Search Results for "XForms"
Forms are a part of our lives. They are used day by day in the ordinary life, but online they have a special place. They are the primary way of collecting information, being used for search engines, polls, surveys, electronic commerce, and even on-line applications. Every type of user-interaction on-line is done through web-forms of some sort. However, this technology is already showing it's age. Being created 5 years before XML, it has limitations, that make developer's and user's lives harder. Among them are:
As forms are older than XML,
This short description is about the work of XForms. Before talking about XForms it's important to understand the concept of forms. Forms are to collect the data so we should not get surprised if we say XForms is basically depending on instance data. Instance data are these data which are based on XML. The data are defined in the terms of XPath's internal tree illustration and dispensation of XML.
It may look odd at first to relate XPath with XForms. However, XPath is the well-known as the ordinary layer between XSLT and XPointer. Since XForms
Think about how many times a day you use forms, electronic or otherwise. On the Web, forms have become commonplace for search engines, polls, surveys, electronic commerce, and even on-line applications. Nearly all user interaction on the Web is through forms of some sort. This ubiquitous technology, however, is showing its age. It predates XML by half a decade, which is a contributing factor to some of its limitations:
Poor integration with XML
Limited features make even common tasks dependent on scripting
Device dependent, running well only on
Uche Ogbuji wrote a good article on XML.com here is a summary: "I’m still getting my Weblogger profile here updated, but this year I transitioned from one company I co-founded to another. Zepheira provides data architecture solutions, with a focus on semantic technology. I was early on the Semantic Web bandwagon, and I almost fell off at one point because I felt the useful, modest ideas at the core had been overrun by an academic brand of technological megalomania. This year I felt the timing was right to not only renew my interest in the technology,
Forms are for collecting data, so it's not surprising that the most important concept in XForms is "instance data", an internal representation of the data mapped to the familiar "form controls". Instance data is based on XML and defined in terms of XPath's internal tree representation and processing of XML.
It might seem strange at first to associate XPath and XForms. XPath is best known as the common layer between XSLT and XPointer, not as a foundation for web forms. As XForms evolved, however, it became apparent that forms needed greater structure
Unlike the original HTML forms, the creators of XForms have used a Model-View-Controller approach. The "model" consists of one or more XForms models describing form data, constraints upon that data, and submissions. The "view" describes what controls appear in the form, how they are grouped together, and what data they are bound to. CSS can be used to describe a form's appearance.
An XForms document can be as simple as an HTML form (by only specifying the submission element in the model section, and placing the controls in the body), but XForms
XForms is the next generation of HTML forms.
XForms uses XML to create input forms on the Web.
What You Should Already Know
Before you continue you should have a basic understanding of the following:
* HTML

What Is XForms?
* XForms is the next generation of HTML forms
* XForms is richer and more flexible than HTML forms
* XForms will be the forms standard in XHTML 2.0
* XForms is platform and device independent

The Forms working group is chartered by the W3C to develop the next generation of forms technology for the world wide web. The mission is to address the patterns of intricacy, dynamism, multi-modality, and device independence that have become prevalent in Web Forms Applications around the world. The technical reports of this working group have the root name XForms due to the use of XML to express the vocabulary of the forms technology developed by the working group.
The Forms Working Group is comprised of W3C members and invited experts. The Working
XForms is a relatively recent standard from the W3C, designed to allow us to create sophisticated user interfaces using mark-up. This means that defining a user interface is much the same as using HTML, except that XForms has been designed from the ground up to cope with many of the things that we usually have to dive into script to do.
And XForms doesn't just make it easy to replace script in our applications, it also provides us with the means to manipulate and validate XML; unlike most languages that you might have used, XForms brings XML right
If you browse the Web at all, you probably use forms more often than you realize. Nearly all on-line interaction (as opposed to static text delivery) takes place through some kind of form. To enhance the use of forms on the Web, the World Wide Web Consortium (W3C) sponsored the development of XForms.
Instead of further altering the existing forms language that is part of HTML, the W3C membership agreed that a new approach was necessary. Several years later, this has become XForms 1.0, an official Recommendation of the W3C.
Like XHTML, SVG, and
HTML is probably the world's most important data format, and so changes come very slowly. But the World Wide Web Consortium's HTML Working Group has big plans for HTML.
The current HTML standard is actually now XHTML 1.0 Second Edition, which is a set of minor changes to HTML to turn it into valid XML while still allowing current Web browsers to handle it.
The big news is XHTML 2.0, a from-the-ground-up rethinking of HTML that keeps its strengths while ditching some long-standing stupidities or legacy items. It will not be fully backward-compatible
XForms Conversion Overview
The XForms Converter utility was developed to provide the ability to perform the conversion of XForms documents into Adobe’s XML Forms Architecture (XFA) documents. The resulting files are XDP documents that can be used in Adobe’s LiveCycle Designer application. The utility can be invoked via the console or a Java Swing client. Further details on how it can be invoked are provided in the Operation section of this document. This is an alpha version of the utility.
About XForms

This is a continuation of the post Of state handling, part I published last month.
In Orbeon Forms, the XForms engine is split between the web browser (client) and the server. Client and server communicate with each other through Ajax. The client is relatively simple and written entirely in JavaScript. The server is written in Java, is smarter and does most of the XForms processing. While the client keeps a few data structures in JavaScript, in addition to the HTML forms and HTML DOM which themselves contain some information, the server represents
Using the experimental Mozilla XForms extension, you can process XForms in your browser today. While not yet deployed widely enough for use on the public Internet, XForms may be suitable for some intranet applications. This article demonstrates basic XForms processing as currently supported by Firefox and the Mozilla XForms plug-in.
XForms makes development of Web-deployed applications faster and easier. XForms' clean architecture makes applications more robust, more scalable, faster, and more secure. Except for one little detail, developing with
The XForms model defines a template for the data to be collected in a form.
The XForms Framework
The purpose of an HTML form is to collect data. XForms has the same purpose.
With XForms, input data is described in two different parts:
* The XForm model (to describe the data and the logic)
* The XForm user interface (to display and input the data)
The XForms model defines what the form is, what data it contains, and what it should do.
The XForms user interface defines the input fields and how they should be displayed.
The XForms

XForms
Yesterday I played with XForms. I have not yet taken the time to read the specification. Instead, I used some examples I found at Bugzilla and the Mozilla XForms project site. Not really the correct way to learn new things, especially since the implementation has some bugs and I might end up thinking such a bug is actually the correct behavior. (Anyone seeing the similarities with the CSS implementation in Internet Explorer? Take the box model for a good example.)
Although I still think XForms is rather complex and could have used some
XForms is an XML format for the specification of a data processing model for XML data and user interface(s) for the XML data, such as web forms. XForms was designed to be the next generation of HTML / XHTML forms, but is generic enough that it can also be used in a standalone manner or with presentation languages other than XHTML to describe a user interface and a set of common data manipulation tasks.
XForms, much like XHTML 2.0 which is currently under development as of November 2006 and within which XForms will be embedded, differs from previous
