scope:

This standard is an implementation-independent specification for a software interface to information systems containing data pertinent to the diagnosis and maintenance of complex systems consisting of hardware, software, or any combination thereof. These interfaces will support service definitions for creating application programming interfaces (API) for the access, exchange, and analysis of historical diagnostic and maintenance information. The standard will use the information models of IEEE Std 1232 as a foundation.

Purpose

The purpose of this standard is to specify a software interface for access, exchange, and analysis of product diagnostic and maintenance information. This will address the pervasive need of organizations to assess the effectiveness of diagnostics for complex systems throughout the product life cycle. The use of formal information models will facilitate exchanging historical maintenance information between information systems and analysis tools. The models will facilitate creating open system software architectures for maturing system diagnostics.

Application

This standard should be applied in the development of software applications that access or provide information relevant to the diagnosis and maintenance of systems. In the event of conflict between this standard and a component standard in the IEEE 1636 family, the component standard shall take precedence. In the event of conflict between this standard and a related standard such as IEEE Std 1232, the standard as it applies to the information being produced shall take precedence. In the event of any conflict between model comments and lexical definitions, lexical definitions shall take precedence.

Conventions used in this document

Clause 5 presents entity and concept definitions using the EXPRESS language as defined in ISO 10303- 11:1994 and uses the following conventions in their presentation:

All specifications in the EXPRESS language are given in the Courier type font when model elements are represented outside the scope of the model.

This standard uses the vocabulary and definitions of relevant IEEE standards. In case of conflict of definitions, the following precedence shall be observed: 1) Clause 3, Definitions; 2) The Authoritative Dictionary of IEEE Standards Terms [B1]2 with preference given to versions of those definitions that are attributed to SCC20 standards
