The document presents the 4 x 4 semantic model for unifying the four tiers of business process modeling - business process tier, workflow enactment tier, partner services tier, and middleware services tier - using four types of semantics - data, functional, non-functional, and execution semantics. It describes each tier and type of semantics, and proposes using semantic templates annotated with standards like SAWSDL and policies to integrate the tiers and relate their components semantically. This allows for capabilities like dynamic service discovery, composition, execution, adaptation and mediation across the tiers.

Notes de l'éditeur
- In Role of Semantics for Workflow Enactment Tier: change consistence to consistency. In Technologies for Business Process Tier, add BPMN
- What Who point: In the insurance example, the fact that we need a DMV partner, a credit bureau and cc processing are identified. Who are the actual partners that we will bind to is not. This is deferred to execution time. This is important to understand the dynamism of the 4 X 4.

- This picture illustrates the coming together of the 4 tiers of business process and how the 4 types of semantics facilitates this. At the heart of this modeling, is the grounding to ontologies. Further this slide also illustrates the interaction between the different tiers. The specifications in the process tier are enacted as workflows in the enactment tier. These workflows are deployed in a middleware that provides deployment and messaging services. The partner services are also deployed in middleware systems. In addition to these, the middleware services tier providers services such as discovery and mediation and message routing. Process Modeling Tier: Conventional workflow specifications or Mashup/Smashup specifications are captured at this tier. Conventional workflow specifications are captured using semantic templates for SOAP services while Smashup specifications are captured using micro-format enhanced SAREST. Workflow Enactment Tier: Based on the process level specifications, partner level specifications are created and workflows are enacted with these partner level specifications. The various tasks in the workflow are described by the operations in the corresponding semantic template. For example, in a supply chain workflow for procuring various components, the partner level specifications for each component is captured. A workflow is then created where a task corresponding to a functional requirement in the partner level specifications. In the context of light weight services, Smashups are created to enact out service compositions. Service compositions are captured as client side objects, which are annoated with micro formats. The service at the server side based on the semantics of the client side objects that are sent to it, invokes the relevant services in the order while making sure of the interaction and role. Service discovery and process configuration is done using the partner level specifications. Adaptation strategies such as events that are relevant, event subscription and notification management are done based on the functional and non-functional processs and partner level specifications. Partner service tier: IN the classical service context, partner services capture their capabilities and requirements in SAWSDL. In case of light weight services, annotated pages with RDFA and annotated XML inputs/ output allows for publication and discovery of these services. Middleware Services Tier: The capabilities of the middleware to support semantic web services, deployment, message processing, event handling and data mediation can be captured. As we can see in the example, the middleware services tier provides container services for both the enacted workflow as well as for partner services.
