Functional Schema
Alias: func
Version: 1.0.4
The Functional schema defines common base classes to be used by discipline-specific functional domains.
The Functional domain schema contains the core classes that define the "Functional" Modeling Perspective.
The "Functional" perspective sees an Object not as a physical Entity with form and mass, but as a functional Entity that will perform some activity when in use.
They say "form follows function". Separating the "Functional" perspective from the "Physical" perspective allows independent modeling of "form" and "function". Functional modeling/planning can occur first and be handled by a different responsible party than physical modeling. There is generally more than one physical Entity that could fulfill a given function. The particular physical Entity may be refined throughout the design process and may be changed over the lifetime of the operation of the Object.
The Functional Modeling Perspective is abstract. Domain authors are expected to specialize FunctionalPartition, FunctionalModel, and one or more of the subclasses of FunctionalElement to express their discipline's particular needs for functional modeling, e.g. architectural functional programming or plant process modeling.

FunctionalElement (Functional Element) Abstract EntityClass
A func:FunctionalElement models required functionality that will ultimately be fulfilled by a physical Entity.
Base Class: BisCore:RoleElement
Models a particular functional Entity--something that will perform a particular activity when in use. Functional Entities are non-geometric in nature, and are considered to be 'roles' played by an Object.
