About#

JSON-LD fully support the identification of the language types.

Properties such as label, description, keyword etc can be extended in the context with a container language attribute notiation.

This will allow the use of standard language codes (fr, es, en, de, etc) to be used when describing these properties. A list of codes can be seen at the [Online Browsing Platform (OBP)](https://www.iso.org/obp/ui/#search and) and Popular standards ISO 3166 Country Codes. You should use the 2-letter codes as demonstrated below.

 1{
 2    "@context": {
 3      "vocab": "http://example.com/vocab/",
 4      "label": {
 5        "@id": "vocab:label",
 6        "@container": "@language"
 7      }
 8    },
 9    "@id": "http://example.com/queen",
10    "label": {
11      "en": "The Queen",
12      "de": [ "Die Königin", "Ihre Majestät" ]
13    }
14  }

In graph space the resulting triples from the above are:

<http://example.com/queen> <http://example.com/vocab/label> "Die Königin"@de .
<http://example.com/queen> <http://example.com/vocab/label> "Ihre Majestät"@de .
<http://example.com/queen> <http://example.com/vocab/label> "The Queen"@en .

with language encoding attributes in place. These can be used in searching and result filters.

Note, this can cause issues in query space since the concept of

"Semua orang dilahirkan merdeka dan mempunyai martabat dan hak-hak yang sama. 
Mereka dikaruniai akal dan hati nurani dan hendaknya bergaul satu 
sama lain dalam semangat persaudaraan."

and

"Semua orang dilahirkan merdeka dan mempunyai martabat 
dan hak-hak yang sama. Mereka dikaruniai akal dan hati nurani 
dan hendaknya bergaul satu sama lain dalam semangat persaudaraan."@id

are different and so care must be taken the creation of the SPARQL queries not to accidentally imposed implicate filters through the use of language types.
