Yes, I'll be very happy to:)

I don't know in depth about the DotGNU project, so I don't know how much
my project will be useful for DotGNU, so let me describe what SandStorm is

On it's core, SandStorm defines a way to build lightweight "component"
system on top of XML-RPC.

A component is defined as a set of methods with common dotted prefix, so,
for example, if an XML-RPC server serving this methods:


It can be said it serves the component gnu.savannah.

SandStorm also defines a registry, and an XML-RPC API to the registry. so,
if in our case, the server sits on, it can notify the registry
it handles the gnu.savannah namespace:


A client that wishes to work with a component, calls


and he gets the location of the XML-RPC server. with a simple wrapper,
this can become trivial task.

There is also SIDL, Sandstorm Interface Definition language. there is a
parser for python, which can validate running components. example:

interface GnuSavannah
revision 0.1;
namespace gnu.savannah;
string[] getProjects();
struct getProject(string name);

Another part is a set of "bindings", to make accessing the registry
easier, currently done for PHP(using enhanced usefulinc code), Python
(using enhanced xmlrpclib code), Java (using enhanced helma), Ruby, and
semi-working Perl.

There is also a registry implementations in Java and Python, and a set of
useful example components. A cache API, RSS fetcher/parser, and user
authentication framework(all in python).

I started it in last march. I am a tech volenteer at indymedia israel and
global indymedia tech stuff. I wanted to rewrite active(indymedia's
engine), in a more modular and scaleable fashion, but it turned up to me
that the architecture is quite general-purpose:)

The rewrite of active(called active-xmlrpc) is quite functional. Part of
the components are in java, others in python. The front-end is currently
Zope, but i'm working on a Ruby frontend.

Well, that's all of now...
