Abstract: Based on the development of Web Services and grid,the reason of emergence of WSRF is introduced.Then the detailed content of WSRF is described and finally WSRF and OGSI,WSRF are compared respectively.
The Convergence of Grid and Web Services-WSRF and WS-Notification

LIU Hui-Bin,DU Zhi-Hui,

计算机科学 , 2005,
Abstract: The WS-Notification specification and the WS-Resource Framework (WSRF) provide a scalable publish/ subscribe (pub/sub) messaging model and the ability to model stateful resources using Web services. In this paper, the relationhip between OGSI and the WSRF is introduced first. WSRF can be viewed as a straightforward re factoring of the concepts and interfaces developed in the OGSI version 1.0 specification. WSRF tries to model Stateful Re- sources with Web Services Resource approach to declaring and implementing the association between a Web service and one or more named typed state components. An approach is described for making the properties of a WS-Re- source accessible through its Web service interface and for managing a WS-Resource's lifetime. The discussion on how a pub/sub notification mechanism (WS-Notification) can be built on top of the WS Resource framework is also given. Finally,this paper also presents a summary of WSRF and WS-Notification briefly and a simple discussion on the future research.
Design Web Services: Towards Service Reuse at the Design Level  [cached]
Wang Chu,Depei Qian
Journal of Computers , 2009, DOI: 10.4304/jcp.4.3.193-200
Abstract: Service oriented software development has gained more and more importance in the area of e-business. Most researchers focus on the semantic description of Web services and automated composition but pay little attention to how to design Web services for supporting service reuse effectively, thus a substantial amount of modeling and programming is still required. In this paper, a pattern oriented service design method is presented by which all components of different abstraction levels are uniform in regard to their specifications and composition mechanism. Pattern oriented service design model provides a traceable and explicit link from business components to software components so that the top-down service reuse at design level is supported, and the service maintainer profits from the traceability because the impact of requirement or design modifications can be better assessed. The semantic information of component specification can support semantics based component reuse. The pattern oriented service design model can improve development productivity by offering a better chance of reuse through better modularity.
Customized Information Service Based on WSRF

International Journal of Computer Trends and Technology , 2011,
Abstract: This paper discusses the research methodology on Web Services Security Architectures for Secure Service Oriented Analysis and Design. Initially we discuss about the Research Methodology for Designing Dependable Agile Layered Security Architecture Solutions for Web Services Security Architectures. Finally we discuss an implementation case study of ensuring data security architecture on Web Services Cloud
Towards Automation Design Time Testing of Web Service Compositions  [PDF]

e-Informatica Software Engineering Journal , 2012,
Abstract: Service-Oriented Architectures (SOA) allows software applications to interoperate in a new way in distributed environment. Currently, web services are the most widely adopted technology for implementation of SOA. However, they bring a number of challenges to development as well as to testing. Testing web service compositions is one of the major problems in SOA domain that is due to the unknown context, absence of web service source code, multiple provider coordination,lack of tool support, etc. In such context, the paper proposes a framework, named Testing as a Service Software Architecture (TASSA), which aims to provide design time testing of both functional and nonfunctional behavior of web service compositions described with Business Process Execution Language (BPEL). TASSA consists of set of tools that can be used together with existing development environments of service based applications. The paper focuses on an approach for negative testing and unit testing of BPEL processes. The negative testing is supported by TASSA tool, called Fault Injector tool, which implements a fault injection technique providing messagedelays, wrong message data, etc. The goal of unit testing is to test a BPEL process in isolation from its dependent web services. The isolation technique is implemented in another TASSA tool, named Isolation tool.
Grid Resources Management Based on WSRF

Zhu Yaling Bi Qiang Han Yi,

现代图书情报技术 , 2006,
Abstract: This paper introduces the WS-Resource Framework(WSRF) using the technology of Web Service.An approach is also described for managing Grid resources through modeling stateful resources,making a WS-Resouce's properties by Web Service interface and controlling a WS-Resouce's lifetime.

Abstract: The WS-notification specification and the WS-resource framework provided a scalable publish/subscribe messaging model and the ability to model stateful resources using Web serivces.After describing the specification of WSRF,how to build a grid services on top of the WS-resource framework with GT4 were explained.
Design and implementation of smart home system based on OSGi home gateway and Web Service
基于OSGi家庭网关和Web Service技术的智能家庭系统

SONG Ya-li,TANG Xiao-sheng,

计算机应用 , 2007,
Abstract: The Open Service Gateway Initiative (OSGi) Home Gateway can provide mobile users with various services, including smart home management, remote control, etc. Meanwhile, Web Service makes it possible for any application system to access dynamically all kinds of services anywhere. However, current solutions for smart home are mostly based on home gateway, without taking Web Service into account. Therefore, this paper proposed a new design and implementation for smart home combining OSGi Home Gateway with Web Service technology. Based on the detailed design of the system modules, this paper also gave the result of accessing the OSGi Web Service by PDA to supervise the status of home appliances.
Composite Design Pattern for Feature Oriented Service Injection and Composition of Web Services for Distributed Computing Systems with Service Oriented Architecture
Vishnuvardhan Mannava,T. Ramesh
International Journal of Web & Semantic Technology , 2012,
Abstract: With the advent of newly introduced programming models like Feature-Oriented Programming (FOP), we feel that it will be more flexible to include the new service invocation function into the service providing server as a Feature Module for the self-adaptive distributed systems. A composite design patterns shows a synergy that makes the composition more than just the sum of its parts which leads to ready-made software architectures. In this paper we describe the amalgamation of Visitor and Case-Based Reasoning Design Patterns to the development of the Service Invocation and Web Services Composition through SOA with the help of JWS technologies and FOP. As far as we know, there are no studies on composition of design patterns for self adaptive distributed computing domain. We have provided with the sample code developed for the application and simple UML class diagram is used to describe the architecture.
