XML Schema 1.1, Part 3: An introduction to XML Schema 1.1
A frequent goal of schema authors is to build schemas for extensibility, where wildcards play a key role in providing extensibility points. New wildcard features introduced in XML Schema 1.1 make it easier for schema authors to write extensible schemas that can tolerate changes in the future. In this third of a six part series of articles, authors Neil Delima, Sandy Gao, Michael Glavassevich, and Khaled Noaman take an in depth look at versioning features introduced by XML Schema 1.1, specifically the new powerful wildcard mechanisms and open content.

Meet CAM: A new XML validation technology
XML documents are frequently validated against either a DTD (less likely) or an XML schema (more likely). Recently, a new technology called Content Assembly Mechanism (CAM) has emerged. It is endorsed by the Organization for the Advancement of Structured Information Standards (OASIS). CAM represents a step up from XML schema because it provides even more flexibility in defining both the semantics of an XML document and the business rules associated with the actual data content. Take a broad overview of CAM, including its benefits over the alternatives, in this article.

Enforce basic document structure with XML constraint checking
The ability to specify, check and act upon constraints is vital to
ensuring the overall quality of healthcare information. The Health Level 7
(HL7) Clinical Document Architecture (CDA), described through XML Schema,
allows the specification of constraints through HL7 Templates, which can be
implemented in Schematron. Schematron can be applied through XSLT. This article illustrates software and
hardware solutions for constraint checking in the HL7 CDA. The two
solutions are demonstrated in an SOA that
includes both successful and failing XML Schema and Schematron constraint
checks. The article evaluates the application of constraints in the HL7 CDA
and identifies some categories of constraints that require further investigation.
The outcome of this evaluation shows that the ability to specify, check, and act
upon constraints through Schematron complements XML Schema processing. The two
constraint approaches are very useful and practical, and should therefore be
pursued further.

Explore multithreaded programming in XUL
As you create cross-platform desktop applications using XUL, you also can
enhance your skills with JavaScript, CSS, and even HTML. XUL's cross-platform
capabilities are not a collection of least common denominator features. Instead,
XUL gives you the kind of power that you might expect from a desktop application
toolkit, including access to native threads. You can even access native threads
directly from JavaScript, writing code that executes in parallel. In this article,
you will examine the multithreading capabilities of XUL, and create an application
that uses multiple threads to retrieve data. You will take a classic IO-bound
application, one that accesses multiple remote data sources over the Internet, and
speed it up through multiple threads in XUL. The application will allow users to
view and compare anonymous results of three popular search engines: Google,
Yahoo, and Bing from Microsoft(R).

Creating an Atom feed in PHP
Atom is an Extensible Markup Language (XML) specification that identifies information contained in a Web site. Using Atom, Web developers produce feeds that enable other Web developers (or consumers who use feed readers) to quickly locate and view information of interest on a remote site. Think of it as a Web site's index, available to anyone who wants it. Using PHP, a popular language of choice for most host providers, a Web developer can easily produce an Atom feed that can then be made available to the various feed readers and other Web developers. The ultimate result is a state-of-the-art information solution that enables the Web content to reach a much wider audience.

15 best practices for pureXML performance in DB2
DB2 9 introduces pureXML
support, which means that XML data is stored and queried in its inherent hierarchical format.
To query XML data, DB2 offers two languages, SQL/XML and XQuery. Additionally,
DB2 9 has sophisticated XML indexing capabilities and support for XML Schema
validation. While most existing performance guidelines for DB2 also apply to
XML data, this article provides additional XML-specific performance tips. This article has been updated for DB2 9.5. [2009 May 26: Corrected code in Listings 12 and 13.--Ed.]

Using DB2 XQuery to extract data mining results stored as PMML
Data mining is the process of finding rules and patterns in structured
data. DB2(R) data mining uses Intelligent Miner, which is part of
InfoSphere(R)
Warehouse. Intelligent Miner(R) stores those results in Predictive Model
Markup Language (PMML) format, which is based on XML.
Since the launch of DB2
9, information stored in XML can be processed efficiently using XQuery. Find
out how easily you can use DB2 XQuery to create your own access methods based on your data

Application logging using solidDB, WebSphere Message Broker, and DB2
pureXML
Because of its flexibility and its presence in many application
environments, XML is becoming the preferred log format. In this article,
you'll learn how to easily set up an application logging environment by
bringing the XML features of WebSphere and DB2 together. We first introduce a
simple application logging scenario, then show how to use solidDB for caching
and decoupling the application from the logging infrastructure. WebSphere
Message Queue and WebSphere Message Broker will be used to reliably move the
log messages from the application to DB2, where they can be stored and queried
using the pureXML functionality. To normalize different message formats,
WebSphere Message Broker will also be used to transform log files to other XML
formats prior to storing them into DB2.

Integration between XML Forms Generator and Data Studio, Part 1: Get started with the integration by creating an application
The XML Forms Generator (XFG) provides a jump-start for form development. It can
quickly and automatically produce valid and functional forms containing XForms markup
embedded within an XHTML document. The input to form generation can be an XML data
instance with or without a backing XML Schema, or a WSDL document. Data Web Services,
which is based on SQL scripts and Store Procedures, is a database related application
of traditional Web Services. IBM Data Studio is a client tool for generating Data Web Services visually with the help of direct connection to database.
The integration between XFG and Data Studio can enable to generate XForms/XHTMLs from Data
Web Services generated by Data Studio. This integration provides advantages such as joining the development of UI pages and Data access seamlessly, reducing the workload of UI development from Data Web Services, visualizing the pureXML UI development with full-support of validation, etc.

Create a framework to support XSLT transformation pipelines
Explore the creation of a framework, called Butterfly, that runs in PHP 5 and
facilitates the applications of chains of XSLT stylesheets to XML source documents.
This provides transparent caching of the transformed results. Inspired by the Java(TM)-based Apache Cocoon project, so named because it houses and manages the transformation of data from one form to another (turning caterpillars into butterflies), this much lighter-weight framework is named Butterfly. With the Butterfly framework, you can set up an XML configuration file to define chains of stylesheet transformations, and then instantiate Butterfly objects that can each produce the result of an XSLT transformation chain. This article will also look at the nature of framework design in general as it sketches out this framework in particular.
