55:       ddl.entities[:data][:output].include?(output.to_sym) rescue false
56:     end

For an input where the DDL requests a boolean or some number this will convert the input to the right type where possible else just returns the origin input unedited

if anything here goes wrong just return the input value this is not really the end of the world or anything since all that will happen is that DDL validation will fail and the user will get an error, no need to be too defensive here
