ASNT-120: IIIF Presentation API 3 manifest export #155

Overview

Export the open project as a IIIF Presentation API 3 manifest, from the app's File ▸ Export menu and from the web converter. The writer lives in crates/qrate-export so both produce the same file. qrate describes and links to the collection's files; it serves none of them, so it makes no IIIF Image API claim. Branch feature/iiif-presentation, PR #119.

Scope

• In scope: one Manifest per project; a Canvas per row that links a picture, a recording, a video or a PDF; the archival arrangement as Ranges; metadata, navDate and rights from the project's own columns; a report of the rows that could not be carried over.
• Out of scope: hosting files or an Image API service, referencing an existing Image API service, importing manifests, a Collection of per-item Manifests, a new mapping or profile format.

Task Details

1. Writer. qrate_export::iiif_manifest, pure and with no new dependencies, so it also compiles to WebAssembly. Every address is built on the web address the archivist says the export will be published at; files sit below files/ exactly as the ZIP Archive export lays them out.
2. Mapping. From declared column types: Title is the label, Date is navDate when it names one day, month or year, a Rights or License column is rights when it holds a Creative Commons or RightsStatements.org address. Every non-empty cell is a metadata pair.
3. App. A IIIF Manifest… entry that asks for the web address, remembers it in the project, measures the linked files off the UI thread and says what it left out.
4. Web. Project::to_iiif in the WebAssembly interface, and a row on /convert.
5. Docs. docs/export-and-sync.md.

Definition of Done

• The golden manifest passes the official IIIF Presentation validator with no errors
• An exported manifest opens in a IIIF viewer
• A row that cannot be presented is reported, never written as malformed output
• ./scripts/ci.sh passes

Estimate

One session.
