==Cardinality==

OPM knows cardinality constraining, meaning a way to indicate to what extent 2 objects can relate to each other. In OPM these constraints are called participation constraints.

Example: 1 man can marry 1 woman. The constraining makes this a 1 to 1 relation.

Constraining can be formulated like:

* 1 to 1 ('''Example: 1 man can marry 1 woman''')

* 1 to 1

* 1 to many

* 1 to fixed number
