OpenBayes was an earlier attempt to port BNT to python. It uses similar
network representation.

Given the conversations subsequent to this post re. establishing that Kevin Murphy has given the go ahead re. porting and relicensing his Bayes Net matlab toolbox for integration into scipy, it sounds like one of the first orders of business for those who signed up for this project might be to try to establish whether the Openbayes project, or minor modifications/extensions, could provide a useful framework for the port. I'll continue to look at both but my understanding at this point is that the matlab toolbox currently has significantly more functionality than the Openbayes project. Looking at Kevin Murphy's description of his toolbox it seems he took a broader approach than some Bayes net packages re. general approaches to estimation in graphical models (which was attractive to me) and that might entail a different approach to the structure of the package than the author of Openbayes took (but this is just speculation at this point - I
