We have multiple groups wanting to use Omeka. Are people using a single instance that is used across multiple groups or are people running multiple instances - one for each group?
What are the benefits/costs of single or multiple instances?
The main thing I see with one instance for multiple groups is the usability of browsing and managing items decreases as more groups add items. The up side is that groups can reuse items and reduce duplicate work.
I read that running multiple instances with one database might be the best option. Is this what is advised?
Thanks in advance.
