FAQs

Where can users find further information on feature topology in the DRM?
See P4V4
of the SEDRIS Documentation Set for further information.

Why can't a
<Reference Surface> instance
be associated to a
<Feature Hierarchy> instance,
as with <Geometry Hierarchy> instances?
A <Reference Surface> instance is associated
to a <Geometry Hierarchy> instance to
indicate that the
<Geometry Hierarchy> instance represents
a reference surface. <Feature Hierarchy>
instances are not used to represent reference surfaces.

Notes
Associated to Notes
An association between two
<Feature Representation> instances
indicates that the environmental object(s) that they
represent have the semantic relationship indicated by
the <Base Association Data>
link object on the association relationship.
An association between a
<Geometry Hierarchy> instance and a
<Feature Representation> instance
indicates that the environmental object(s) that they
represent have the semantic relationship indicated by
the <Base Association Data>
link object on the association relationship.
An association between a
<Property Grid> instance and a
<Feature Representation> instance
indicates that the environmental object(s) represented by the
<Feature Representation> instance
and the <Property Grid> instance
(or some specific cell data within that
<Property Grid> instance) have the
semantic relationship indicated by the
<Base Association Data> link object
on the association relationship. Each associated
<Property Grid> instance indicates
whether the entire <Property Grid>
instance or only some specific cell data within it is participating
in the relationship in question.
