I thought I'd suggest some first "user scenarios". These two linked scenarios focusing on how Wikimedia Commons could function as a "IIIF Server Service" to institutions that have hi-res and openly licensed media, but don't have the resources to set up a IIIF Server of their own.
Wikimedia Commons as a "free IIIF-service"
The majority of GLAMs don’t have the financial resources or technical capability to set up their own IIIF-server. While this may change as vendors of specialised content management and digital asset management systems gradually add support for IIIF this means that IIIF is currently out of reach for most small and medium GLAMs.
Given the above, it could be very attractive a to GLAMs and other institutional users of Wikimedia Commons if all images and videos uploaded to Commons would be “IIIF-ified” and made available via a Commons IIIF Image API and, ideally, IIIF Presentation API.
A service like this would ideally be Wikimedia Commons IIIF-viewer that can be embedded off-Commons (see below).
Possible follow-up features:
- The Category representing the media upload - "Media from GLAM X" - could also be made available as a IIIF Collection.
- While it would be natural to start with images IIIF also supports video and audio. Support for "IIIFifying" video and audio could thus be a feature to add after releases focusing on images. Note that support for video and audio is recent to IIIF and there are not as many (or any?) open source IIIF Viewers that support them.
- When uploading PDFs, or other files with OCRed texts, publishing them also via a Commons IIIF Search APIwould lay the foundations for offering a better online reading experience, many open source IIIF-viewers have display modes optimised for this, including letting users search within the text.
- Allowing the user to annotate media with annotations made available externally in a standards compatible manner, like W3C Web Annotations and that many IIIF Viewers can consume and display. For an image annotation focused proof of concept see Wikidata Image Positions. User annotations could of course also be made possible to apply on texts (highlighting, commenting on or even translating words and paragraphs), video and audio (commenting at certain time-codes and with video also regions). User annotations is a big and complex scenario of its own really!
Support for this case
Based on personal communications with colleagues in GLAMs I think a “Wikimedia Commons as a free IIIF-server” would be a substantial draw. One important reason for this is that a service like this can save money. This is always a powerful argument in cash-strapped organisations and even more so when the COVID-pandemic has left most GLAMs strapped for cash while at the same time having the need to improve their digital services.
Wikimedia Commons as a provider of an embeddable media viewer
For the same reasons that less resourced GLAMs can’t buy or develop IIIF Server support themselves they are also unable to develop/adapt/adopt a IIIF media viewer. For those GLAMs the possibility to use, to embed, a viewer/player/reader from Wikimedia Commons on their own sites is an added benefit.
Another added benefit to the Wikimedia movement is that an embeddable IIIF-viewer will likely also be used in some cases where a user currently would download a media file and then upload it to their own website. This provides the opportunity for more representative view statistics which in turn makes the business case for institutional partnerships stronger. The drawback could be an increased load on the Wikimedia Commons servers.
