IEEE 1516.2-2025

This document defines the format and syntax for recording information in High Level Architecture (HLA) object models, to include objects, attributes, interactions, and parameters. It does not define the specific data (e.g., vehicles, unit types) that will appear in the object models.

The HLA has been developed to provide a common architecture for distributed modeling and simulation. The HLA requires that federations (sets of federates) and individual federates (simulations, supporting utilities, or interfaces to live systems) be described by an object model that identifies the data exchanged at runtime to achieve federation objectives. This standard defines the documentation of the object model.

Revision Standard - Active. The High Level Architecture (HLA) has been developed to provide a common architecture for distributed modeling and simulation. The HLA defines an integrated approach that provides a common framework for the interconnection of interacting simulations. This document, the third in a family of three related HLA documents, defines the format and syntax (but not content) of HLA object models. The standards contained in this architecture are interrelated and need to be considered as a product set, when changes are made. They each have value independently.
