New IEEE Standard - Inactive - Withdrawn.Withdrawn Standard. Withdrawn Date: Mar 06, 2000. No longer endorsed by the IEEE. 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.
