The Openschemas' profiles define a community agreed layer over the Schema.org model providing additional constraints. These constraints capture (i) the information properties agreed by the community which are minimum (M), recommended (R), or optional (O), (ii) the cardinality of the property, i.e. whether it is expected to occur once or many times, and (iii) associated controlled vocabulary terms drawn from existing ontologies.
