scope:

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.

Purpose:

The HLA has been developed to provide a common architecture for 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.
