3. Background

4. IT Evolution Objective: Provide On-demand Services for Users (Developer/End User)

5. Service is Flourishing… IaaS Infrastructure as a Service PaaS Platform as a Service SaaS Software as a Service SOA Cloud Computing ： XaaS

6. 6 Meet in Middle On-demand Service Provision RGPS Metamodels RGPS Metamodels Computing service Networked Environment Requirements Elicitation and Analysis Common requirementsPersonalized requirements Software Service Service Aggregation Platform Service Storage Service Service Oriented User Centric

7. 7 Objectives of RGPS RGPS provides a framework for the management,discovery and sharing of service- related models.  RGPS consists of several views of services, which can be used to capture user’s requirement.  According to the mapping between user’s requirement and the RGPS registration information, appropriate models/services can be selected to satisfy user’s intention.  Semantic annotations will be used to express the relationship between service-related models and domain ontologies.
