We call CORE a 'universal resource management system' because with the few fundamental concepts that we invented to solve our own diverse business needs, we see new usecases through our users all the time.
One such case is to use CORE as a membership management system.
Think of it this way: a annual membership is really just a 'service for 12 months'; and so if we simply create a 'Resource' as the tier-name of a membership, for example 'VIP', with a primary tag as 'membership', and secondary tag 'vip', we could build up a 'booking flow' that sells membership 24/7, also visualizing all of your members in the matrix showing you their 'membership term'.
