Access to the data stored in a SEDRIS transmittal is through an Application Program Interface (API). The abstract specification for this API is defined in ISO/IEC 18023-1. Each part of ISO/IEC 18024 defines the binding of that abstract specification to a particular programming language. ISO/IEC 18024-5 will define a standard binding for the C++ programming language. This work will: • Leverage the existing standard 18024-4, SEDRIS language bindings – Part 4: C • Include other improvements that may be identified by JTC 1/SC 24 during the development of this work item.
