Virtual Panel: Specification by Example, Executable Specifications, Scenarios and Feature Injection
In the last couple of years terms like Specification by Example, Executable Specifications and Feature Injection have showed up quite frequently in the community, often in relation to Behaviour Driven Development (BDD) or tools like Cucumber or SpecFlow. InfoQ have talked to some of the leading experts in this domain about what these practices are and how they relate to BDD.

Resource-Oriented Architecture: Information, Not Containers
The Web is known primarily as a Web of Documents because that has been our main experience with it, but we should not ignore the idea of documents as a data source. New technologies are emerging to make it easier to encode extractable content on the Web. This article focuses on how producers can increase the machine-processability of the documents they produce.

Wonderland Of SOA Governance
Michael Poulin elaborates on the differences between of governance and management and tries to explore the 'wonderland' of governance in a service-oriented environment. He defines SOA Governance, explores the relationship between governance and enterprise architecture, and discusses accountability and ownership of governance efforts, and how practitioners can instrument SOA governance.

Encrypting the Internet
The authors, from Intel, offer a three pronged approach to providing secure transmission of high volume HTML traffic: new CPU instructions to accelerate cryptographic operations; a novel implementation of the RSA algorithm to accelerate public key encryption; and using SMT to balance web server and cryptographic operations. Their approach, they claim, leads to significant cost savings.

RESTful HTTP in practice
Gregor Roth overviews the basics of RESTful HTTP and discusses typical issues that developers face when they design RESTful HTTP applications, showing how to apply the REST architecture style in practice. Gregor describes commonly used approaches to name URIs, discusses how to interact with resources through the Uniform interface, when to use PUT or POST and how to support non-CRUD operations.

Why Do We Need Distributed OSGi?
Recently, an early release draft of a Distributed OSGi requirements and design document has been published, long with a reference implementation as part of Apache CXF. In a new article, Eric Newcomer writes about the current status of distributed OSGi and explains the reasons for standardizing it in the first place, and its significance to the OSGi specification and community.

SOA Governance: An Enterprise View
SOA architect Michael Poulin explains the necessity for SOA governance to ensure an SOA initiative's success, and explains the role the OASIS SOA Reference Model and the accompanying SOA Reference Architecture assign to SOA Governance. Michael observes SOA governance specifics from the enterprise perspective and illustrates them with several examples of SOA Governance policies.

Simple JAVA and .NET SOA interoperability
.NET and Java interop can be made really simple using a REST documentcentric approach. This article compares a REST and SOAP approach to interop as well as the advantages of using HTTP POST vs. GET for REST invocations.

A History of Extended Transactions
ACID transactions don't work for long-lived use cases. This article documents historic approaches taken in the CORBA and J2EE communities toward extended transactions, how SOA is a more natural fit, and why WS-TX & WS-CAF may finally hold the answer.
