Asqatasun v4 - RGAA 3.0 - Rule 6.1.1
Summary
This test consists in checking whether the context of each text link is enough explicit to understand the purpose and the target.
Business description
Criterion
Test
Description
Does each link context meet one of the following conditions (except in particular cases)?
- The link text alone is sufficient to understand the link purpose and target
- The link context is sufficient to understand the link purpose and target
Level
A
Technical description
Scope
Page
Decision level
Semi-Decidable
Algorithm
Selection
Set1
All the <a> tags with a "href" attribute, without children (a[href]:not(:has(*)))
Set2
All the elements of Set1 with a not empty text and without context (assuming the definition of a link context in Rgaa3.0)
Set3
All the elements of Set1 with a not empty text, with a context (assuming the definition of a link context in Rgaa3.0)
in other words :
size(Set1) = size(Set2) + size(Set3)
Process
Test1
For each element of Set2, we check whether the link content is not pertinent (see Notes about relevancy detection)
For each element returning true in Test1, raise a MessageA, raise a MessageB instead
Test2
For each element of Set3, we check whether the link content is not pertinent (see Notes about relevancy detection)
For each element returning true in Test2, raise a MessageC, raise a MessageD instead
MessageA : Unexplicit Link
- code : UnexplicitLink
- status: Failed
- parameter : link text,
"title"attribute, snippet - present in source : yes
MessageB : Check link without context pertinence
- code : CheckLinkWithoutContextPertinence
- status: Need More Info
- parameter : link text,
"title"attribute, snippet - present in source : yes
MessageC : Unexplicit Link With context
- code : UnexplicitLinkWithContext
- status: Need More Info
- parameter : link text,
"title"attribute, snippet - present in source : yes
MessageD : Check link with context pertinence
- code : CheckLinkWithContextPertinence
- status: Need More Info
- parameter : link text,
"title"attribute, snippet - present in source : yes
Analysis
Not Applicable
The page has no textual link (Set1 is empty)
Failed
At least one textual link without context has a text content which is blacklisted or only composed of non-alphanumerical characters (Test1 returns false for at least one element)
Pre-qualified
In all other cases
Notes
We assume here that the links are only composed of a text. (<a href="https://asqatasun.org/target.html">my link</a>)
All the links that have children different from <img>, <canvas>, <object> or <svg> are considered as combined links.
Definition of not-pertinent link title :
A link title is seen as not-pertinent in the following cases :
- the link title is blacklisted (regarding the LinkTextBlacklist nomenclature)
- the link only contains not alphanumerics characters
