Introduction
New schema types: Podcast and PodcastEpisode.
Podcasts are part of the common Internet slang for more than 10 years, they are everywhere, they are slowly becoming very popular, but they are not quite well represented by the Semantic Web.
So far, if anyone wanted to classify a podcast page, it suppose to use a generic “CreativeWork” type for the list of content and an “Episode” type for each instance. Expanding CreativeWork into “Podcast” type gives it the proper meaning, plus a few useful properties, and, specifying Episode into “PodcastEpisode” makes clear the difference between it and other episodes (RadioEpisode/TVEpisode).
