I find it very tempting to go for the “one Omeka S to rule them all” scenario, and build all exhibits based on a single instance. After all this seems to be one of the driving ideas behind the project.
I feel however that this can lead to confusion as we add modules and themes, users experiment with items, resource templates, etc. Things can become quite bloated and confusing. Permissions do not always allow us to separate projects the way users would want, etc.
I am curious to know what people have been doing to manage this! Which approach seems the right one to you and why?
