Add "Glycerine" to the "Data Annotation" section.

Short pitch

Glycerine provides a suite of annotation tools and end-to-end workflows for researchers, curators and students to collaborate on projects across repositories. Images can be organized into collections and shared with collaborators. Sets of annotations can combine semantic tags from domain-specific vocabularies with critical analysis in multiple languages. Annotated images can be published as research outputs in immersive and engaging visualizations and archived in sustainable formats.
