This metamodel supports the definition of services. The Business Services is so named to establish the distinction with the IT services. Even though business services can be supported by the IT, at this level the metamodel addressed the business perspective of the services and not the technical aspects.

A category property enables the classification of NAF Services (operational, information, application).

Services can be derived from existing objects to focus on the differences instead of replicating all the existing sub-items (variable object).

A service can be linked to the constraints that must be supported.

A service can be decomposed into sub-services (business service composition).

As an interacting element the business service compositions can be linked to each other through interactions that express the data exchanged.

As an Interacting Physical Resource, the business service can expose services and request points that match the accessible service interfaces.

Finally, important property values can be added to emphasize some characteristics of the services.
