I'm looking for a way to retrieve the full schema for a specific site column using GetColumns as the source but using JQuery not the CSOM. I will then be using the schema for the single site column to add a new column to a set of lists using UpdateList.
I've tried writing out what I think would be the schema based on data I found for the site column but it doesn't behave. I believe it has to be an exact copy of the site column schema that you pass into UpdateList so I'd like to retrieve it using GetColumns.
Any help appreciated. Will be happy to post final code when working.
