Data are the core puzzle element. In this specific section, the focus is qualitative video data that defines a group of data that shares certain characteristics and are handled in a similar way.
You can have as many data elements that you like. E.g. you can have a data element representing a collection of videos, one that represent a single video, one representing a publised version of a video.
The level of abstracion is what makes sense to you. If you apply different processes for one part of the data, and not for another part this might be the determining factor if these two should be divided.
