YoutubeChannel:
description: >-
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.
