As you can see the screenshot regarding "Blueprint Control Center", I can see there has many status about pages live copy, but I cannot find the relationship in /crx/de path, I know somewhere saving the relationship and maintenance.
I mean why Blueprint knows there has two site ca/en, us/en reference by language-masters/en? It definitely somewhere saving the data.
This is set on jcr:content nodes and define root Livecopy pages . Those pages will have a cq:LiveSyncConfig child node of type cq:LiveCopy that will contain basic and mandatory information on the Livecopy through the following properties:
cq:master : points to the Blueprint page of the Livecopy cq:rolloutConfigs : indicates active Rollout Configurations applied on the Livecopy cq:isDeep : is true if the child pages of this root Livecopy page are included in the Livecopy.
- cq:LiveRelationship mixin type
Any livecopy page has such a mixin type on its jcr:content node. If not, the page has been at some point detached, or manually created via the authoring interface outside of a Livecopy action (create or rollout)
- cq:LiveSyncCancelled mixin type
Added on jcr:content nodes of Livecopy pages that were suspended.
If the suspension if effective for child pages as well : a cq:isCancelledForChildren=true property is added on the same node.
