This document specifies the definition for services at the point of interaction between a client and server.
The following are within the scope of this document:

The following are outside the scope of this document:
—    domain specific services definitions;
—    the transformation of SysML metamodel constructs into OpenAPI constructs that are not used in the STEP extended architecture[12][13];
—    the transformation of SysML metamodel constructs into OpenAPI constructs for other purposes than representing SysML constructs as STEP concepts;
—    codes and scripts to transform SysML XMI to OpenAPI schema;
—    the transformation of SysML constraints into OpenAPI schema;
—    implementation of technology-specific services definitions other than RESTful OpenAPI;
—    definition of management and maintenance of information and data on a server.
