TLDR
This paper introduces an extended service oriented architecture that provides separate tiers for composing and coordinating services and for managing services in an open marketplace by employing grid services.Abstract:
Service-oriented computing (SOC) is the computing paradigm that utilizes services as fundamental elements for developing applications/solutions. To build the service model, SOC relies on the service oriented architecture (SOA), which is a way of reorganizing software applications and infrastructure into a set of interacting services. However, the basic SOA does not address overarching concerns such as management, service orchestration, service transaction management and coordination, security, and other concerns that apply to all components in a service architecture. In this paper we introduce an extended service oriented architecture that provides separate tiers for composing and coordinating services and for managing services in an open marketplace by employing grid services.read more

Policy-based contracting in semantic web service markets
TL;DR: An automated contracting mechanism that includes algorithms for automated matching, allocation, contract formation and contract monitoring is introduced and indicates that Web service contracting is applicable in practice and that semantic matching of requests and offers is particularly important for settings with highly customizable services.

Digital Ecosystems
TL;DR: In this article, the authors presented the Digital Ecosystem, a novel optimisation technique inspired by biological ecosystems, where the optimisation works at two levels: a first optimisation, migration of agents which are distributed in a decentralised peer-to-peer network, operating continuously in time; this process feeds a second optimisation based on evolutionary computing that operates locally on single peers and is aimed at finding solutions to satisfy locally relevant constraints.

Modeling Service Oriented Architectures of Mobile Applications by Extending SoaML with Ambients
Nour Ali,Muhammad Ali Babar +1 more
TL;DR: An approach is presented, which introduces ambients in Service oriented architecture Modeling Language (SoaML) proposed by the OMG in order to allow its models to include mobility primitives, and demonstrates the use of SoaML for modeling SOA of a mobile application.

Granularity of Services – an Economic Analysis
TL;DR: The aim of the decision model proposed in this paper is to determine an adequate granularity of services from an economical perspective, and degrees of freedom, which often exist for the choice of granularity after a domain analysis, can be leveraged to realize a cost-efficient solution.

Business process execution language for web services
TL;DR: This book focuses on executable processes and comes back to abstract processes in Chapter 4, which can be used to replace sets of rules usually expressed in natural language, which is often ambiguous.

Grid services for distributed system integration
TL;DR: In this paper, the authors focus on the nature of the services that respond to protocol messages and propose a set of services that can be aggregated in various ways to meet the needs of virtual organizations, which themselves can be defined by the services they operate and share.
Web Services Coordination (WS- Coordination)
TL;DR: This specification describes an extensible framework for providing protocols that coordinate the actions of distributed applications, used to support a number of applications, including those that need to reach consistent agreement on the outcome of distributed transactions.
Grid Service Specification
TL;DR: Technical details are provided, providing a full specification of the behaviors and Web Service Definition Language (WSDL) interfaces that define a Grid service.

Design Methodology for Web Services and Business Processes
Mike P. Papazoglou,Jian Yang +1 more
TL;DR: This paper presents a design methodology for web services and business processes and discusses how business process should be described so that services can be properly identified and provide strategies and principles regarding functional and non-functional aspects of web service design.
