Where to find AEM docs ??

Q1)  For every cq:Page  we need a jcr:content


I get that there are rules/schemas defined 

 

[cq:Page] > nt:hierarchyNode
  orderable primaryitem jcr:content
  + jcr:content (nt:base) = nt:unstructured
  + * (nt:base) = nt:base version

where are these defined in the jcr repository.
Where are the nt:nodeType nodes defined in the jcr repo ??

 

 

Q2) What are all the in-built/ used properties for a particular node type in AEM ?? Like for cq:Dialog we can define cq:Widget as a child node . Are there other possible meaningful child nodes for cq:Dialog ??? Where can I find documentation for the same ???

Hi@kunalna1 

 

  1. JCR node types can be checked put here: https://developer.adobe.com/experience-manager/reference-materials/spec/jcr/2.0/index.html
  2. Sling node types can be checked out here: https://cwiki.apache.org/confluence/display/SLING/Sling+Node+Types
  3. Custom node types, that AEM brings in, can be check out here: https://experienceleague.adobe.com/en/docs/experience-manager-65/content/implementing/developing/platform/custom-nodetypes. These can also be seen in CRX at /jcr:system/jcr:nodeTypes path
  4. I have also bumped into this. Never used it. But maybe you find it useful: https://github.com/Netcentric/aem-nodetypes/blob/master/src/main/resources/aem.cnd. You can look at the whole project to see what it does.

Hi @kunalna1 

Node definations are find in the CND files

https://jackrabbit.apache.org/jcr/node-type-notation.html

 

You can go to localhost:4502/crx/explorer/ and login to check all the node types

      Hi @kunalna1 

      Node types (like cq:Page) are defined in the Oak repository and managed under the node type registry. You can find definitions in the

      /libs/crx-quickstart/repository/nodetypes

      directory in the JCR, or through configuration files in 

      /libs or /apps

      in AEM.

      To find in-built properties and child nodes for cq:Dialog:

      • Check AEM documentation on Dialogs and Components.
      • Use the CRX/DE browser to inspect nodes like /libs/cq/dialog to explore child nodes like cq:Widget.
      • Use the AEM API to programmatically query properties and child nodes.
