The first implemented feature for Structured Data on Commons will involve file "captions" that enable users to enter a brief description of the media. These captions will allow for multilingual alternative text, and will be stored in Wikibase@Commons via the MediaInfo extension, not Wikidata.
We'll start with exploring designs for the process of adding this captions during the upload process.
Full requirements will be specced out at a later date, but some initial requirements/needs include:
- allowing users to enter captions in more than one language at a time
- Determining an appropriate max character length for captions and how to communicate this clearly to the user
- Considerations for right-to-left languages
- options to use the Filename (minus extension) as the initial text box value for the caption
