limited bitstream permission and Mirador

[Evelin Bányai]

Hello,

There are certain items we would like to have with withdrawn_read bitstream permission so the users should ask for permission to download the full picture. However, if we setup up the item with such permission the built-in Mirador viewer won't show anything.

Is there a way to set up such configuration where the file download is limited but the viewer able to show the image? I have my doubts, but it's worth a try to ask.

We have version 7.2.1.

Thanks!

I have been asked to do this as well. Does anybody know a method?

Which version of Mirador? Mirador 3 supports IIIf Authentication (https://iiif.io/api/auth/1.0/), which seems like the way to do this. Caveat: we have not implemented this ourselves.

Thanks. Apparently we have Mirador 3, we will try to figure out how the authentication works for Mirador.

Best regards,

Hi all,

This is a known issue.  Currently, Mirador in DSpace isn't able to view restricted content, as it cannot pass the authentication info properly back to DSpace: https://github.com/DSpace/dspace-angular/issues/1435

There's been ongoing work on this, but it has hit a number of complications (as it's not simple): https://github.com/DSpace/dspace-angular/pull/1436

I know Michael Spalti (who created that PR) has been interested in this for some time.  There are others who would also like to have this feature... it's just a matter of finding a solution that can work for everyone & that can be added to out-of-the-box DSpace.

So, basically, we don't have a solution yet here. But, I'm hopeful that someone will figure this out & share their approach (whether in code or in a specific configuration) so that we can make it available to everyone. If you'd like to help, you might get in touch via that PR by adding a comment or similar.
