In terms of graphing metadata, it generally makes sense to define the
graphs outside the scope of any individual model. And the approach I
have taken with my own little simulation tool is to allow graphing
and/or simulation metadata (RDF/XML) to be used directly as the
user-input. The metadata can then be queried to determine what models
need to be loaded and the simulations to be run.

Perhaps a similar approach could be used in PCEnv and users could be
allowed to load metadata directly in addition to straight CellML models.
And then it is this "independent" metadata that is being edited by the
user when they manipulate graphs in PCEnv.
