The full-stack IIIF platform
for institutional collections

Glycerine Workbench is a hosted IIIF platform for image
hosting, IIIF manifest generation, collaborative annotation
and publishing.

Curators and researchers bring digitised images together,
annotate and interpret them collaboratively, and publish
them as IIIF, turning isolated images into a shared,
evolving map of knowledge.

One platform, from first upload to published archive

One seamless workflow

From the first image you upload to a fully published, publicly accessible IIIF archive, Glycerine Workbench keeps every step in one place.

Collect

Icon

Create multiple collection sets from images uploaded locally, from IIIF or through your institution.

Collect


  • Bring in images from your own uploads, other institutions or existing IIIF sources.
  • Add images already published online via persistent URLs.
  • Organise images into multiple collections, with multiple image sets inside each
  • Pull material in directly from partner archives and repositories

Annotate

Icon 3

Tag, describe, and link details directly on high-resolution images, in multiple languages and by multiple authors.

Annotate


  • Mark up areas of interest directly on the high-resolution image canvas.
  • Draw detailed annotations with a range of tools including rectangles, freehand shapes, intelligent scissors and AI-assisted segmentation.
  • Combine tags, descriptions, links and locations in a single annotation.
  • Tag with consistent terms and link to related external digital resources and controlled vocabularies.
  • Work across multiple languages.

Build your own templates with flexible fields for different layers across text, image, links and tags.

Design


  • Choose a preset template or build your own custom fields.
  • Build your own custom templates to suit your specific project goals and apply different templates across your collection.
  • Set your own custom details, fields, and taxonomies to image sets.
  • Colour-code annotation outlines to signify different themes, areas and content.

Share a collection and multiple annotation sets, with collaborator control and selective publishing.

Collaborate


  • Share a collection with your research team to build knowledge together.
  • Decide collaborators and annotators, controlling who can create image sets and edit annotation sets.
  • Keep some material private while making other parts public.
  • Run multiple annotation projects concurrently on the same primary collection.

Publish image sets and annotation sets to a public URL, complete with a IIIF manifest.

Publish


  • Publish your high-res images and annotations as standard IIIF manifests that anyone can view.
  • Get a shareable public web address for image and annotation display.
  • Selective publishing, choosing which image sets and annotation sets are ready to go live separately.
  • Keep everything properly linked, structured and compliant for citations.

Create Collections

Bring images together and organise them into virtual collections, grouped by theme, period or project. Glycerine Workbench supports open standards, so your collections stay compatible with your institution’s systems and sustainable into the future.

Annotation Icon Large

Add Annotations

Engrave knowledge across your collection by adding notes, tags and links to images. Invite collaborators to contribute their own annotations, so every image gains more context with every contributor.

Share Icon Large

Display and Share

Published collections integrate into existing platforms, allowing colleagues, students, and the public to explore the work in a range of digital environments. Publish your collection in Glycerine Viewer, a gallery-quality IIIF viewer, or embed it directly in your own site.

Curate virtual collections

Host images online

Upload and publish high-resolution images for research and public access.

Cross-institutional collaboration

Bring together images from multiple institutions in a single virtual collection.

High level thematic structure

Organise annotations using controlled vocabularies, semantic tags and thematic structures. Add critical analysis and interpretation in multiple languages.
