ODF is the vendor-neutral and application-neutral open International Standard for office documents. The ODF Toolkit Union is an open source community that develops and hosts tools that make it easier to work with ODF documents.

Projects that are available with the ODF Toolkit Union range from small tools that simplify using ODF in the software development process and an ODF validation tool up to complete Java and .NET libraries that can be used within other projects. And this is just the start. Developers are invited to host their open source ODF libraries and tools within the ODF Toolkit Union, to join the existing projects, and to collaborate with other ODF developers in the ODF Toolkit Union.
