whitepaper Automatically Determining Compatibility of Evolving Services2008-05-21 Hewlett-Packard
  A major advantage of Service-Oriented Architectures (SOA) is composition and coordination of loosely coupled services. Because the development lifecycles of services and clients are de-coupled, multiple service versions have to be maintained to continue supporting older clients. Typically versions are managed within the SOA by updating service descriptions using conventions on version numbers and namespaces. This paper describes a method to automatically determine when two service descriptions are backward compatible. They then describe a case study to illustrate how they leveraged version compatibility information in a SOA environment and present initial performance overheads of doing so.

whitepaper Service Oriented Architecture to Manage Units of Learning Based on the IMS LD Specification2008-05-16 University of Santiago de Compostela
  A learning design describes the method that enables learners to achieve learning objectives after carrying out a set of activities using the resources of an environment. Among the current proposals, the IMS Learning Design (IMS LD) (IMS Consortium, 2003) specification has emerged as the de facto standard that facilitates the representation of learning designs independently of the chosen pedagogical focus. Nowadays, the CopperCore engine is the most used platform available for executing IMS LD learning designs.

whitepaper The Information Perspective of SOA Design, Part 7: The Execution Approach for the Data Quality Analysis Pattern in SOA2008-05-08 IBM
  This is the seventh paper in a series called the "The Information Aspect of SOA Design." The purpose of this paper is to demonstrate to an architect community the execution approach of detailed data quality analysis in the context of an SOA environment. This paper focuses on the implementation of data quality analysis regardless of the specific technology in use, and will be followed by a related paper that describes in more detail how the related IBM products (WebSphere Information Analyzer) can be used in this context.

whitepaper Distributed Manufacturing With SAP and Cisco: Extending Visibility Across the Global Manufacturing Environment2008-05-01 Cisco Systems
  To compete in today's dynamic business environment, global manufacturing organizations must be able to respond to rapidly changing market and operational conditions. Distributed Manufacturing with Cisco and SAP integrates two proven technologies to offer real-time visibility and collaboration across widely distributed processes to rapidly address critical business events. The combination of SAP's Manufacturing Integration and Intelligence (SAP MII) application and the Cisco Service Oriented Network Architecture (SONA) provides secure connectivity between multiple locations and enterprises, and improves the quality and effectiveness of communications between decision makers.

whitepaper The eight most important best practices in SOA governance2008-05-01 Hewlett-Packard (HP)
  The technologies used by IT to create Service-Oriented Architectures (SOAs) are maturing. They are found to be robust and reliable. SOA governance provides a framework for making and applying the decisions that determine how the SOA will be designed, developed and operated. Work with real enterprises deploying SOAs to solve real business problems has led to the development of a set of best practices spanning SOA. This paper presents the eight best practices for SOA governance.

whitepaper Multiobjective Optimization of SLA-Aware Service Composition2008-04-25 University of Massachusetts
  In Service Oriented Architecture, each application is often designed as a set of abstract services, which defines its functions. A concrete service(s) is selected at runtime for each abstract service to fulfill its function. Since different concrete services may operate at different Quality of Service (QoS) measures, application developers are required to select an appropriate set of concrete services that satisfies a given Service Level Agreement (SLA) when a number of concrete services are available for each abstract service. This problem, the QoS-aware service composition problem, is known NP-hard, which takes a significant amount of time and costs to find optimal solutions (optimal combinations of concrete services) from a huge number of possible solutions.

whitepaper Develop and Deploy Multitenant Web-Delivered Solutions Using IBM Middleware, Part 1: Challenges and Architectural Patterns2008-04-24 IBM
  Web-delivered solutions that follow a Software as a Service (SaaS) delivery model - where customers subscribe to software and access it from a service provider site rather than get licenses and have software installed on their premises - can offer compelling business value for businesses of any size. Solution developers who develop new solutions or transform existing solutions and service providers who deploy these solutions are faced with several technical challenges. One example is multitenancy, where a single instance of the software, running on a service provider's premises, serves multiple organizations. This paper series describes different patterns to address these challenges, often using Service-Oriented Architecture (SOA) techniques. Also learn how IBM software products can help one build and deploy scalable, configurable, and cost-effective multitenant Web-delivered solutions.

whitepaper SOA Governance, Organization2008-04-18 IT.com
  SOA (Service Oriented Architecture) Governance is an essential ingredient for SOA success. The paper has discusses what governance is comprised of, how policies implement an SOA governance model, and how these policies can be enforced using technology solutions. The paper also discusses an approach to developing an SOA governance model and the required policies to achieve business and technology objectives. SOA governance is critical to SOA success.   
whitepaper The Information Perspective of SOA Design, Part 6: The Value of Applying the Data Quality Analysis Pattern in SOA2008-04-17 IBM
  For SOA services to be successful and reusable, it is important that the data they expose is of acceptable quality for all the consumers. Exposing quality data is necessary in any SOA initiative. Whether it is application services being exposed or a simple generated data query service, the resulting data must be accurate and appropriate to the business context to be of any value. Data profiling and, in particular, quality analysis are traditional components of enterprise data architecture.
