Description

Schema definition
longDescription - Descriptions are provided for image-based visual content and/or complex structures such as tables, mathematics, diagrams, and charts

How does this term differ from alternativeText and describedMath?

Mapped ONIX code is much broader as it was for alternativeText and includes video and audio

ONIX codes and definition -
List: 196; Code: 15: Full alternative textual descriptions - All or substantially all non-text content has full alternative (textual) descriptions. Note this applies to normal images (eg photographs, charts and diagrams) and also to any embedded audio, video etc. Audio and video content should include full alternative descriptions (eg audio-described video) and transcript, subtitles or captions (whether closed or open) suitable for hearing-impaired as well as for visually-impaired readers. (Purely decorative non-text content can be ignored, but the accessibility of resources delivered via a network connection rather than as part of the e-publication package must be included)

List: 196; Code:16 - Visualised data also available as non-graphical data
Where data visualisations are provided (eg graphs and charts), the underlying data is also available in non-graphical (usually tabular, textual) form

Action:
Can we make the longDescription term more precise and clearly distinguish its use from alternativeText, describedMath?
