Argument
Provides metadata about an argument of a SPIN Function or Template. Arguments wrap a given rdf:Property (predicate) and specify its value type and whether the argument is optional. When used as spin:constraint, the body of this template will verify that a non-optional value exists and that it has the specified value type. Arguments that have been declared spl:optional true become optional if the type of ?this is spl:UnionTemplate.

Attribute
Defines an "attribute" of a class. Attribute definitions bundle common modeling patterns known from object-oriented languages like UML. Each attribute can have min and max cardinality, a value type and a default value. The attribute links a class with one RDF property. This template should be used as spin:constraints on a class to make sure that classes meet the expected cardinalities and valueType constraints. If a model wants to use spl:defaultValue, then it should instantiate the spl:ConstructDefaultValues as a spin:constructor at some root class, such as rdfs:Resource.
