XForms: an Introduction

Steven Pemberton, CWI

XForms is a declarative language for applications, on the web and elsewhere.

Who uses it

It is a W3C standard, and in worldwide use, for instance by

And many others.

Experience

Experience has shown that it greatly simplifies making applications.

Example: A company that makes BIG machines.

The user interface is very demanding — traditionally needed 5 years, and 30 people. With XForms this became: 1 year, 10 people. Do the sums. Assume one person costs 100k a year: then this has gone from a 15M cost to a 1M cost. They have saved 14 million! (And 4 years)

Example: Insurance Industry

Manager: I want you to come back to me in 2 days with estimates of how long it will take your teams to make the application.

(Two days later)

Programming person: I'll need 30 days to work out how long it will take to program it.

XForms person: I've already programmed it!

Example: NHS

The British National Health Service started a project for a health records system.

One person then created a system using XForms.
