Madoc - IIIF transcription, annotation and crowdsource platform

About Madoc

Madoc is an Omeka S based platform for the display, enrichment, and curation of IIIF-based digital objects. The platform is a combination of open source services and technology, bound together to provide a single management interface for IIIF collections. Madoc uses well defined Open web standards like IIIF, W3C Web Annotations and Linked Data.

    As project manager, you can: 
  • Assemble digital collections with IIIF objects from multiple archives, libraries and museums and build an interpretative web site around them.
  • Run a crowdsourcing project and invite the public, researchers or students to contribute.
  • Create a fully customizable 'capture model' to enrich digital objects and image regions with new transcriptions, translations, entities, tags, commentaries and other material.
    • Import and enhance existing metadata and image annotations (such as f.ex. OCR or segmentation) with your own editorial content.
    • Showcase and export the enriched digital collection.
