Microsoft Mobile Device Browse File and dotMobi DeviceAtlas

I got a open source project which I think it is supporting by Microsoft and / or dotMobi. the project name is Mobile Device Browse File or Mobile Browser Definition File. Actually I knew dotMobi Inc. has a similar project named dotMobiā„¢ DeviceAtlasā„¢, I don’t know what the differences between these 2 projects, or they are the same ? I am not sure, but I really see there are some differences from their introductions:

1: Mobile Device Browse File:

Project Description
The Mobile Browser Definition File contains definitions for individual mobile devices and browsers. At run time, ASP.NET uses the information in the request header to determine what type of device/browser has made the request.

This project provides a data file that when used with ASP.NET will detect the incoming mobile device and present you as the web developer with a set of 67 capabilities or properties describing the requesting device. These capabilities range from screen size to cookie support and provide all the information you need to adaptively render content for mobile phones and devices.

What is the Mobile Device Browser Definition File?
The Mobile Device Browser Definition File contains capability definitions for individual mobile devices and browsers. At run time, ASP.NET uses this .browser file, along with the information in the HTTP request header, to determine what type of device/browser has made the request and what the capabilities of that device are. This information is exposed to the developer through the Request.Browser property and allows them to tailor the presentation of their web page to suit the capabilities of the target device.

2: DotMobi DeviceAtlas

DeviceAtlas is the world’s most comprehensive database of mobile device information and features…
– Multi-sourced data, for maximum reliability and scope.
– Frequently Updated.
– Market leading performance, with small footprint.
– Transparent, Supported, and Future Proof.

DeviceAtlas for Microsoft ASP.NET BETA consists of a module which will integrate seamlessly with ASP.NET 2.0 and above – requiring just a single configuration line and installation of a DLL. Once installed, the module allows developers to use existing mobile controls with the benefit of new fresh data from DeviceAtlas which currently includes data on over 4,500 mobile devices.

I will get more info about them some day.
