Service Oriented Architecture (SOA) promises to reduce coupling between components in an enterprise.  However, practitioners are finding that unless the semantic issues are addressed, the tight coupling persists, merely moved from the binding layer to the terminology layer.

In this tutorial we introduce the concept of an Enterprise Message Model as the mediation layer between applications and services.  We will show how the Enterprise Message Model is derived from an Enterprise Ontology, and how specific service invocations are defined from the Enterprise Message Model.  This tutorial will include:

• A Methodology for Creating and using an Enterprise Message Model
• A set of patterns for composition and deployment of applications in such an environment
• Guidelines for what to include in the shared ontology, and what should remain in the local ontologies of each application

This tutorial represents pragmatic advice from practitioners who have applied this approach successfully in several client engagements.
