Cantaloupe and Mirador setup help, Please

[Chris Clawson]

I have been struggling for days to get IIIF support running in my DSpace 7, with Mirador and Cantaloupe. This following link shows how far I got:

https://meloware.org:8443/handle/123456789/19

There are several images in this item and the Mirador viewer seems able to recover the image metadata, but is encountering a network error when trying to retrieve the actual images. This item has the metadata field dspace.iiif.enabled added and set to 'true'. The error message is “TypeError: NetworkError when attempting to fetch resource. “

I could use some help at this point as to why these images aren't being displayed.

This is a server container running Ubuntu 20.04. Apache2 has an open port (443) which is a Virtual Host to Wordpress. This is controlled by the /etc/apache2/sites-available “wordpress.conf”. The Virtual Host file “dspace.conf” uses port 8443 to reach Dspace 7 and 8183 to talk to Cantaloupe. My problem may be here, but I am tired of guessing.

Other important config files are also included. I can always provide more info, if asked.

Sorry to see you still facing an issue with the image server. Just follow the steps to get it working. I had to separate the virtual hosting config files because (a) Frontend reverse-proxy settings conflicts with the image server setting (b) To save you some bucks buying a newer certificate.

You need to drop the attached apache config virtual hosts config files into /etc/apache2/sites-available/

# You also need to add a newer port (444) as you see it below.
vi /etc/apache2/ports.conf
<IfModule ssl_module>
        Listen 443 https
        Listen 444 https
        Listen 8443 https

# Enable the new virtual site

a2ensite img.conf

# Open port 444 in the firewall if you have the default ufw firewall enabled and running.

ufw allow 444

# Restart the Apache webserver
systemctl restart apache2

# In cantaloupe.properties configuration file you need to set the following configuration options as you see them:

http.enabled = true
http.host = localhost
http.port = 8182
endpoint.admin.enabled = true
endpoint.admin.username = SET-THE-ADMIN-USERNAME-HERE
endpoint.admin.secret = SET-A-SECURE-PASSWORD-HERE
source.static = HttpSource
HttpSource.BasicLookupStrategy.url_prefix = https://meloware.org:8443/server/api/core/bitstreams/
HttpSource.BasicLookupStrategy.url_suffix = /content

# In /opt/dspace/config/modules/iiif.cfg :

iiif.enabled = true
iiif.image.server = https://meloware.org:444/iiif/2/

Let me know if you still need help with it & Check Omeka it's possible it fits your need. https://omeka.org/classic/docs/GettingStarted/UsingOmeka/#how-are-others-using-omeka-classic

Solid advice and now I have working features! I was unable to find critical details for my setup until Mohammad took the time to explain the detail and provide specific, working examples. Thank you so much for the help and I recommend any DSpace users that encounter problems to consult this forum and ask detailed and specific questions. Be sure all the context and detail is included. In the case of this thread, Mohammad not only explained what I needed, but he edited and provided the configuration files specific to my system!  This is an important service! Thanks to all the Developers, Mohammad, and all the others who have helped me in the past.
