Topic on Talk:Structured Data Across Wikimedia/Image Suggestions

This thread will address two of the topics related to readability and description of images:

1. How can we help users add appropriate captions?
2. How can we help users add appropriate alt-text?

1 - tools to add captions; tool to migrate artwork template machine readable metadata to captions.
2 - tool similar to alt text tool on english wikipedia https://web.archive.org/web/20150211010649/http://dispenser.homenet.org/~dispenser/view/Altviewer https://web.archive.org/web/20160315171621/http://dispenser.homenet.org/~dispenser/cgi-bin/altedit.py Slowking4

Curiosity to Wikidata created a mind-set for images. What do I see? Describe the image. Use few words; discard verbosity. alt text.

Captions are alternate titles of which translate what the picture depicts.

Perceptions of depictions are as varied as the inputs.

For the dyslexic, these two may need inversion.

Maybe this is far-fetched, but Wikipedians constantly captioning images in Wikipedia articles (and other projects). The question is how to incorporate the captions across multiple Wikipedia editions back to Commons and/or Wikidata. Could it be, for example, when I'm editing a File in Commons/Wikidata in my language, and the "smart code" inform me that this File has been used in my language's Wikipedia, and I could click a button to add that caption to the Commons/Wikidata?

The captions of the images used in Wikipedia articles are usually short, descriptive, and has been seen by multiple eyes (more than the description of the file in Commons), so there's a high probability that they are useful additions for caption-less/description-less images. Not true for the reverse: image descriptions in Commons are not necessarily suited to be used as image captions in Wikipedia articles.
