OpenAtlas

I'm quite positive, that this is a backend issue, because the IIIF manifest uses the the frontend link provided by the OpenAtlas backend, if any is given.

In this case, I fear you have to construct your own URL with the ID.

Thanks for the feedback Bernhard. I was talking with Christoph about it yesterday too.
Although the link is provided by the backend API there is not much we can do about it there because the backend isn't "aware" which presentation site is asking.
So it may be easier to change/adapt the URL on the frontend side because the alternative would be the presentation site communicating the correct URL so that the backend can include which sounds kind of backward.

That's why we leave the issue at the frontend for now, but this can be of course discussed further in case it turns out to be too troublesome implementing at the frontend.

We may should discuss the backend API using the registered frontend URL for that in general. It's main use was to provide frontend links in the backend but because it will happen more often that multiple frontends use the same backend we may should limit it to that. Or leave it like is to have at least a default for frontend requests. However, let us take care of the bug first and maybe discuss the rest in Autumn in more detail.
