Conceptual modelling methods such as Object-Role Mod-
elling (ORM) have traditionally been developed with the aim of providing
conceptual models of databasestructures. More recently, however, such
modelling languages have shown their use for modelling(the ontology)of
domains in general.In these latter cases, the modelling effort results in a
(formally based) conceptual reasoning systems using a domain calculus
on top of a domain grammar.
As the title suggests, this paper is primarily concerned with the application of ORM rigour to the modelling of active domains. In doing so, we
will position the logbook paradigm as a history-oriented extension of the
traditional natural language approach of ORM, and define an accompanying domain calculus (the Object-RoleCalculus)which is suitable to deal with active domains.Finally,we will show how specific views
(with dedicated notations), which zoom in on different aspects (such as flow of activities and act or involvement) of active domains, can easily be
derived.
