1-1. This Site and IIIF

• The University of Tsukuba Digital Collections (hereafter “this site”) supports IIIF (International Image Interoperability Framework). Each item’s detail page provides a link to the IIIF Manifest, which can be used in any IIIF-compatible viewer.

1-2. IIIF Overview and Interoperability

• IIIF is an international framework for the interoperable delivery and exchange of images and metadata on the internet. It enables the following forms of interoperability.
• IIIF comprises multiple APIs (e.g., IIIF Image API, IIIF Presentation API) that standardize high-resolution image delivery, sharing of structured metadata, and functions such as search and authentication.
• Items on this site may be used from any IIIF-compatible viewer.
  For example: Mirador, Universal Viewer, etc.
• IIIF-compatible viewers allow cross-institutional and cross-platform viewing and comparison.

1-3. Key Features Enabled by IIIF

• Comparison display of multiple items
  Multiple IIIF items—such as different editions of the same work or items held by other institutions—may be placed on the same screen. For details, see 5-4. Multi-Window Feature.
• Cropping and transformation of images
  Using the IIIF Image API, images can be retrieved by specifying region, size, rotation, format, and related parameters. For example, the IIIF Curation Viewer (CODH) (in Japanese) enables extraction of highlights from multiple items for side-by-side viewing.
• Sharing annotations
  External services allow annotations to be added to items.
  
  Please make use of these functions in contexts such as research, education, and learning.

1. Obtain the IIIF Manifest URL from the relevant item's details page on this site.
