Re: Another Poll of Ref Models

[Raffaele Fragapane <jaco(at)thejaco.com>]

Well, the subject is a bit hazy.

My comment on mixer inheritance and the positioning of data (which I 
think is handled smartly enough) goes for models in general.

Going by the assumption that we're fine with the discrepancy between 
facade and internal state (a hierarchy is presented when you really have 
parallel name spaces under the hood), I think the way sources and clips 
are positioned and used is logical, or at the very least convenient, as 
it sweeps off right away issues that require tricky dependancy tracking 
like multiple scopes, an override system etc.

I'm also fine with this being handled the same way for ref and local 
models, as it enforces consistancy, and helps with referencing (having 
something that can be safely isolated), having a different behaviour for 
the two referencing modes (scene embedded VS external) would cause no 
end of trouble, potential data corruption, and it would bring up even 
more issues with conversion, that would have to either be left to 
baffled users, or performed going by some heuristics that wouldn't 
probably be smart enough to handle every possible case.

The thread is about ref models and how reliable they are these days 
though, and going by that I think not everything is perfect yet, or at 
least not in the form I would like it to be.

If you can understand this email you win a teddy bear.
