SOA Policy
Organizations use policy to guide decisions that are important to both the business and IT. Many times, policy is reactive, and created as a result of something negative happening. The SOA Policy Reference Architecture shows how the practitioner can be proactive with policy creation and maintenance, including the ability to manage and automate that policy. This paper and its more detailed attachment provides a framework for defining policy starting with business goals and objectives and then decomposing those into the business, architectural, and operational policies necessary to properly control the organization. An example of using the SOA Policy Reference Architecture to create the policy decomposition will be given to aid the reader in understanding the details.

OData
OData is a Web API for Data Access and manipulation. It is similar to a mini-ODBC or JDBC API but specifically intended for the Web. More precisely, OData allows clients to construct URIs that name an entity set, filter among the entities it contains, and traverse relationships to related entities and collections of entities. OData provides mechanisms for resources (also known as providers) to present descriptions of the data structures they expose and for clients (also known as consumers) to access and manipulate the exposed portions of the resources via the HTTP protocol. The OData Web API describes how requests from clients and results from the providers should be formatted. The OData specification documents have been submitted to OASIS (Organization for the Advancement of Structured Information Standards) in May 2012.

Linked Data standards
Linked Data and the Semantic Web have always been of interest to IBM Research but Linked Data has now become a central component of some of IBM's products strategy. The Rational group in IBM has for several years been employing a read/write usage of Linked Data as an architectural style for integrating a suite of applications, and we have shipped commercial products using this technology. The applications we have integrated in IBM are primarily in the domains of Application Lifecycle Management (ALM) and Integration System Management (ISM), but we believe that using read/write Linked Data as an application integration technology could be broadly relevant and applicable within the IT industry.

USB-Like Universal Ports Type for Enterprise Service Bus, Part 3: Benefits of Universal Ports
In the first installment, part1 of this series, you learned about the basic functionalities of the currently available Enterprise Service Buses (ESBs). In part 1, you also learned about some of the difficulties in the use of the currently available ESBs. In the second installment, Part 2 of this series, you learned about the new concept of the Universal Ports type for ESB and how to implement Universal Ports. Universal Ports provide solution to the many of the problems that the current users of the ESBs experience. A Universal Port works analogous to the USB port of a computer, which is to connect devices of varied kind to connect to the computer. In a similar manner a Universal Port can be used to connect any application to the ESB and, indirectly, to the other applications. These applications may employ disparate forms of services to expose some or all of their functionality and still use a single port type. In this installment, part 3 of this series you will learn about the many benefits of Universal Ports.

Exploring the Vector behavior of relationships in common information model (CIM) based service-oriented architecture (SOA) environments
In the process of creating SOA based services from common information model, we know that there is a need to extend CIM due to its abstract nature. An important aspect to understand is that the driving context of the constellation of CIM objects pertaining to an SOA based service is its "Business intention". This article will explore such a characteristic of the relationships of CIM objects in SOA based implementations.

Integrate IBM FileNet P8 BPM with IBM WebSphere ILOG JRules using Web services
The competitive nature of today's business demands that an organization's business processes be highly dynamic. A business must accommodate and manage fast-changing business rules associated with business processes. A business rules management system (BRMS) enables you to extract business rules and decisions from business processes and manage them independently, thereby allowing the processes to be streamlined. This article describes how to integrate IBM(R) WebSphere(R) ILOG(R) JRules, an industry-leading BRMS, with IBM FileNet(R) P8 BPM, a comprehensive business process management system (BPMS). [The November 2010 update includes the following changes: the term expert system was changed to decision service; business rules conditional checking 1 equals 1 was removed; the PI prefix to verbalization was removed; the rules are better organized in in the rule packages; and the rule flow was updated based on the new package design. --Ed]

Using CICS with DB2 pureXML, Part 2: Perform advanced XML storage and retrieval through CICS Web services
This article is the second part of a series of articles. The first article focused on augmenting CICS(R) Web services with two general purpose routines (pipeline handlers) that support two scenarios to store and retrieve XML in DB2(R) pureXML. This second part introduces two more scenarios: a service request scenario and a service response scenario. The service request scenario shows how a custom pipeline handler can be introduced to further enhance CICS Web services to store XML data in relational form or in XML form after extracting the XML that represents the business data from the SOAP message. The service response scenario shows how a custom pipeline handler can be introduced to publish relational data as XML, and how XML data can be modified directly through SQL before returning the data in a service response. This article also illustrates how stored XML data can be accessed as relational data through a view for easy placement in a CICS COMMAREA or container. Some sample COBOL source code is included in the Downloads section.

Converting COM request to web service request
Since its introduction, web service has become a standard mechanism for integration between applications. However, there are many applications written in languages that do not provide a strong support for web service - for example Visual C++ V6.0 or Visual Basic V6.0. One approach to enable these applications is to have an adaptor that can convert a request into a web service call. This tutorial describes how to develop this adaptor implemented as a DCOM server using C#. It basically receives a COM request and forward the request to a web service endpoint. It also provides steps on how to make a COM request in C++ and shows steps on how to implement a Java web service. In short, it demonstrates how web service interoperability on the .NET and JEE platform can be achieved. C# code is developed using Microsoft Visual Studio, while the web services is developed using Rational Application Developer V7.5 and deployed on the WebSphere Application Server V7.0 test environment.

Selection criteria for packaged applications in service-oriented architecture environments
Selecting package applications is not just a matter of validating the functional match. There are important non-functional forces to conquer in order to meet the business ambition, e.g. business agility and time-to-market of the solution. However, the needs in the non-functional space are often hard to articulate. This article provides for a thinking framework to devise the criteria for package selection covering the non-functional business need as well.

Shades of common information model in SOA-based integration environments
SOA (service-oriented architecture) based architectural styles gets complex when combined with Common information model (CIM). This is because in reality the designer needs to extend the CIM for various reasons spanning the spectrum of including additional data elements for integration reasons to including elements required for carrying out business logics by the Service component. When the impact of such extensions on the core CIM is understood, it becomes easy to manage. Aspects related to the core CIM, extended CIM are discussed in this paper. In this article we explore the characteristics of each layer and the significance of maintaining them separately.
