| Introducing MicroXML, Part 1: Explore the basic principles of MicroXML
Parts of the XML community always grumble that XML is difficult to understand
and process. XML is fundamentally complex for various historical reasons, and people
proposed simplified versions for more than a decade. JSON and HTML5 threaten some of
the most basic XML tenets. MicroXML -- a simplification of XML that is compatible with
earlier versions -- emerged from discussions of these issues. MicroXML is now under
the guidance of a W3C community group, and several basic implementations are already
available for the draft specification. In this first article of a two-part series, learn from one of the MicroXML Community Group co-chairs about MicroXML and its technical differences from the XML 1.x core standards.

| Introducing MicroXML, Part 2: Process MicroXML with microxml-js
MicroXML is a simplification of XML that is compatible with earlier versions.
Part 1 of this two-article series covers the basic principles of MicroXML. MicroXML is
designed with a straightforward grammar that can be processed with many modern
general-purpose parsing tools. James Clark, who led the original push for MicroXML, is
among those thinkers who developed a parser for the community specification.
Learn how to use Clark's JavaScript MicroXML parser to experiment with the format.

| Creating a Drupal multisite installation
One important feature of the Drupal content management system
is that it enables you to run multiple websites from a single base
installation of the framework -- a feature called multisite
installations. Such installations are particularly useful to web
administrators who have to manage and maintain several sites on a long-term
basis, and the functionality simplifies the administration of multiple Drupal
installations located on the same server by making all of them run from a
single script. In this article, see how to install, configure, run,
and administer multisite Drupal.

| Test automation and continuous integration with STAF/STAX
Regression and incremental tests play an important role during the testing
of an application that might comprise hundreds or thousands of requirements. While the execution
of incremental tests can sometimes be run manually, regression tests require an automation
tool or framework. The support for multiple operating systems, architectures, and middleware
software, like application servers and databases, make the necessity of an automation framework
even more urgent. This article briefly introduces STAF/STAX test automation framework. It also
shows how you can use it to build a framework for the automation of tests and continuous

| Comment lines: Using an adapter service pattern to build a more flexible, low maintenance ESB
Integrating multiple systems in a point to point manner can be very time
consuming and expensive to maintain. One common approach to resolve this issue
is to introduce an Enterprise Service Bus (ESB), which replaces the point to
point approach with a single, centralized place to integrate systems, and does
so in a service-oriented manner. However, if done incorrectly, this can still
create maintenance headaches. Here is a look at a pattern that can “future
proof” your integration work, allowing for the upgrading or replacement of legacy systems without excessive additional integration work.

| Comment lines: Defeat image sprawl, once and for all
Virtualization and cloud computing make it very easy to create new
virtual images, but as image catalogs grow, finding and locating the right
images gets harder. New images are created because it is easier to create a
new image than it is to figure out what existing image might be reusable,
creating "image sprawl." Unless you address how to more effectively build and manage your virtual
images, you will not realize the full benefits of the cloud. Two new IBM
capabilities, the Virtual Image Library and the Image Construction and
Composition Tool, can help you quickly understand the content of your images
and build reusable, parameterized images.
