This is the Uno Wiki. Uno stands for Universal Network Objects.
Uno is the interface based component model of http://OpenOffice.org. Uno offers interoperability between programming languages, object models and hardware architectures, either in process or over process boundaries, as well as in the intranet or the Internet. Uno components may be implemented in and accessed from any programming language for which a Uno implementation (AKA language binding) and an appropriate bridge or adapter exists.
It is planned to move most content from the http://udk.openoffice.org pages into the Wiki. You are welcome to help. Probably most interesting for many people is, what we are currently doing in Uno, which you can find in the efforts area. One of the bigger things is the extension to Binary Unos threading-model.
The Uno Wiki organization is described in Uno/Meta/Organization.
