is the text property the equivalent of an alt-text when required?

[llemeurfr]

In this sample comics page sample

{
  "role": ["page"],
  "imgref": "page10.jpg",
  "children": [
    {
      "role": ["panel"],
      "imgref": "page10.jpg#xywh=percent:10,10,60,40",
      "text": "panel 1 text"
    },
    {
      "role": ["panel"],
      "imgref": "page10.jpg#xywh=percent:70,50,30,50",
      "text": "panel 2 text"
    }
  ]
}

Is the 'text' considered a proper alternative text describing the image?
This is not so obvious because the definition of the "text" property ("Textual equivalent ...") is not explicitly usable as a description.

No, text is not meant to be a description, it's mostly meant for providing a textual transcript which is not the same. Look at appendix C for an early example of what I'm proposing for description.

Here's also a full example from my response to Arcom:

{
  "role": ["page"],
  "imgref": "page10.jpg",
  "children": [
    {
      "role": ["panel"],
      "imgref": "page10.jpg#xywh=percent:10,10,60,40",
      "description": "Emily marche seule, elle semble perdue dans ses pensées. Derrière elle, deux policiers la suivent du regard et échangent à son propos.",
      "character": ["Emily", "Premier policier", "Deuxième policier"],
      "children": [
        {
          "imgref": "page10.jpg#xywh=percent:10,10,30,20",
          "character": ["Emily"],
          "children": [
            {
              "role": ["thoughtBubble"],
              "text": "Quel étrange sentiment."
            },
            {
              "role": ["thoughtBubble"],
              "text": "J'accède enfin à ce poste tant convoité, et pourtant…"
            }
          ]
        },
        {
          "imgref": "page10.jpg#xywh=percent:40,10,20,20",
          "character": ["Premier policier", "Deuxième policier"],
          "children": [
            {
              "role": ["speechBubble"],
              "text": "Hé, c'est pas elle, la fille qui a arrêté le type de l'autre soir, celui qu'on a envoyé à Wormwood ?",
              "character": ["Premier policier"]
            },
            {
              "role": ["speechBubble"],
              "text": "Ouais ! Il paraît qu'Hawkins y serait passé si elle n'avait pas été là.",
              "character": ["Deuxième policier"]
            }
          ]
        }
      ]
    }
  ]
}

Therefore it is time to add the description property to the model :-)
And the character property would be useful to add for discussion also.

[HadrienGardeur]

I agree and that's why description is already listed under TODO and character will end up there as well once I have a rough idea whether we should go beyond just character names.

I've identified the following information as useful for characters:

• identifier
• gender
• age
• a phonetic transcription of a character's name

The identifier is useful to uniquely identify a character (for example to build an index), whereas gender/age/phonetic transcriptions are all useful for a read aloud feature.

Also, if a node contains both a text and a description, it would be useful to have a "how to" explaining that the two pieces of information should be both provided to the user, using different affordances.
