Integrating IIIF annotations in DSpace

Since 2017, 4Science has been working on implementing support for IIIF in DSpace to provide a better user experience in enjoying images, especially in the cultural heritage domain. To achieve this goal, a dedicated add-on has been implemented, easily integrated with a set of external Image Servers, such as Cantaloupe or Digilib. To enrich the content related to the digital cultural heritage managed within DSpace, we are now implementing workflows aimed at saving IIIF annotations created with Mirador and at relating them with all the information provided by metadata, fulltexts and entities. The proposed paper illustrates such workflows and how to relate annotations to each other and to other entities structured at data model level, in order to integrate them in the repository knowledge base.
