OK, I've gone through several of the audio/video examples, which had one of the following possible issues: * Wasn't a realistic illustration, eg wasn't a true representation of a captioning scenario, or of full-description audio. I've replaced each of these with an example that uses the "spacetime" video. * Some kind of bug, like the messagebox example several of you saw. * Poor modal behavior, where you couldn't toggle between modes or exit modes. The techniques affected are as follows: SL1, SL3, SL12, SL16, SL17, SL24. Also, SL15's working example had a production issue, combined with an unexpected hotkey-hijack by some browsers like FireFox 4, so I needed to rebuild it. The source will have to be republished to w3c server this time including the "source" directory from the ZIP. Following is a more complete listing of what I did to working examples that affects the silverlight-tech-src.xml file, the various working-example sources, or both. This detailed listing is probably of concern mainly to Michael. EXAMPLES-RELATED CHANGE LOG: SL1 - Addressing comments re: realism of the working example. Adapted the sample to include a modal button, and reference the "spacetime" video along with a blended default+interstitial full-description track. updated Example code directly in xml MUST UPDATE working-examples/SL1/AlternativeAudioChannel.xap ; it is TOO LARGE to upload to WIKI, will attach in mail SL3 - fixed MessageBox, made the controls modal updated Example code directly in xml MUST UPDATE working-examples/SL3/MediaElementControls.xap, using new XAP from http://trace.wisc.edu/wcag_wiki/index.php?title=Image:MediaElementControls.zip SL12 - made the controls modal updated Example code directly in xml This also points to working-examples/SL3/MediaElementControls.xap SL15 -changed example to use different hotkey combo, and use mouse buttons rather than mouse movement updated Example code directly in xml MUST GET new copy of http://trace.wisc.edu/wcag_wiki/images/7/73/Popup_keys..png and possibly update height/width MUST UPDATE all working-example files from http://trace.wisc.edu/wcag_wiki/index.php?title=Image:ApplicationLevelKeyHandling.zip IMPORTANT: make sure to include the /Sources subfolder on the HTML server (it contains resources that are needed for the example to visualize) SL16 - Addressing David MacDonald's comment that the original example was not a good captioning example, so I changed the media source updated Example code directly in xml MUST UPDATE mediatimelinemarkers.xap file ; it is TOO LARGE to upload to WIKI, will send to Michael only in mail SL17 - Again addressing comment by David MacDonald that the non-realism of the example makes it hard to tell what is really being illustrated. Edited example to have real audio and real transcript, plus modal controls. updated Example code directly in xml, and also edited the text intro to Example 1 deleted previous Example 2 entirely MUST UPDATE replaceaudiowiuthtranscript.xap file, using new ZIP from http://trace.wisc.edu/wcag_wiki/index.php?title=Image:ReplaceAudioWithTranscriptText.zip SL24 - created a new sample, had previously tried to repurpose a working example that wasn't appropriate updated Example code directly in xml, and changed reference of "working example" <loc> to point to a differently named TestPage.html MUST UPLOAD NEW working-examples/SL24/MedialElementControlsAutoPlay.xap and working-examples/SL24/MedialElementControlsAutoPlayTestPage.html from http://trace.wisc.edu/wcag_wiki/index.php?title=Image:MediaElementControlsAutoPlay.zip From: David MacDonald [mailto:david100@sympatico.ca] Sent: Thursday, March 24, 2011 11:50 AM To: Wolf Schmidt; 'Loretta Guarino Reid'; 'List WAI GL' Subject: RE: Review notes for Silverlight techniques I'm doing SL#17 The working example doesn't seem to behave as expected. Maybe I'm missing something, but as soon as the "Display Transcript button" is activated, the controls disappear and text across the top says "The following text..." but there does not appear to be any text transcript... and the only way to bring back the controls is to reload the page. http://www.w3.org/WAI/GL/WCAG20-TECHS/working-examples/SL17/ReplaceAudioWithTranscriptTextTestPage.html Maybe someone else wants to look at it... Cheers David MacDonald www.eramp.com<http://www.eramp.com> PS that's the end of my 3 but I think I will go through and check some more test files. That seems to be the tough part... I'm all for "downloadable code samples" for any working model examples.

