Machine-readable cardinalities

Hi,

I'm writing a code generator that converts Schema.org's types to PHP
classes.

I'm looking for a machine-friendly way to extract cardinalities of
properties.

Actually I've started to parse rdf:comment with regex but this is not
practical. Does someone has a better idea?

A notation such as the one used in Good Relations would be pleasant:

10).

Thanks.
