  • [No name]
    • This association type connects fields with the topic types that can have the fields. Note that for association types we must also specify the role type, since the association type is not sufficient in itself. Usage: <pre> has-field(person : topic-type, email : field) has-field(person : topic-type, born-in : field, person : role-type) </pre>
