An IFC View Definition, or Model View
Definition,
MVD, defines a subset of the IFC schema, that is needed to satisfy
one
or
many Exchange Requirements of the AEC industry. The method used and
propagated by buildingSMART to define such Exchange Requirements is
the
Information Delivery Manual, IDM (also ISO/DIS 29481).
An IFC Model View Definition defines a legal subset of the IFC Schema
(being
complete) and provides implementation guidance (or implementation
agreements)
for all IFC concepts (classes, attributes, relationships, property
sets,
quantity definitions, etc.) used within this subset. It thereby
represents
the software requirement specification for the implementation of an
IFC
interface to satisfy the exchange requirements.
Whereas the general
exchange requirement is independent of a particular IFC release, the
realization (or binding) within the model view definition is specific
to an
IFC release.
Model View Definitions are either defined within buildingSMART
International, or by other organizations and interest group. MVD's
defined
externally are not considered as buildingSMART MVD's until they are
submitted
to buildingSMART International, reviewed by the buildingSMART teams
and
finally accepted.
