LUNA demo - IIIF Presentation API

[Sheila Rabun]

Hi all,

On the 23 Nov. Community Call, CTO of LUNA, Drake Zabriskie, gave a demo of the latest IIIF functionality in LUNA 7.2.5, which supports the Presentation API. A video of the demo is now available at https://youtu.be/88IkZ0LSWyI.

Hello all,

I have been encountering some problems opening IIIF links from LUNA instances in the Mirador viewer.

This may be an issue for Drake. But it is also worth noting that neither UV or Mirador throws an error to the user to explain why the image is not loading. I'm new to this list, so if I should be posting these issues somewhere else, please let me know.

The IIIF link: 

http://luna.folger.edu/luna/servlet/iiif/m/FOLGERCM1~6~6~1197245~192983/manifest

The Folger links load properly in both Mirador and UV!

Hi Nicole,

both those manifests are working fine for me, for example http://universalviewer.io/examples/?manifest=http://nasaimages.lunaimaging.com/luna/servlet/iiif/m/NVA2~36~36~78865~135659/manifest

I'm not getting the redirect that you are experiencing, from the error messages above. Are you behind a proxy server that's trying to do some authentication before letting you out to the internet? As far as I can see from the error messages, your UV/Mirador requests the manifest, but that request gets redirected to https://weblogin.stanford.edu/login/?RT=... So instead of the manifest JSON, the UV and Mirador are trying to load this page - https://weblogin.stanford.edu/login/. They can't load that page because it doesn't have a CORS header that allows access cross domain. You need to work out why, when your browser requests those first two manifests, it's getting redirected to that login page. What happens when you load the manifest directly?

Thank you, Tom, for your help. We are looking into possible proxy issues on this (Stanford) side. There have been some conflicting reports from my Stanford colleagues about success in opening outside of the Stanford proxy. 

To answer your question, I was not able to open the direct link, either. The error is:

Fetch API cannot load http://nasaimages.lunaimaging.com/luna/servlet/iiif/m/NVA2~36~36~78865~135659/. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://universalviewer.io' is therefore not allowed access. The response had HTTP status code 404. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
