Index of XML standards
The world of XML is vast and growing, with a huge variety of standards and technologies that interact in complex ways. It can be difficult for beginners to navigate the most important aspects of XML, and for users to keep track of new entries and changes in the space. XML is a basic syntax upon which you develop local and global vocabularies. This index provides a detailed cross-reference of many XML standards, including links to additional coverage for each.

Integration between XML Forms Generator and Data Studio, Part 2: DB2 pureXML support in XFG
The pureXML feature of IBM DB2 9 has revolutionized support for
XML data -- handling XML as a new data type that is stored in a natural hierarchy -- different
from relational data. IBM Data Studio can create Data Web Services with multiple pureXML
parameters to manipulate pureXML instances in the database. With the pureXML support in XML
Forms Generator (XFG), you can visualize pureXML into XHTML/XForm for user to interact. Also
XFG can retrieve the registered related XML Schemas of pureXML instances and generate type
information, validation constraints into the target pureXML XHTML/XForm. So pureXML support
in XFG makes it easy to build forms interfaces for XML instances stored in pureXML.

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.

Use XForms and Ajax to create an autosuggest form field
Web application development has been revolutionized by Ajax. What was once a new and flashy technology is now becoming ubiquitous. End users are coming to expect that certain interactions with a Web application will be done "with no refresh," in other words, using Ajax. The ubiquity of Ajax for users has not yet translated to client-side technologies. There are many Ajax frameworks out there that make it simpler to use Ajax, hiding some of the cross-browser issues, but building an Ajax-enabled Web application is still a non-trivial task, to say the least. XForms is a standardized technology that offers many benefits that are complimentary to Ajax. In this article you will see some of the benefits of using Ajax and XForms together by implementing an autosuggest field.

Generate Web services for DB2 9 pureXML
Web services are important building blocks to achieve service-oriented architecture. As more and more applications move towards a Service Oriented Architecture, often times there is a need to expose application functionality as Web services. The purpose of this article is to show how you can easily generate Web services using a simple Java class to insert and retrieve XML data, into, and from DB2 9 using the pureXML feature. Once the Web services are generated and deployed on WebSphere Application Server, you can test it using either the built in Web services Explorer of Rational Application Developer (RAD) or XForms as a Web services client. The same services can be used by any Web services client that can make SOAP over HTTP Web service calls.

Report Data Analyzer: Interpret EWLM performance data
As a workload manager (and not a capacity planning tool), the IBM Enterprise
Workload Manager focuses on real-time data and, thus, only retains performance data
covering the past 24 hours. There was a customer requirement, however, to have this data
available for later analysis. And so, the Data Hardening plug-in was added. This plug-in
allows on-the-fly dumping of performance data onto the file system. But, the
dumped data can't be directly exploited: Enter EWLM Report Data Analyzer.

One of the slickest application genres are those that update data as you type. XForms does this with finesse! Controls have the ability to send events after each keystroke entered within them using the incremental attribute. That way controls that need to change their data based on the data of a control that's changing incrementally can also update their data incrementally, effectively keeping what's viewed "on screen" in sync across the board. This tip shows you how to make the most of the incremental feature with sample XForms code.

XForms tip: Dynamically create controls with the repeat, select1, and itemset elements
Forms can have lists of data, which are difficult to display using regular HTML forms. The select1 and itemset elements have a lot of flexibility and are very similar to the select or option tags in HTML. The repeat element really shows its power here in that you can have a list of lists of data, and so on. You'll see how slick it is to populate the data used by the forms using XML. Once you use these XForms controls and populate them using XML, you'll never want to go back to using HTML ever again!

XForms tip: Using calculations
Part of the allure of XForms is the fact that it provides more of an opportunity to provide interactivity than regular HTML forms, or at least it provides an opportunity to provide that interactivity with much less hassle. One function that's fairly common in Web forms is the ability to perform a calculation based on data supplied by the user. In a traditional HTML form, this means creating a JavaScript script and checking for specific actions such as the user clicking on a button or leaving a particular field. Any of these actions can be prone to error based on different browser versions or rendering of the form in a nontraditional browser. Fortunately, XForms solves this problem by providing a standard way to include calculations in the functionality of your form.

XForms and P3P
Because of the rise of identity theft, online privacy has become a big issue. Many sites have privacy policies in place, but who has time to read and decipher each one as you do your daily surfing? Fortunately, there is an easier way. The Platform for Privacy Preferences, or P3P, provides a standard way for sites to define the information they collect, which makes it possible for tools to do the deciphering for you. Because XForms is so often used to collect personal information, it is crucial that it be included in this process.

Dynamic XForms submissions
XForms is an ideal open standards technology for collecting and submitting
data from a wide variety of Web-capable platforms. Creating a single input form for collecting data from many sources is common. However, each location filling out the form may have its own site unique submission requirements such as submitting to multiple targets that are not known to the form author. Mutliple submission targets include local save locations, or submitting to a write-only "vault" for auditing or logging, or any other site-specific submission targets. Using JavaScript to edit the DOM with XForms allows a single form to accommodate multiple, site-unique submission requirements.

XForms tip: Accepting XForms data in PHP
In some ways, an XForms form is just like an HTML form; with the proper encoding, the server-side script receiving the data won't even know the difference.
