[Opensim-dev] Presenting unga: UGAIM grid servers with PHP

Wed Apr 7 16:33:55 UTC 2010

Hi,

Which are the differences on the published public interfaces between
old UGAIM and ROBUST? Maybe I'm totally wrong but I can't see anyone:
both use http, both use xml-rpc/REST/DAV/whatever.

The way it does its job is irrelevant. ugaim and robust both are serving http.

If you need an asset the final request will be
"http://anyserver:anyport/asset/UUID".
If you need an inventory folder:
"http://anyserver:anyport/anydir/RequestFolder".
If you need whatever you need: "http://anyserver:anyport/anyserviceyouwant/"

Only older versions? Any version of opensimulator should be able to
connect. Maybe not all methods are implemented (in robust there were
dummy methods too) but it should work.

unga is not a CMS integration with anything. If I wanted that I will
use Drupal, Joomla, DotNetNuke, Sharepoint or a telnet window.

unga is a framework (over a mvc framework) programmed in php, capable
to run inside ANY web server (with all its advantages) and oriented to
working as support services for opensim. And it provides the same
services as UGAIM/ROBUST, a graphical console and a bunch of another
useful things.

I feel most comfortable using a well-tested web server (apache,
lighttpd, iis, nginx...) for serving http than having a .net program
using basic http libraries. I know how to improve the performance,
security or scalability on an Apache system, but I don't know if this
is possible with ugaim/robust. For me the decision was quite easy.

I don't intend to substitute anything, but I'm free to do the things
the way I like, and, if I don't like something, to throw it or change
it to suit my needs (this is the spirit of open source, isn't it?).
Maybe some people think like me, maybe others hate my ideas...

If I opened this project to everybody is for some kind of debt with
the open source community (some people call it foolishness) and with
the intention to enrich the opensimulator universe (as any other
project present in the "forge" does).

Anyway, unga started as a support service for MY projects, anyone is
free to use it or throw it. I will continue to developing and
improving the project until I get tired or while I need it.

So that is...
