Hey just for my understanding, do you want to show external Information inside a Dendron note? Like you have the Hierarchy like in your screenshot, but in the Note for

Charts.Deezer.Monthly.Worldwide.2020.01.

you want to be able to show the actual Chart from where ever that is. This should already be possible, will need to test it if dendron Allows

raw Html Iframes

for the preview / publishing to be inside of notes. Ahhh.... stop reread your message, something like that could be done per Pods to import the charts, creating the Hierarchy. Like one Pod to import the Charts from Deezer for month X, running that pod once a month would add the charts of the last month to it. Since these Charts are

static

they don't change. But it could generate a Scaffold for live Charts for the Genres as example which would just link or embed the Corresponding Charts. But this would not allow for the needed editing to Link an an Artist in the Live Charts to the Notes about the Artist. This would be possible for the monthly Charts since these are Static and could be analysed to create the needed links towards the Notes about Artist’s or Albums. Interesting Idea overall.
