VectorWise is not open-source yet, but you can get involved today with the Ingres integration,
tools and the interface work with the Ingres community edition.
Some areas you can get involved in include Ingres community edition work, interfaces, administration tools, migration tools, documentation, test cases,
suggestions for future project work and many more!
You can learn more on the
Ingres VectorWise blog
and discuss the project in a dedicated section on the
Ingres community forums
