The Fulcrum ResourceManager Services manages multiple ResourceManager. Each ResourceManager is responsible for exactly one domain. Therefore the Fulcrum ResourceManager Services just delegates the method invocations to the various ResourceManagers.
The resources are located in a domain. A domain definition contains the location of the hierarchical resources, a suffix to filter resources based on their externsion and a flag for using the locator feature
It is not possible to define a domain more than once since each domain has a unique name. But it is possible to use different domain names and share a location using a suffix filter.
