By default, arrays in JSON-LD do not convey any ordering of contained elements. + However, for the processing of contexts, the ordering of elements in arrays does matter. + As such, when writing array-based contexts, this fact should be kept in mind.
+Ordered contexts in arrays allow inheritance and overriding of context entries.
+ When processing the following example, the first name entry will be overridden by the second name entry.
+ {
+ "@context": [
+ {
+ "id": "@id",
+ "name": "http://schema.org/name"
+ },
+ {
+ "name": "http://xmlns.com/foaf/0.1/name"
+ }
+ ],
+ "@id": "http://www.wikidata.org/entity/Q76",
+ "name": "Barack Obama"
+ }
+
+ Order is important when processing protected terms. + While the first example will cause a term redefinition error, the second example will not throw this error.
