http://www.soamag.com The SOA Magazine is a monthly online publication provided by SOA Systems Inc. and Prentice Hall/PearsonPTR and is officially associated with the "Prentice Hall Service-Oriented Computing Series from Thomas Erl." SOA en-us Copyright 2006-2007, SOA Systems Inc. http://www.soamag.com/I4/0207-1.asp Fundamental to any SOA delivery project is the definition of services. More specifically, the ability to define what constitutes a service and how logic should be partitioned and represented across a collection of services. The ambitious goal of SOA to achieve unity between business and technology domains further makes service definition a critical step along a typical SOA roadmap. This is the second article in a series dedicated to exploring the functional side of SOA. It explores several ways to properly describe a service in a stage called "service elicitation," essentially the process of extracting services from business knowledge.

SOA http://www.soamag.com/contributors/bio-cthilloy.asp#When:29.01.07 http://www.soamag.com/I1/0906-1.asp This article is the first in a series exploring the various technologies and options available to an enterprise when establishing a service-oriented architecture (SOA) roadmap. It introduces the notion of an SOA infrastructure and enriches it with the models and frameworks currently available to SOA implementers. By describing architectural components and frameworks common to SOA, it defines the baseline for the service-oriented enterprise. Subsequent articles will further explore a possible methodology for SOA governance based on the formal description of the purpose of each service. This methodology provides diagrams and template examples of inputs and outputs on the decision paths needed for SOA adoption and roadmaps. (First published in The SOA Magazine Issue I, Sep/Oct 2006.)
