reduces short-term memory load. I have trouble imagining any browser not showing link element content. Jan suggests information related MIME type, size, etc. can be done at link activation time, rather than displaying it on the page. Simon notes it's much more efficient for some users if the information is presented with the link rather than elsewhere (e.g. in a status bar). Similar question about whether it's OK to make the info available on request (e.g. on a link's shortcut menu) vs. showing the information for all links on the page IN the page. Jan notes that information appearing somewhere other than where you're working is a general accessibility problem. Simon adds tab order and access key as important pieces of information. Do people feel the things Simon proposed as Level A are all accessibility, not just usability? Element contents, title, visited/unvisited, hover text (or hover content), and whether it's currently selected? The ability to customize highlight used for selected, visited and unvisited links are all covered by SC 1.3.1 Highlighted Items and 1.3.3 Highlighted Input Controls. So we may not need to repeat that here, but could list it in the Related Resources. Jan is OK with merely cross-referencing those here. <Jan> Jan: hmmm that wasn't me So if visited and selected are covered elsewhere, that leaves link content, link title, and hover content as still needing to be somewhere. Title could be considered alternative content, which is also addressed by another SC? <Jan> JR: Idea: Proximity of Status Information: The user can specify that status information for elements always be displayed in proximity to the element. (e.g. rather than in status bar etc.) Jan doesn't think the HTML title attribute would fall into the category of "alternative content" because it's not meant to REPLACE the primary content. Does that mean we need some SC to require access to title attributes? Or is that implied by the fact that if they show it to a mouse user they have to show it to keyboard users as well? If a browser chooses to not expose title attribute to anyone, mouse or keyboard users, is that acceptable? Simon says if it's OK if it's not available to anyone. One argument that could be made for presenting title being an accessibility issue is that if a person can't see a graphical link, the title might give them more information to help them understand it's purpose, above and beyond the alt attribute. So should we remove link title from 1.11.1? Discussion of the difference between things that we feel the browser needs to do to be accessible (e.g. ability to turn off images, providing keyboard shortcuts) , and things it needs to do for some users if it does equivalent for others (e.g. keyboard access to all features you ca do with mouse). <KimPatch> stepping away for a minute If we say that browsers don't have to display title attributes, but if they do they have to make it available via the keyboard, that's handled by another guideline so we wouldn't need to mention it here, right? <KimPatch> back Jan suggests creating something about the user option to have information displayed in proximity to the thing it is associated with, rather than elsewhere as in a status bar. We do something similar in 2.1.6 (former 4.1.6) Present Direct Commands in Rendered Content: The user can have any recognized direct commands (e.g. accesskey) in rendered content be presented with their associated... scribe: elements (e.g. "[Ctrl+t]" displayed after a link whose accesskey value is "t", or an audio browser reading the value or label of a form control followed by "accesskey control plus t"). (Level A) The intent for that is Intent of Success Criterion 2.1.6 (former 4.1.6): Make it easy to for users to discover or be reminded of keyboard shortcuts and similar commands without leaving the context in which they're working. Easy keyboard access is especially important for people who cannot easily use a mouse. <Jan> ACTION: Jan to Work on SC wording related to "Proximity of Status Information: The user can specify that status information for elements always be displayed in proximity to the element. (e.g. rather than in status bar etc.)" perhaps making use of wording similar to Intent of Success Criterion 2.1.6 (former 4.1.6): [recorded in [35]http://www.w3.org/2011/02/03-ua-minutes.html#action11] -- Jim Allan, Accessibility Coordinator & Webmaster Texas School for the Blind and Visually Impaired 1100 W. 45th St., Austin, Texas 78756 voice 512.206.9315 fax: 512.206.9264 http://www.tsbvi.edu/ "We shape our tools and thereafter our tools shape us."
