What is that ?

Input ports do not have a default value in Rock (and IMO should not have
...)

Even though I have a strong dislike with the idea (and that Rock's
guidelines state that the scale should be "1" w.r.t. the SI unit ...), I
have to admit that the Time class is already breaking that rule :(
Now, what I *am* wondering is: this is a "datatype" metadata, not a
property/port/... (e.g. the scale applies on the data, not on the port).
Shouldn't we have a separate metadata associated with the port/property
type (which would be merged with typelib's metadata information for the
type) ? Or how could we separate the port/property metadata from the
port/property's type metadata ?

Physical quantity: (length, angle, speed, rotational_speed, torque, ...)
