Technical description

Scope : page

Decision level : semidecidable

Algorithm

Selection

Set1 (object tags with a type attribute that starts with "image" identified as an informative embedded image from html markers)

All the object tags not within an a tag (in this case, the object image would be considered as a link) with an type attribute that starts with "image" and with an id attribute or a class attribute or a role that matches one of the values set by the user through the "INFORMATIVE_IMAGE_MARKER" parameter.

Set2 (object tags with a type attribute that starts with "image" not identified as an informative object image from html markers)

All the object tags not within an a tag and with a type attribute that starts with "image" that don't have an id attribute or a class attribute or a role that matches one the values set by the use through the "DECORATIVE_IMAGE_MARKER" parameter or the "INFORMATIVE_IMAGE_MARKER" parameter. That means select all the object tags not within an a tag with an type attribute that starts with "image" of the page when these parameters are empty.

Process

Test1

For each element of Set1, raise a MessageA.

Test2

For each element of Set2, raise a MessageB.

MessageA : Check detailed description pertinence of the informative object image
  • code : CheckDescriptionPertinenceOfInformativeImage
  • status: Pre-qualified
  • parameter : text, data attribute, Snippet
  • present in source : yes
MessageB : Check the nature of the object image and the pertinence of its detailed description
  • code : CheckNatureOfImageAndDescriptionPertinence
  • status: Pre-qualified
  • parameter : text, data attribute, Snippet
  • present in source : yes

Analysis

Not Applicable

Set1 and Set2 are empty (the page has no object tag not within an a tag and with a type attribute that starts with "image")

Pre-Qualified

In all other cases
