Property spin:constructor

rdf:Property

Can be used to attach a "constructor" to a class. A constructor is a SPARQL CONSTRUCT query or INSERT/DELETE Update operation that can add initial values to the current instance. At execution time, the variable ?this is bound to the current instance. Tools can call constructors of a class and its superclasses when an instance of a class has been created. Constructors will also be used to initialize resources that have received a new rdf:type triple as a result of spin:rules firing.
