I see we have a Gateway article for example configuration, documentation for the manifest.json file for Add-On packages, and good examples by @vantonenko on GitHub.

But is there a JSON schema of sorts or list of the manifest options, specifically for properties like EXTENSIONTYPE and EXTENSIONVERSION. Also, do paths use forward ("/") or back ("\") slash?

Ideally, it'd be nice to be able to create and edit the Add-On manifest.json file with auto-completing intellisense, but a list of valid options would be helpful as well.

I'm adding a Community wiki to gather examples and known details. Feel free to add to this or add an answer if there is a Schema for the manifest file format for Add-ons.


The list of type options are documented under Extension Types and includes, as of Tridion Sites 9.6:

  • CMApplicationDataConfiguration
  • Connector
  • CDDeployerExtension
  • CDModelTransformerExtension
  • CMResolver
  • ECLProvider
  • CMEventHandler
  • UIEditor
  • UIModel
  • CDGraphQLSchemaExtension
  • CDMergeableConfigurationExtension
  • CMApplicationDataConfiguration

Use "\" for local paths

In the Application Data Configuration Extension documentation you can see a file referenced using double back slash:

  "type": "CMApplicationDataConfiguration",
  "properties": {
    "xmlFileName": "CM\\MyCustomAppDataConfig.xml"

The MyCustomAppDataConfig.xml app data configuration file is placed in a folder named "CM" in the Add-on ZIP file.

Yet Another Example

Here's the manifest file format per the documentation.

  "manifestVersion": "MANIFESTVERSION",
  "version": "ADDONVERSION",
  "requireConfiguration": "CONFIGREQUIREMENT",
  "author": "AUTHORNAME",
  "description": "DESCRIPTION",
  "icon": "ICONIMAGEFILE",
  "extensions": [

Here's an example from demos and training.

  "manifestVersion": "1.0",
  "id": "SchemaRenamer",
  "version": "1.0",
  "name": "SchemaRenamer",
  "description": "Event System Extension",
  "icon": "Renamer.png",
  "author": "Demo User",
  "requireConfiguration": "Yes",
  "extensions": [
      "name": "TCMExtension",  
      "type": "CMEventHandler",
      "properties": {
            "assemblyFileSource": "EventSystemExtension.dll"
