1 Scope
This document specifies a mapping of EXPRESS (ISO 10303–11) constructs to SysML constructs for the purpose of representing EXPRESS schemas in
SysML models. The specified mapping is a one-way transformation from an EXPRESS schema
to a SysML information model.
The following are within the scope of this document:
-
— the specification of the transformation of EXPRESS constructs to SysML constructs
represented in CXMI;
-
— the specification of the transformation of EXPRESS UNIQUE rules to SysML constructs
represented in CXMI;
-
— the specification of the transformation of derived attributes to implement renaming
to SysML constructs represented in CXMI.
The following are outside the scope of this document:
-
— the transformation of EXPRESS elements into SysML metamodel constructs that are not
used in the STEP Extended Architecture[9][10][11];
-
— transformation of EXPRESS FUNCTIONS;
-
— transformation of EXPRESS-G to SysML diagrams;
-
— tools, codes, and scripts to transform an EXPRESS schema to SysML CXMI;
-
— transformation of EXPRESS interface specification;
-
— SysML constraints transformation from EXPRESS DERIVE attributes, except the ones used
for renaming;
-
— SysML constraints transformation from EXPRESS SUPERTYPE expressions;
-
— SysML constraints transformation from EXPRESS GLOBAL rules;
-
— SysML constraints transformation from EXPRESS WHERE rules.
NOTE EXPRESS DERIVE attributes, EXPRESS SUPERTYPE expressions, EXPRESS GLOBAL rules and
EXPRESS WHERE rules are transformed into OCL[2] specifications. OCL specifications are integrated in the SysML model based on a separate
process.
