Business description
Criterion
Test
Description
- L’intitulé de lien seul permet d’en comprendre la fonction et la destination ;
- Le contexte du lien permet d’en comprendre la fonction et la destination.
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
