A  Behavior Type is an Operating Asset Type that describes any action or reaction of an Agent Type to external or internal Behavioral Events.  Behavior Types include Action Process Typees (action), Interaction Process Types (stories) or interactions (Service Interface).

The course of actions of a  Behavior Type is constrained ( Rule Enforcement) by the application of Behavioral Rules that define what is allowed and not allowed to do.

An  Entity is a distinct, identifiable Element that has a proper existence (living or non living). It is accessible by some referencing mechanism and can establish elementary relationships (Relationship) to other  Entitys.

The  Entity class is the powerinstance of Class of Entity: all subtypes of  Entity are instances of Class of Entity.

A  Container is a collection of Building Blocks whose existence and meaning are defined by the  Container.

A  Container is both:

1. A Lexical Scope: the meaning and usage of a Building Block is only applicable within the context of the  Container to which it belongs.

2. A universe of discourse: the complete range of Building Blocks that are expressed, assumed, or implied in an architecture domain.

Examples:

- Container Package

- Library

- Enterprise

An  Agent Type is an Operating Asset Type which is able to participate actively to Behavior Types, to produce and react to Outcome Events.

1.  Agent Types participate to Action Process Typees (Active Participant) and/or conduct Action Process Typees (Performed Process).

2.  Agent Types participate to Interaction Process Type (Scenario Participant) describing how they interact with other  Agent Types.

These actions and interactions define  Agent Types boundaries described by Service Interfaces.
