object/nightwatch/3 matches the site
The Night Watch has an external URI that also identifies the same physical object in wikidata:
C#
public static HumanMadeObject NightWatch_3_Equivalent()
{
var nightWatch = new HumanMadeObject()
.WithContext()
.WithId("https://linked.art/example/object/nightwatch/3")
.WithLabel("Night Watch by Rembrandt");
nightWatch.Equivalent = [
new HumanMadeObject()
.WithId("https://www.wikidata.org/entity/Q219831")
.WithLabel("Night Watch")
];
return nightWatch;
}var humanMadeObject = new HumanMadeObject
{
Context = ["https://linked.art/ns/v1/linked-art.json"],
Id = "https://linked.art/example/object/nightwatch/3",
Label = "Night Watch by Rembrandt",
Equivalent =
[
new HumanMadeObject
{
Id = "https://www.wikidata.org/entity/Q219831",
Label = "Night Watch",
},
],
};Generated from the object the example builds: every property that is set, as object initialisers, with the vocabulary constants where a term is in the registry. The fluent helpers are a convenience, not a requirement; this form and the one as written produce the same JSON.
