3 Terms, definitions and abbreviated terms

3.1 Terms and definitions

3.1.1 Terms defined in ISO 10303-1

For the purposes of this document, the following terms defined in ISO 10303-1 apply:

application interpreted model;
integrated resource;
application;
application context;
application interpreted construct;
application protocol;
implementation method;
interpretation;
product data.

3.1.2 Terms defined in ISO 10303-42

For the purposes of this document, the following terms defined in ISO 10303-42 apply:

arcwise connected;
axi-symmetric;
bounds;
boundary;
coordinate space;
curve;
domain;
extent;
open curve;
orientable;
surface;
topological sense.

3.1.3 Terms defined in ISO 10303-511

For the purposes of this document, the following terms defined in ISO 10303-511 apply:

advanced face.

3.1.4 Other terms and definitions

For the purposes of this document, the following terms and definitions apply:

3.1.4.1
connected face subset

set of arcwise connected faces whose domain is a portion of the domain of an existing connected face set

NOTE In this part of ISO 10303, a connected face subset is also required to be of type open shell.

3.1.4.2
manifold subsurface shape representation

shape representation containing connected face sub sets in the form of open shells

NOTE Each open shell has a domain that is part of the domain of another connected face set. The faces of the connected face sub set can be defined as subfaces.

3.1.4.3
subedge

edge whose domain is a connected portion of the domain of another edge

3.1.4.4
subface

face whose domain is a connected portion of the domain of another face

NOTE In this part of ISO 10303 a subface has a domain which is part of the domain of an advanced face.

3.2 Abbreviated terms

For the purposes of this document, the following abbreviated terms apply:

URL	uniform resource locator
AIC	Application Interpreted Construct
AP	Application Protocol
