I could be wrong, the project might have changed hands for all I know,
but I think you're thinking of Jay Fields: http://blog.jayfields.com/

...and just to set the record straight, DM's validations started out
custom, implementing Martin Fowler's idea of Contextual Validations,
though to be fair, 90%+ of the syntax was borrowed from Rails. Then we
switched to Validatable, which seemed like a good idea at the time,
but required overwriting a good bit of the Validatable code. Now we've
gone back to the original DM validations and just filled in the areas
we didn't cover so well before.

Now I've got a little transcoding to do, and then it's all DM, all day
hopefully. ;-)

Oh yeah, Adam Keys is a great guy. Organizes a lot of Ruby related
events around Dallas. Spreads the knowledge. Brilliantly smart. OTOH
his love of Rails frustrates me to no end. :-D
