two remarks: - what is the level of reification because we reify a lot and it can be discarded. - did you check the orion model because with orion you only represent the delta and this is a big difference. Stef

We are actually measuring the dependencies a method has. We therefore need invocations, access to attributes, ... Close to the maximum level of import then.

We haven't checked. Do you know whether Orion is integrated with Hismo? Can hismo be transparently used with Orion?

I do not know how work Hismo, but Orion work like a Famix model, if it can help you :)

Hismo provides many facilities to query the history, which is pretty cool We should indeed have a look at Orion. We will

Not that I know but orion is the way to go if you want to have a lot of data.
