to go further: let’s say i don’t even define a purpose for the app but just leave it open to users to define their metadata labeling scheme and all the app does is index the videos labeled in a common way. perhaps endusers agree on redit or on some wiki how they will label posts. the app just traverses the labeling scheme and provides some basic viewing and searching locally; without a server involved beyond youtube. i’m just wondering whether this new situation essentially criminalizes metadata.
