## *it* **a** *something*
|
|
|
|
|
|
|
|
|
|
*it* is **a** *something*
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Example:
|
|
|
|
|
```ttl
|
|
|
|
|
as:id a owl:DatatypeProperty ,
|
|
|
|
|
owl:FunctionalProperty,
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Maps to
|
|
|
|
|
```clojure
|
|
|
|
|
(s/def ::DatatypeProperty any?)
|
|
|
|
|
(s/def ::FunctionalProperty any?)
|
|
|
|
|
|
|
|
|
|
(s/def ::id
|
|
|
|
|
(s/and
|
|
|
|
|
::DeprecatedProperty
|
|
|
|
|
::FunctionalProperty))

Der token `a` in einer ttl Definition entspricht dem RDF-Prädikat `rdf:type`. Siehe:

Das bedeutet für das Tripel: `(R, rdf:type, C) => C instanceof rdfs:Class & R instanceof C`

### range (https://www.w3.org/TR/rdf12-schema/#ch_range)
|
|
|
|
|
|
|
|
|
|
"P rdfs:range C" indicates that:
|
|
|
|
|
1. P is an instance of the class rdf:Property
|
|
|
|
|
2. C is an instance of the class rdfs:Class
|
|
|
|
|
3. all the resources denoted by the objects of triples whose predicate is P are instances of the class C.
|
|
|
|
|
=>Bedeutet(?): Es gilt: Tupel = (Subjekt, Prädikat, Objekt):
|
|
|
|
|
=> Wenn (P, rdfs:range, C) & (S, P, C2) => C2 is instance of C
