Share a link for opening two or more Canvases, each from a different Manifest
Use case
I want to compare pages from two different manuscripts and share a link to open both of them on the same view. I want to share a link to a colleague showing two similar paintings in two different collections. I want to save my current workspace (open Canvases in the current viewer) for later users. I want to open my current workspace with another viewer.
Mirador already implements a format for exporting the current workspace for sharing or later users. Content State API could be used for the same purpose, adding the advantage of direct loading of the workspace using a crafted link with the iif-content query parameter. The multiple targets for a comparison view section) describes a method for targetting two Canvas at the same time; each Canvas could be from a different Manifest.
Other considerations
We can also assume that viewers that implement the Content State API section regarding the targeting of a Canvas region will be able to open the Canvas and also draw attention to the selected region.
We assume that the two Canvas will be displayed side by side, but could viewers concatenate the two Manifests or open two separate instances of the viewers?
Should we concerned about the length of the final base64URL encoded URL? (it seemed Apache and Internet Explorer were the bottlenecks, with approx. 4000 and 2000 characters, while other technologies usually support up to 40000).
Due to a server delay the issue was duplicated
