Description (English):

This part of ISO 10303 specifies a C programming language late binding of the capability specified in ISO 10303-22 - Standard data access interface (SDAI). This binding is a late binding and as such, none of the constants, data types, and functions depend on the application schema being accessed. The following are within the scope of this part of ISO 10303: — access to and manipulation of data types and entities which are specified in ISO 10303-22; — convenience functions suitable to this language binding; — late binding requirements specified in ISO 10303-22. The following are outside the scope of this part of ISO 10303: — memory arrangement of data structures used by implementations of this part of ISO 10303; — early binding requirements as specified in ISO 10303-22; — all items listed as out of scope in ISO 10303-22.

Abstract

Overview

ISO 10303-24:2001 defines the C language late binding for the Standard Data Access Interface (SDAI) of the ISO 10303 (STEP) family. In plain terms, this part of the ISO 10303 suite specifies how C programs can access, query and manipulate product data through SDAI using a late-binding approach - none of the constants, data types or functions depend on the application schema being accessed. The standard targets interoperable product data representation and exchange for industrial automation and PLM systems.

Key Topics

Late binding of SDAI (C binding): runtime access to EXPRESS-schema-based data without schema-specific compile-time types.
SDAI operations exposed in C: environment, session, repository, SDAI-model, schema instance, scope, type, entity instance and application instance operations (create, copy, delete, query, validate, save/undo).
Data types and constants: EXPRESS and SDAI primitive/entity/aggregate types mapped to C-binding types, iterators, non-persistent lists, error codes and convenience data blocks.
Convenience functions & error handling: language-specific helpers and late-binding error handling conventions.
Conformance and naming conventions: requirements for conformant implementations and header/macro usage.
Out of scope: memory layout of implementation data structures and early binding requirements (those are explicitly excluded).

Applications

ISO 10303-24 (C language binding of SDAI) is practical for:

Building interoperability layers between CAD, CAM, CAE and PLM systems that consume STEP (ISO 10303) data in C-based applications.
Implementing data exchange, validation and transformation tools that must work across different EXPRESS schemas at runtime.
Creating custom repositories or SDAI-compliant servers/clients in C that perform queries, instantiation, scoped copy/delete and schema validation.
Embedding STEP access into embedded systems or HPC tools where C is required for performance or platform constraints.

Who would use this standard

Software developers and engineers implementing STEP/SDAI tools in C/C++.
PLM integrators, CAD/CAM software vendors, system integrators, and middleware developers needing schema-independent product data access.
Architects of data repositories and standards-compliant exchange services.
