YouTube channel metadata including channel ID, title, description,

subscriber/video/view counts, country code, and branding URLs.
|

|
Ontology mapping rationale:
|
|
- class_uri is schema:BroadcastChannel because a YouTube channel is
|
|
a broadcast channel for video content distribution.
|
|
- close_mappings includes foaf:OnlineAccount as a channel represents
|
|
an online account on YouTube.
|
|
- related_mappings includes schema:Organization as channels often
|
|
represent institutional presence, and prov:Entity for tracking.