I already reported that issue to Michael. You know, what might be happening is that my choice of the Ctrl+ (plus) key is actually intersecting a browser-reserved key combo that I hadn't seen on IE 8, that makes the whole browser zoom as a non Silverlight behavior. I will test this tomorrow with the browsers you mention. (I hadn't been testing with IE9 because the prerelease versions broke my Windows-Eyes install.) ________________________________ From: w3c-wai-gl-request@w3.org [w3c-wai-gl-request@w3.org] on behalf of David MacDonald [david100@sympatico.ca] Sent: Tuesday, March 22, 2011 7:35 PM To: 'Loretta Guarino Reid'; 'List WAI GL' Subject: RE: Review notes for Silverlight techniques I just did a review of SL15. * SL15: http://trace.wisc.edu/wcag_wiki/index.php?title=Providing_Keyboard_Shortcuts_that_Work_Across_the_Entire_Silverlight_Application The text seems fine, given that the target audience are SilverLight programmers... no typos etc... I cannot evaluate SilverLight code.

This is an enormous editing task. I'd like WG members to sign up to review different techniques, so we get complete coverage. We should review all the Silverlight technique in the next 2 weeks, so we'll be ready for more reviews when the PDF techniques are ported. Please pick 3 techniques to review. I have set up a sign-up page at http://www.w3.org/WAI/GL/wiki/Reviews; please put your name on the items you are reviewing, so we don't duplicate effort. If you will not be able to review techniques in the next few weeks, please let me know.

I anticipate various issues with them due to errors on my part, and minor differences between the structure in the wiki and the structure we've been using for the other technologies. I enhanced our structure a bit to meet what I saw in the wiki but could have introduced various subtle errors, even into techniques we haven't touched. Here are some questions it would be helpful for you to think of as you review these. I expect different people will look at different levels of detail, but I'm hoping we can get review of all these issues from at least somebody. For reference, the set of techniques by number and the wiki page I ported them from is included at the bottom of this message. * Are there typographical or formatting errors? * Is there missing content? * Are heading levels correct, in the single-page, by-technology, and complete views? * Are the references to success criteria correct? * Are references to related techniques correct? * Are there broken links? * Are there broken images? * Is the alt text of images appropriate? * Do any images require extended descriptions? If so, what should the description be? * Most of the techniques in the wiki had test files / sample files at the bottom. In our other technologies, we've been putting links to such files at the bottom of an example, not at the bottom of the technique as a whole. Is the location of the references to such files appropriate for each technique? * References to test / example files are usually in the form of "...working example of XYZ". Is the verbiage I pulled out of the air for "XYZ" in these links ok? Note it needs to be fairly distinct, not something like "this example", because of the need to have unambiguous link text in views that have all the techniques together. * Do all the test / example files work? I modified some of them slightly to fit into a standard approach. * Is there / should there be downloadable source code for the test / example files? This is what we did for Flash. * Are code samples appropriately formatted? I took them unchanged from the wiki and didn't run any "pretty print" process on them. What would be most useful here is a complete reformatted version, rather than instructions on what needs doing, which is VERY painstaking to implement. * Are test procedures self-consistent and correct? I tweaked them a bit for consistency with our other techniques. * Some techniques (SL5, SL13, SL18, SL30, SL33) have more than one test procedure. Does the implementation of this work? There are a few things I haven't yet done, in case you notice going through: * Techniques have pointers to the success criteria / Understanding document, but I haven't added pointers in the Understanding to the new techniques yet. This will need separate review when it's done. * There is diff markup that hasn't been cleared out yet, because I'm a bit nervous of the tool that does this... This won't be seen in the Silverlight techniques, though, because they're all new. * Language-specific terms just have generic emphasis, rather than more appropriate markup / formatting. * Advisory techniques are indicated as such in the XML but this doesn't yet show up in the HTML.
