What is Device Management Framework (DMF)?

DMF is a collection of source code libraries that extend the capabilities of GoAhead WebServer to provide the features commonly needed by embedded product developers.

Features:

Clean separation of server-side and client-side code. DMF builds on GoAhead WebServer's ASP-style programming environment by adding a consistent and uniform parameter access model. Embedded engineers don't need to know client-side technologies like HTML and JavaScript. Web designers can create rich user interfaces using traditional web development tools.
XML-RPC. The XML-RPC (Remote Procedure Calls) protocol is a simple, portable way to make remote procedure calls over HTTP. Programs written in Python, Perl, Java, C++, PHP and many other languages can connect to devices running DMF and access their functionality. XML-RPC is an ideal way to communicate between multiple devices and other applications. For example, a Java application that is used to control multiple DMF-enabled devices simultaneously. See www.xmlrpc.com for more information about the XML-RPC protocol.
Powerful, consistent parameter access model. Every device parameter has built-in data validation and parameter-level access control.
Rich error pages. Allows web designers to create server error pages that match the look and feel of the main interface.
Security & Authentication. User management and page-level access control available through Ejscript.
JavaScript libraries. Includes features such as dynamic page updating, table sorting, navigation functions, cookies, charts, and more.
Much more. New features are being added regularly.

XML-RPC Client for Macromedia Flash

An ActionScript library enables web designers to create rich, dynamic user interfaces using Macromedia development tools. Device parameter names can be mapped to variables inside Flash and get/set using XML-RPC.

Flash is an ideal technology for embedded devices. Flash movies are vector-based, making them smaller and faster than implementations using other plug-ins. Independent surveys show that over 98% of all web users have Flash installed, making it the most popular internet client available. Plus, Flash(tm) works consistently across multiple platforms, browsers, and even PDA's.

Platform Support

Device Management Framework and GoAhead WebServer are written in portable ANSI-C. Currently supported platforms include Embedded Linux (and Linux), eCOS, VxWorks, QNX, Lynx, Windows, (including Windows CE), and Mac OS X.

Additional contributed platforms are available. Normally the code can be ported in a few days, depending on the desired platform.

Memory footprint of a typical build is approximately 300K. A file system is optional.

Device Simulation on Windows

In addition, Device Management Framework and GoAhead WebServer run on Windows XP/2K/NT/9x and Mac OS X, providing a simulated environment for developing web code. The user interface and server-side scripts can be developed before (or in parallel with) the firmware and hardware.

GoAhead support partner

Art & Logic is GoAhead Software's support partner for GoAhead WebServer and manages the open source code base.
