Ruby gem for OQGraph Engine

I've released a Ruby gem to allow the use of the OQGraph engine with Ruby on Rails' ActiveRecord class.

It can be found at http://github.com/stuart/acts_as_oqgraph

I hope someone finds it useful.

A demonstration Rails app using this will be completed soon.
I've had good results with a test set of 10000 nodes connected by ~50000 edges. Requests for shortest paths
are completing within 5 to 10ms.

I'm testing on larger datasets today, but it's taking quite some time to insert all the edges.

Cheers and thanks to the Open Query folk for all the work on the engine,
Stuart Coyle
