This document discusses service-oriented architecture modeling language (SOAML) and how to identify services. It defines what a service and capability are, and describes techniques like goal-service modeling, domain decomposition, and existing asset analysis to identify capabilities. The SOAML methodology involves identifying services and specifying them through diagrams like capability uses, participant capability, service architecture, and service contract. The implementation steps are then outlined as service identification, specification, and design phases involving models to define capabilities, participants, dependencies, and components. Examples of capability uses and participant capability diagrams are provided.

SERVICE IDENTIFICATION

2. AGENDA
• What is A Service ?
• What is A Capability ?
• How to identify service capability ?
• SOAML methodology
• Steps for SOAML Implementation

3. WHAT IS A SERVICE
• A value delivered to another through a well defined interface
• A Business or capability that exposed by its provider
• Set of capabilities that collaborate to make specific purpose
• Any thing in enterprise represents a service

4. WHAT IS A SERVICE CAPABILITY
• The ability to do something
• Identifies a cohesive set of functions or resources provided by one or more
participants
• Ability to act and produce an outcome that achieves a result
• Capabilities are used to identify candidate services
• Can specify a general capability of a participant as well as the specific ability
to provide a service
• Allows architects to analyze how services are related and how they might be
combined to form some larger capability prior to allocation to a particular
Participant

5. HOW TO MODEL SERVICE CAPABILITY
Capability can be identified using the following techniques
Goal-service modeling [strategies and goals]
Identifies capabilities needed to realize business requirements
Domain decomposition [Business Process]
Uses activities in business processes and other descriptions
of business functions to identify needed capabilities
Existing asset analysis [existing]
Discover capabilities from existing applications

METHODOLOGY

7. STEPS FOR SOAML IMPLEMENTATION
1. Service Identification
2. Service Specification
Model Description
Capability Uses Diagram Identify Capabilities
Exposing appropriate capabilities as services
Participant Capability Diagram Define participant that provide capabilities
Model Description
Service Architecture Diagram Defining the architecture for how the services
interact
Service Contract Diagram
Service Interface Diagram
specify the services, design their interfaces which
providers provide what services and how
Provider/Consumer
[Dependency – sequence flow)
Specify the dependency between provider and
consumer and sequence flow between them
Message Type Diagram Define specification of information exchanged
between service consumers and providers.

3. Service design
Model Description
Participant Dependency Diagram dependencies among the service participants and
establishes the coupling in the system
Participant Components Diagram Define the inner component and relationship within
specific participant
