org.apache.stanbol.ontologymanager.servicesapi.scope.Scope
Represents an ontology network that is used for modelling a given knowledge component or domain, e.g. workflows, organisations, devices, content or business domain.

Each ontology scope comprises in turn a number of ontology spaces of three kinds.
- Exactly one core space, which defines the immutable components of the scope.
- At most one custom space, which contains user-defined components.
- Zero or more session spaces, which contains (potentially volatile) components specific for user sessions.
An ontology scope can thus be seen as a façade for ontology spaces. @author alexdma
