Repeated lecture in "Epsilon Devs" Youtube channel

[StephenF55]

I noticed that the following two Epsilon Devs videos on YouTube both cover the same lecture:

• Introduction to Model Querying, Validation and Transformation with Epsilon
• Introduction to Model Validation and Code Generation with Epsilon

As you may be aware, the two video's are not completely identical, as they differ in the positioning of the 'lecturer' thumbnail. With the latter video having much the better placement, as this does not obscure the slide content (unlike the former, which does).

So I wonder would it be possible to remove the redundant 'bad' version of this lecture?

I was also slightly puzzled about the lecture that precedes it. Is this the video entitled Design and Implementation of Graphical Syntaxes? Or is there perhaps another missing lecture video that introduces EMF & Emfatic (as referenced at the very start of this lecture)

Well spotted! I've removed the redundant version of the lecture.

You are correct in that there was also a lecture on EMF and Emfatic but unfortunately, I no longer have the recorded video. However, EMF and Emfatic are also covered in this lecture.

Many thanks Dimitris.
