Yes your approach seems correct here. Cloudron will not overwrite any existing DNS records, so it is safe to add example.org in this case, even if its used elsewhere.
@GeHo said in Omeka S on Cloudron as host for embedded exhibits - CORS:
Because the HTML itself delievered by Omeka loads scripts, images, css etc. from the domain of origin. This causes the CORS issues.
aren't all these covered by same origin policy exceptions ? https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy#cross-origin_network_access
