How works TAW?
TAW3 WCAG 1,0 Online
Initially a direction URL is introduced. The system analyzes the page, being based on Pautas de Accesibilidad to the Content Web 1,0, and generates a report HTML based on the page analyzed with information on the result of the analysis.
The report is divided in three parts:
It shows the logo, version of the TAW and version of norms WAI.
The analyzed page is inserting icons of alert on the found problems of accessibility. These icons represent the three levels of priority and can be:
- Priority 1 (red color). The alternative text is “1.automático”.
- Priority 2 (color orange). The alternative text is “2.automático”.
- Priority 3 (green color). The alternative text is “3.automático”
These problems are the automatic denominated ones, those in which the tool has the certainty that they fail to fulfill you rule (for example, an image without alternative text).
Also, also they can appear the following icons that indicate the problems manuals:
- Priority 1 (red color). The alternative text is “1.manual”.
- Priority 2 (color orange). The alternative text is “2.manual”.
- Priority 3 (green color). The alternative text is “3.manual”.
The priority level is the same, but it is problems that need to be reviewed by the developer. One talks about to problems of accessibility under certain conditions that are due to verify (for example, the necessity of a long description for the images ").
Are the found, organized problems of accessibility as a matter of priority, indicating:
- Code of the traffic control point.
- Description of the problem.
- Line number of the analyzed page.
- Label HTML that generates the accessibility problem.
Once finalized the description of found problems summary:
- Time of analysis.
- Total of problems found in the page.
- If an analysis of the page were realized previously and from the same equipment in which it is being realized now, the result of the previous one.
TAW WCAG 2,0 Online
Initially a direction URL is introduced. The system analyzes the page, being based on Pautas de Accesibilidad to the Content Web 2,0, and generates a report HTML based on the page analyzed with information on the result of the analysis.
The resulting page of the form is the document summarize, that shows the total of the problems (the corrections are necessary), the warnings (must be reviewed manually) and the verified points (that they require an analysis complete manual) do not organize and them by each principle (Perceivable, Operable, Comprehensible and Robust).
From this page they summarize is acceded to other three types of views:
Noticeable Vista: similar to report TAW of WCAG 1,0, where they are indicated on the page Web show the detected incidences.
Detail: Where, grouped by each one of the basic principles, the verifications are indicated realized atomics showing the lines of code where incidences are detected. Informative level are the techniques related to each one of the verifications.
Listing: It is a summary, grouped by each one of the basic principles, in format of table that it indicates, concerning norm, the result obtained in the verifications concerning rules.
The application allows to analyze individual pages or complete Web sites. A direction URL is introduced that will be the initial direction to realize the analysis and it forms the scope of the analysis and the traffic control points to verify.
- Scope of the analysis: the consisting of parameters of exploration typology of connections (to follow connections within a directory or a dominion, to follow all the connections or not to follow none), levels to analyze and maximum number of pages are indicated.
- Configuration of you rule: it allows to select what traffic control points will be verified when realizing the analysis of the pages. A predefined set of traffic control points can be chosen according to the accessibility levels or to create a customized set. Also the creation of customized verifications is allowed introducing a regular expression or using an assistant.
In the result of the analysis one is:
- Number of problems found during the analysis for each one of the pages.
- Detail of the problems detected in each page.
The application generates three types of different information:
- Report TAW: it shows in the analyzed page, by means of icons, the place where errors take place. The report is similar to which realizes the version online.
- Report EARL: it creates a report of the page selected in language EARL.
- Final critique: it shows to a final critique that includes all the analyzed pages.
For one more a more complete information on the operation of the tool it consults the manual of TAW3 user.
TAW3 Web Start
TAW3 Java Web Start has the same functionality that tool TAW3 in its unballastable version.
Version TAW3 Java Web Start tries to simplify all the process of installation to the maximum, so that to install an application it is simply to puncture in a connection in a page Web. As of that moment, all the process related to the unloading, installation and execution of the program is realized of an automatic way.
In order to install the tool it is for the first time necessary to use a connection. In order to execute the application later it will be possible to be realized returning to use the connection, from the manager of applications incorporated in Java Web Start or directly by means of direct access.
TAW3 in a click
Once we have installed successfully TAW3 in a click, it will appear his icon in the bar of state of the navigator and we will be able to make an analysis of accessibility of the page Web that we are visualizing then simply clicking in that icon (or using combination CTRL + Mayus. + T).
We will be able to also change the configuration by means of the contextual menu that appears when doing click with the right button on the icon of TAW3 in a click (or by means of the administrator of extensions).
In this menu we will be able to choose the analysis level that we wished, to see information on TAW3 in a click, or to form it by means of the options available, that will allow us to decide where it is going away to execute the analysis (in the present eyelash of the navigator, in a new eyelash that will be abrirá in first plane or background, or a new window of the navigator) as well as the options of menu available.
