End to End analysis of Guideline 1.1, Phase 1 and 2

About this document:

This document outlines the results for the end to end exercise for Phase 1 and 2 for Guideline 1.1

Phase 1 maps the Success Criteria to the corresponding Technology Independent, HTML and/or CSS techniques.

Phase 2 maps the Examples to the corresponding Technology Independent, HTML and/or CSS techniques.

Issues

In HTML Techs, "10.2 Image titles" does not correspond to any success criteria. It provides additional information, not a text equivalent.
Examples refer to short equivalent, short label, longer description. We need to specifically spell out which element/attribute/etc that this applies to for each technology.
We need to make sure that the examples have complete test suites. If we don't have a test suite, then the example needs to be changed, removed, etc.
Need boundary for short and long, otherwise how do you know when to switch from one to the other.
Short equivalent, short label -- are these the same thing? If they are, lets use one term. If they are different, please explain how they are different.

	Guideline	Technology Independent Doc	HTML Techniques	CSS
Guideline 1.1	For non-text content, provide text equivalents that serve the same purpose or convey the same information as the non-text content, except when the sole purpose of the non-text content is to create a specific sensory experience (for example, music and visual art) in which case a text label or description is sufficient.	n/a	n/a	n/a
Level 1 SC #1	Level 1 Success Criteria for Guideline 1.1 Text-equivalents are explicitly associated with non-text content, except when the non-text content is intended to create a specific sensory experience (for example, music without words and visual art). [I] The text equivalent fulfills the same function as the author intended for the non-text content (that is, it conveys all of the intended information and achieves the same function as the non-text content). Exception: If the purpose is to let users provide the text-equivalent (for example, a spelling test) then the text-equivalent is not required.	1.1.1 Text Equivalents	10.1 Short text equivalents for img elements ("alt-text")HTML-TECHS: 10.3 Short text equivalents for object elements ("alt-text") HTML-TECHS: 10.4 Long descriptions of images	CSS?
Level 1 SC #2	Non-text content that is designed to create a specific sensory experience (such as music without words or visual art) has a text label or a text description explicitly associated with it. [I]	TID?	HTML?	CSS?
Level 2 SC	No level 2 SC for this guideline	n/a	n/a	n/a
Level 3 SC #1	A text document (for example, a movie script) is provided that includes all important visual information, dialogue, and other important sounds. [I]	TID?	10.1 Short text equivalents for img elements ("alt-text")HTML-TECHS: 10.3 Short text equivalents for object elements ("alt-text") HTML-TECHS: 10.4 Long descriptions of images	CSS?
Example 1	An image used as a button. (short equivalent for function) A right arrow icon is used to link to the next slide in a slide show. The text equivalent is "Next Slide," so that a screen reader would read the phrase "Next Slide" and automatically identify it as a link by adding the word link or changing the synthesizer's voice.	Need short equivalent defined.	Need short equivalent defined for HTML. IS it alt, title or both?	n/a
Example 2	A data chart. (short label + longer description) A bar chart compares how many widgets were sold in June, July, and August. The short label says, "Figure one - Sales in June, July and August." The longer description identifies the type of chart or graph, provides a high-level summary of the data comparable to that available from the chart or graph, and provides the data in a table or other accessible format.	Need short label and longer description defined?	Need short label and longer description defined for HTML. Alt, title, longdesc?	n/a
Example 3	An animation. (short label + longer description) An animation shows how to tie a knot. The short label says, "An animation showing how to tie a square knot." The longer explanation describes the hand movements needed to tie the knot.	Need short label and longer description defined?	Need short label and longer description defined for HTML. Alt, title, longdesc?	n/a
Example 4	An audio file of a speech. (short label + transcript) An audio file is embedded in a Web page. The short label says, "Chairman's speech to the assembly." A link to a text transcript is provided immediately after the audio clip.	Need short label defined.	Need short label defined. How should the transcript be marked up?	n/a
Example 5	An audio file of a symphony. (short label) An audio file is embedded in a Web page. The short label says, "Beethoven's 5th Symphony performed by the Vienna Philharmonic Orchestra."	Need short label defined.	Need short label defined for HTML. Alt?	n/a
