Hi Ian, TL;DR this should not be difficult to do within a validation function, *but* you might find performance takes a hit. I have some old links on this but don't recall anybody posting anything concrete, and I found a way not to need it. http://mail-archives.apache.org/mod_mbox/couchdb-user/201104.mbox/%[email protected]%3E This person had a crack but never revealed any secret sauce: http://daemon.co.za/2012/05/dynamic-forms-json-schema/ http://daemon.co.za/2012/05/replacing-couchdb-views-with-elasticsearch/ Simon might have more details to share: https://cloudant.com/blog/schemas-in-couchdb/ >From a performance perspective you are likely to find this painful. https://github.com/k3nn7/json-validator Would likely work as an erlang validation function, with some work required. But at least its mochiweb based already. A+ Dave
