Add actor to PodcastSeries

[gmackenz]

actor is already present almost every videogame, visual, and audio episodic and series types except for PodcastSeries. This request is based on active efforts within Google to support cast information for podcast feeds at the episode and series level. I expect this to be actively used in the near future.

Something to ponder :
It seems to me we could land a lot of these commonly used properties (i.e. actor, director, etc.) on a type we are currently missing between CreativeWork/CreativeWorkSeries and the TV, Movie, Radio, Podcast, and VideoGame instance and series types

Closing this in favour of #2899.

@danbri Is actor intended to be the host of the podcast? Or perhaps it's for potential guests of the show?

The reason I ask is that the docs don't seem to specify what the actor property would be in the context of a podcast.

While I haven't heard podcast hosts referred to as "actors", and not all podcasts have guests, but this is a new property not present in CreativeWorkSeries, and I'm not sure. For the host, I would naturally use author.

Some more context would be very helpful. Much obliged.

That was the intent to use the actor property to supply the person with a specific role for their appearance on the podcast. I know of at least one podcast started by one person and then later on a new person took over the hosting role while the original creator/host (who certainly could be listed as author in that context) became a producer.

We should have some examples on podcast to represent the usage.

Makes sense, thank you for clarifying. I'll use author for the creator/host and actor for any guests who may appear in specific episodes.
