RGPS Overview

This overview introduces the RGPS framework, which enables personalized service provision and aggregation in a networked environment. Through RGPS metamodels, the system captures, analyzes, and maps user requirements to services efficiently. Semantic annotations express relationships between service models and domain ontologies, enhancing service selection. RGPS also integrates with RM-ODP standards for enhanced interoperability. Explore the objectives, metamodels, and tools of RGPS for effective on-demand service delivery.

  3. Background

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

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

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

  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.

  8. RGPS Metamodels

  9. RGPSMetamodels R G P Metamodel of Process Registration S Metamodel of Service Registration 9 Metamodel of Role and Goal Registration

  10. A simple example of RGPS MFI-8 MFI-5 MFI-7 Role Housewife Cook delicious food Goal Process Service
