IIIF (International Image Interoperability Framework) refers to a set of standards for working with digitised historical objects such as manuscripts, single sheets, incunabula and maps. It also refers to the consortium and wider community of practice behind its adoption and development. Collections of image data, metadata and specifications for working with IIIF APIs are organised into so-called IIIF manifests, which are written in JSON-LD (JSON for Linking Data). See https://iiif.io for the website and more documentation there. What this means for CODECS is that its adoption by archival institutions allows us to pull in digitised manuscripts and other objects in IIIF-compliant image viewers and to use tools that lets us engage with the images in many interesting ways.
Note that in rarer cases, the providing institution has not made all of its web services available over an HTTPS connection, even if these days, it is generally the preferred way of serving content on the web. The result is that for security reasons, the content is likely to be blocked, on our server or in your browser, and you may see a blank image viewer, with or without an error message to alert you of the failure. It is to be hoped that all relevant institutions will have been able to complete the transition to HTTPS in the foreseeable future.
