This sounds interesting. Below are some resources.
Currently, Ptolemy has two unit systems in place, so
some of this data is available. See ptolemy.data.unit.
There is some work involving properties such as the
const-ness of a data port. See ptolemy.data.properties

The key to adding metadata is to do it in such a manner
that the token size is not increased substantially
and processing time does not take longer. Look at
the nil token work as a possible solution.
