This web site

This web site provides:

  • A search interface to a growing number of indexed Registers:
    • Right now, much of Register 12, and parts of Registers 31 and 5A are available.
    • By the end of 2016, the whole of Registers 31 and 32 will be indexed.
    • We’re also seeking funding to index other Registers. If you would like to talk to us about indexing work, please contact us.
  • Browsing of all 45 Registers, including zoom-able images for each folio
  • .
  • Browsing of people, place and organisation authority files, and subject headings for those Registers that have been indexed.

Indexing the Registers

Approved editors are given access to our editing tool to add rich indexing to the Registers. Currently we have a project ongoing, funded by the Marc Fitch Fund, to index Registers 31 and 32 (1570-1650). Much of Register 12 (Alexander Neville, 1374-1388) was indexed during the original pilot phase of the Mellon-funded Archbishops' Registers project, in 2012. We are seeking further funding to index more Registers. In addition, index data also exists for the Vacancy Register 1304-1306.

The editing tool allows editors to index the people, places, groups, subjects and dates associated with the Registers. Indexing is carried out according to a data model developed for the project:

Access to the data

The project has created some 21,647 high quality images of 45 Archbishops’ Registers. An archival master image is stored in our Digital Archive and is not available for download, but dissemination copies are available. We use an image viewer called ‘openseadragon’ to provide ‘deep zoom’ access online.

The index data itself is available for searching in this web site. Apart from the term lists, subject headings and authority files, the data cannot currently be accessed in a machine-readable form. If you would like access to the underlying data, please get in touch.

Term lists, subject headings and authority files

The project is developing a set of term lists, subject headings and authority files, as detailed below. Subject headings and authority files can be browsed in the site itself.

In addition, there is a REST API for querying accessing these lists. This feature makes use of the questioning_authority gem from the Hydra project . The service will return results structured (JSON) data. Results will, as a minimum, return an id and label. Some terms, for example ‘people’, return additional information.

IIIF Support

IIIF (International Image Interoperability Framework) is an international initiative to provide 'an interoperable technology and community framework for image delivery'. IIIF publish two standards, one for serving images, which allows others applications to make use of images in a standardised way, and another presentation, to enable the standardised description (an IIIF Manifest) of image collections for use in different tools. The project has implemented both standards.

For each register we provide an IIIF Manifest. This is a file containing structured (JSON) data compliant with the IIIF Presentation API (version 2) describing the register and its images.

This manifest can be ‘plugged’ into any IIIF compliant viewer, such as the Mirador Viewer.

The Biblissima Project is a hub for digital humanities projects in France which provides a demonstration version of the Mirador Viewer. It is possible to add your own IIIF Manifest to this demo site.

See a list of available manifests:


The search interface and editing tool have been built using the Ruby on Rails Framework with components from the Hydra Project.

The back-end repository and data store is Fedora Commons (version 4 for the index data, version 3 for the images).

The search index is powered by Solr.

Image viewing is delivered with Openseadragon.

Code for the search interface and editing tool is available on GitHub. The code is not yet fully documented so please contact us if you want to know more.
