I am implementing mr Kim's paper for text classification in order to do obviously some text classification.

Now my question is that I some short meta data for each text such editors , sources and text subject.

Let's say for instance that I have one or multiple editors and that I wanted to add them to the CNN. At which layer of the CNN should I add this input?
