Viewer Mirador

Viewer Mirador is a lightweight online tool designed for researchers, librarians, curators, and developers to preview IIIF manifests with a Mirador-like viewing experience. It accepts a manifest URL and renders the manifest's structure, including sequences, canvases, and basic annotation references, without requiring deployment of a full client. The tool focuses on the organization of content rather than asset delivery, enabling quick checks during acquisition, collection curation, metadata validation, and scholarly review. By loading a single manifest, users can evaluate ordering, presence of canvases, and annotation availability before integrating assets into local deployments.
It operates conceptually by fetching the manifest, validating its JSON structure against the IIIF Presentation API, and extracting a navigable list of canvases and their labels. The core data model includes: manifest, sequence array, canvas array, and optional annotation lists. The tool computes a simple, stable view of the current canvas and provides a compact summary of metadata and relationships. Outputs include a current_canvas_id, a canvases array with ids and labels, and an annotations_present flag, along with a metadata object.
Use cases span library QA workflows, curatorial reviews, digitization projects, and research studies where researchers need rapid manifest assessment without full viewer setup. The tool's unique value lies in its minimal dependencies, fast loading, and explicit focus on structure rather than media delivery. Core features include manifest loading, canvas enumeration, annotation presence indicators, and a lightweight export of the manifest state for collaboration or audits.
