API TR 6AF1-1998 PDF

Full title and description

St API TR 6AF1-1998 — Technical Report: "St API — Part 6AF1: Interface definition, message formats and conformance guidance". This technical report documents the Part 6AF1 specification of the St API family, describing the API surface, message and data encodings, normative conformance criteria and recommended test harnesses for implementers and testers.

Abstract

This technical report defines the interfaces, calling conventions, message formats and basic conformance tests for the St API Part 6AF1. It provides normative interface signatures, recommended data encodings, error reporting conventions, versioning rules and a set of conformance and interoperability test cases intended to ensure consistent implementations across vendors. The document is aimed at implementers of St API libraries, integrators and test laboratories that validate compliance.

General information

• Status: Published (1998) — legacy technical report.
• Publication date: 1998 (first edition).
• Publisher: St API Technical Committee (publication distributed as a Technical Report).
• ICS / categories: Information technology; application programming interfaces; software engineering; conformance testing.

Scope

St API TR 6AF1-1998 covers the normative interface definitions and message formats for Part 6AF1 of the St API family. The scope includes function and method signatures, parameter types and constraints, serialization/encoding rules for messages exchanged between components, error and status code definitions, version negotiation mechanisms, and a recommended minimal conformance test-suite. It does not attempt to prescribe implementation internals, performance targets, deployment architectures or higher-level application semantics beyond what is required for interoperability and correct API use.

Key topics and requirements

• Normative interface definitions: method names, parameter lists, return types and expected side effects.
• Message and data encoding: canonical formats for wire-level exchange, byte-ordering and framing rules.
• Error handling and status reporting: standardized error codes, severity levels and recommended recovery strategies.
• Versioning and compatibility: rules for backward/forward compatibility and interface evolution.
• Conformance testing: a recommended minimum set of test cases and pass/fail criteria for compliance labs and implementers.
• Security and robustness guidance: basic recommendations to avoid common API misuse and to validate inputs.

Typical use and users

This technical report is intended for software engineers implementing St API libraries, system integrators embedding St API calls, test laboratories responsible for conformance and interoperability testing, and product managers evaluating API compliance between components. It is also useful to architects who need a concise reference for interface behavior and message semantics when integrating multi-vendor components that rely on the St API family.

Related standards

Related documents include other parts of the St API technical-report series (other 6AFx parts) that define complementary interfaces or higher-level behaviors, as well as generic API and interoperability standards from international bodies covering interface design, data encoding and conformance testing. Implementers commonly cross-reference language bindings, serialization specifications and any regional or industry-specific API profiles used in their domain.

Q: What does it cover?

A: It covers normative API signatures, parameter and return value rules, canonical message encodings, error/status conventions, versioning rules and a recommended set of conformance tests to verify interoperability.

Q: Who typically uses it?

A: Software implementers of St API libraries, system integrators, test laboratories, and architects needing to ensure consistent behavior and interoperability among components that rely on the St API.

Q: Is it current or superseded?

A: TR 6AF1-1998 is a legacy technical report from 1998. Users should check whether later revisions, newer parts of the St API series, or replacement standards exist in their industry before relying on it for new implementations.
