IEEE Std 1224-1993 IEEE Standard for Information Technology—Open Systems Interconnection (OSI) Abstract Data Manipulation—Application Program Interface (API) [Language Independent] -Description
Abstract: A general-purpose application program interface (API) for the creation, examination, modification, and deletion of potentially complex Open Systems Interconnection (OSI) information objects is defined in terms that are independent of any particular programming language. The API provides tools for manipulating objects defined using Abstract Syntax Notation One (ASN.1), shielding the application programmer from much of the complexity of ASN.1. It is designed to be used in conjunction with, but is otherwise independent of, application-specific APIs for OSI.
Keywords: abstract syntax notation, API, application portability, ASN.1, language independent, object management, open systems, open systems interconnection, OSI
