== JSON Documents: Basics==

What is a JSON?
* A JSON itself is a JSON object, marked by [https://json-schema.org/understanding-json-schema/basics.html#hello-world]

<syntaxhighlight lang="json">
{}
</syntaxhighlight>

==JSON Documents: Key-Value-Pairs==

*A JSON object defines key(word):value pairs.
*Keys are formatted as strings, marked by quotation marks ("").

<syntaxhighlight lang="json">
{
"key": "value"
}
</syntaxhighlight>

==JSON Documents: Data types==

*The key is always a string
*The value can be a string, a number, a boolean or null
*Additional data types are only possible by referencing them as external resources

<syntaxhighlight lang="json">
{
"key": "value",
"string": "any string value",
"number": 1.0,
"bool": true,
"empty": null,
"image": "https://my.cloud/image-1.png"
}
</syntaxhighlight>

==JSON Documents: Subobjects==

*The value can also be a JSON document (object) itself
*A nested object can have the same key-value pairs as the root document
*There is no limit in the nesting depth

<syntaxhighlight lang="json">
{
"key": "value",
"string": "any string value",
"number": 1.0,
"bool": true,
"empty": null,
"object": {
"has": "it's own key-value-pairs"
}
}
</syntaxhighlight>

==JSON Documents: Arrays==

*The value can also be an array (list)
*An array can contain any element, including objects and nested arrays

<syntaxhighlight lang="json">
{
"key": "value",
"string": "any string value",
"number": 1.0,
"bool": true,
"empty": null,
"object": {
"has": "it's own key-value-pairs"
},
"array": [
"a list",
{"of": "any"},
["item1", 1.0, true]
]
}
</syntaxhighlight>

==JSON Documents: Pointer (1)==

Pointer allow reference to
*An object within the JSON document

<syntaxhighlight lang="json">
{
"firstname": "Susan",
"surname": "Birch",
"kids": ["Anne", "Tom"],
"emergency_contact": {
"$ref": "#/kids/0"
}
}
</syntaxhighlight>
Syntax [https://www.rfc-editor.org/rfc/rfc6901]:

<nowiki>#</nowiki> - the whole document = self-reference

<nowiki>#</nowiki>/kids - the value of the key "kids"

<nowiki>#</nowiki>/kids/0 - the first item within the array "kids"
==JSON Documents: Pointer (2)==
Pointer allow reference to
*An object within the JSON document
*An external JSON document

<syntaxhighlight lang="json">
{
"firstname": "Susan",
"surname": "Birch",
"partner": {
"$ref": "http://www.personaldata.com/walter.birch.json"
}
}
</syntaxhighlight>
