WURFL Tag-Library: a Compelling Demo
Imagine you are a network operator in GSM. Lots of cool phones
out there, but..Geee! there is not one like the other.
Yet you need to come up with a portal that makes sense to all of your users:
from those who surf wirelessly on their legacy 7110 bananas
to the proud owners of expensive MMS/J2ME/Built-in camera
technology jewels.
The solution to this problem is not simple. You can code several pages,
but the problem is that the features you support distribute randomly across
devices and there is no way you can keep up with more and more
different devices coming up each day.
The WURFL makes all this so much easier. With the WURFL you don't need to care
about those device capabilities any longer. You just need to focus on
the capability of the device when you build your application (as opposed to
caring about the device).
You can say things like "create this link if device supports MMS"
(as opposed to "create this link if device is Nokia 7650 or SonyEricsson T68i").
If you are not convinced, just think of what happens to users of a new MMS
phone when they hit your application.
The demo that follows shows a fictional operator
portal that gives each device a list of services tailored
for the capability of the phone.
You can also hit a live demo of the application at
