AFAIK, from recent use, the description of the JSON descriptor on this
page is incorrect.
Would you like me to edit ?

Page Edited : SLING : Content Loading

Content:
Loading initial content from bundles
Repository items to be loaded into the repository, when the bundle
is first installed, may be defined in four ways:
• Directories
• Files
• XML descriptor files
• JSON descriptor files
Depending on the bundle entry found in the location indicated by the
Sling-Initial-Content bundle manifest header, nodes are created (and/
or updated) as follows:
Directories
Unless a node with the name of the directory already exists or has
been defined in an XML or JSON descriptor file (see below) a
directory is created as a node with the primary node type
"nt:folder" in the repository.
Files
Unless a node with the name of the file already exists or has been
defined in an XML or JSON descriptor file (see below) a file is
created as two nodes in the repository. The node bearing the name of
the file itself is created with the
primary node type "nt:file". Underneath this file node, a resource
node with the primary node type "nt:resource" is created, which is
set to the contents of the file.
The MIME type is derived from the file name extension by first
trying to resolve it from the Bundle entry URL. If this does not
resolve to a MIME type, the Sling MIME type resolution service is
used to try to find a mime type. If all fals, the MIME type is
defaulted to "application/octet-stream".
XML Descriptor Files
Nodes, Properties and in fact complete subtrees may be described in
XML files
using the following skeleton structure:
<node>
<!--
optional on top level, defaults to XML file name without .xml
extension
required for child nodes
-->
<name>xyz</name>
<!--
optional, defaults to nt:unstructured
-->
<primaryNodeType>nt:file</primaryNodeType>
<!--
optional mixin node type
may be repeated for multiple mixin node types
-->
<mixinNodeType>mix:versionable</mixinNodeType>
<mixinNodeType>mix:lockable</mixinNodeType>
<!--
Optional properties for the node. Each <property>
element defines
a single property of the node. The element may be
repeated.
-->
<property>
<!--
required property name
-->
<name>prop</name>
<!--
value of the property.
For multi-value properties, the values are
defined by multiple
<value> elements nested inside a <values>
element instead of a
single <value> element
-->
<value>property value as string</value>
<!--
Optional type of the property value, defaults
to String.
This must be one of the property type strings
defined in the
JCR PropertyType interface.
<type>String</type>
</property>
<!--
Additional child nodes. May be further nested.
-->
<node>
....
</node>
</node>
JSON Descriptor Files
Nodes, Properties and in fact complete subtrees may be described in
JSON files using the following skeleton structure (see http://www.json.org
or information on the syntax of JSON) :
{
// optional node name on top level, default is file name
without .json ext.
"name": "nodename",
// optional primary node type, default "nt:unstructured"
"primaryNodeType": "sling:ScriptedComponent",
// optional mixin node types as array
"mixinNodeTypes": [ ],
// the "properties" property is an object indexed by property
name whose
// value is either the string property value, array for multi-
values or
// an object whose value[s] property denotes the property
value(s) and
// whose type property denotes the property type
"properties": {
"sling:contentClass": "com.day.sling.jcr.test.Test",
"sampleMulti": [ "v1", "v2" ],
"sampleStruct": {
"value": 1,
"type": "Long"
}
"sampleStructMulti": {
"value": [ 1, 2, 3 ],
"type": "Long"
}
},
// the "nodes" property is an array of objects denoting child
nodes. Nodes
// may be further nested.
"nodes": [
{
// the name property is required on (nested)
child nodes
"name": "sling:scripts",
"primaryNodeType": "sling:ScriptList",
"nodes": [
{
"primaryNodeType":
"sling:Script",
"properties": {
"sling:name":
"/test/content/jsp/start.jsp",
"sling:type": "jsp",
"sling:glob": "*"
}
}
]
}
]
}
