Individual YouTube video metadata including video ID, title, description,

Ontology mapping rationale:
|
|
- class_uri is schema:VideoObject because this represents a video
|
|
as a media object on YouTube.
|
|
- close_mappings includes schema:MediaObject as the broader media
|
|
object category.
|
|
- related_mappings includes prov:Entity for provenance tracking and
|
|
schema:CreativeWork as videos are creative works.
