Background

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

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

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.

Relationship with RM-ODP

What is ODP RGPS will not cover all the aspects of information systems RGPS focuses on the management and sharing of domain models. It aims to promote the interoperation between systems.
