Before we begin to create our own manifest let’s take a moment to talk about how parts of IIIF fit together.
A manifest contains different information including links to your images. If you have an image server it’ll include a link to that service for displaying the image.
Here’s how it usually works.
A web page will include a link to a manifest.
Then the client/viewer parses the manifest and finds out which images it will need to request to display the resource.
It will then request the info.json file for each image to know what is available as far as different images sizes and tiles.
Once it has the information the client/viewer can request the actual images and display them.
You’ll notice that the manifest server is separate from the image server. There’s no assumption that the manifest and the images will use the same infrastructure or even be located on the same domain.
In the same way that it is possible to create a static (level 0) Image API implementation, it is also possible to provide manifests as static files or create them dynamically
You’ll also see some examples later of how the manifest server can be provided by a different institution than the institution that hosts the images. Even the source of one image can be different from another. This allows for manifests to be groupings of resources across institutions in creative ways. We’ll see some examples of this later.
