ISO/TS 10303-18:2021 (R2025)

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 specification of the structure, components and conventions for domain- and technology-independent services implementation methods for STEP (ISO 10303-1); — transformation of the SysML metamodel constructs to OpenAPI constructs for RESTful web services (see OpenAPI:3.0.0[25] and IETF RFC7231). 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.
