Change Details

== Summary == Rename the table's "Description" column to "**Caption**" — the term Commons / SDC actually uses for the short-label field — and enforce Commons' caption rules (length limit, character restrictions, language tagging). Surface clear error messages on violations and a tooltip that explains what makes a good caption. == Research first == Look up Commons / Wikidata documentation for SDC captions (a.k.a. labels in Wikibase / `mw.cs.label` / `Special:MediaSearch`). Confirm and document in the task: * **Length limit** — believed to be ~250 characters; verify the exact limit and whether it's enforced server-side, client-side, or both. * **Character restrictions** — line breaks, HTML, wikitext, links: which are stripped / disallowed? * **Language tag** — captions are per-language; what's the storage format the API expects? * **Multilingual captions** — note the relationship to T425864's "Add language" placeholder for the Description column. Coordinate with that work if relevant. == Implementation == * Rename the **Description** column header to **Caption** everywhere in the UI (header, columns modal, settings dropdown, etc.). * Add a client-side validator on the cell editor that: ** Blocks / warns on length-limit violations (live character count visible to the user, like a short-form textarea pattern). ** Strips or warns on disallowed characters. * Inline error message immediately below the cell when validation fails; clear actionable wording (e.g. "Captions must be ≤ 250 characters — you have 312."). * Tooltip on the column header (and/or an info icon) summarising "what makes a good caption" — short, plain-language guidance with a link to Commons' caption help page. == Out of scope == * The longer-form file Description (the one stored in the wikitext `description=` field) — captions and descriptions are different fields on Commons; this task is about the SDC caption. * Multilingual caption editing (T425864 placeholder). == Acceptance == * Column header reads "Caption" everywhere. * Typing past the length limit shows a clear error and prevents publish. * Hover / info icon shows the caption-writing guidance. * The validator's behaviour matches what the documented Commons / SDC limits actually are. == Source == User feedback session, 2026-05-10.
