Placeholders [VCon UG]
As a principle, Placeholders are considered as VidiCore Collections holding inheritable metadata.
There are different ways to deal with placeholders in VidiControl.
Create a new Recording based on a placeholder from VidiControl UI
On the timeline view, the Lane Header Context Menu, the Lane Context Menu and the Actions Menu offer possibilities to create a new recording based on a placeholder. This will open the collection search dialog:

Example
The URI
http://192.168.1.1/vidicontrol/create-booking-definition?placeholderId=COLLECTION-VX-27071
opens the Booking Dialogue with a pre-filled placeholder and metadata set:
