[one-users] Development technologies

[Javier Fontan]

Hello,

Here are the technologies being used for the project:

 * Build system: scons
 * Core: C++
 * Data base library: sqlite
 * Client comunication protocol: xmlrpc (the library used in the core
to provide this is http://xmlrpc-c.sourceforge.net/ and uses the
embedded abyss server)
 * Command line interface: ruby, the communication with server is done
with standard xmlrpc libraries that come with ruby distribution
 * Drivers: Most of the drivers are programmed in ruby. The
communication core<->drivers protocol is a custom text message
protocol and uses unix pipes between core and driver processes.
 * Information manager driver executes probes in the remote nodes,
this probes can be executables or scripts in any language or format
that the remote nodes support.
 * Transfer manager uses shell scripts to describe each of the
commands available to perform to images. They can also be programmed
in any other language.
 * Communication with execution nodes is done through ssh
 * VMWare drivers are programmed in java.

Tell me if you need more information or some clarifications.

Bye
