In the TOGAF 9.1 specification: 34.7 Metamodel Relationships (page 368) the following relationships should exist:

1. Function "is bounded by" Service relationship

2. Service "Is realized through" Logical Application Component

Both of these appear to be missing. Can you please add them.

Further, I am not clear how best to model the relationship between a Logical Application Component and the Function(s) it supports

In the TOGAF 9.1 specification: 35.6.5 Phase C: Application Architecture - Application/Function Matrix (page 393)

The Application/Function matrix is a two-dimensional table with Logical Application Component on one axis and Function on the other axis. The relationship between these two entities is a composite of a number of metamodel

relationships that need validating:

- Function is bounded by Service

- Services are realized by Logical/Physical Application Components

The mapping between Application and Function is clearly very useful - and I would like to be able to generate the Application/Function Matrix.

If you could comment on this, and perhaps add it to the next version of the manual (when the missing relationships are added) that would be great. The current TOGAF plug-in manual does not demonstrate the use of Functions - however, modelling a functional decomposition and explaining the mapping to applications is very important.

Thanks
