The subject matter of the content.

An actor, e.g. in tv, radio, movie, video games etc., or in an event. Actors can be associated with individual items or with a series, episode, clip.

An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. In RDFa syntax, it is better to use the native RDFa syntax - the 'typeof' attribute - for multiple types. Schema.org tools may have only weaker understanding of extra types, in particular those defined externally.

The overall rating, based on a collection of reviews or ratings, of the item.

An alias for the item.

A person attending the event.

An intended audience, i.e. a group for whom something was created.

The eventAttendanceMode of an event indicates whether it occurs online, offline, or a mix.

Associates an [Event](http://schema.org/Event) with a [Schedule](http://schema.org/Schedule). There are circumstances where it is preferable to share a schedule for a series of repeating events rather than data on the individual events themselves. For example, a website or application might prefer to publish a schedule for a weekly gym class rather than provide data on every event. A schedule could be processed by applications to add forthcoming events to a calendar. An [Event](http://schema.org/Event) that is associated with a [Schedule](http://schema.org/Schedule) using this property should not have [startDate](http://schema.org/startDate) or [endDate](http://schema.org/endDate) properties. These are instead defined within the associated [Schedule](http://schema.org/Schedule), this avoids any ambiguity for clients using the data. The property might have repeated values to specify different schedules, e.g. for different months or seasons.

An eventStatus of an event represents its status; particularly useful when an event is cancelled or rescheduled.

A person or organization that supports (sponsors) something through some kind of financial contribution.

The identifier property represents any kind of identifier for any kind of [Thing](http://schema.org/Thing), such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See [background notes](https://schema.org/docs/datamodel.html#identifierBg) for more details.

The maximum physical attendee capacity of an [Event](http://schema.org/Event) whose [eventAttendanceMode](http://schema.org/eventAttendanceMode) is [OnlineEventAttendanceMode](http://schema.org/OnlineEventAttendanceMode) (or the online aspects, in the case of a [MixedEventAttendanceMode](http://schema.org/MixedEventAttendanceMode)).

Use [businessFunction](http://schema.org/businessFunction) to indicate the kind of transaction offered, i.e. sell, lease, etc. This property can also be used to describe a [Demand](http://schema.org/Demand). While this property is listed as expected on a number of common types, it can be used in others. In that case, using a second type, such as Product or a subtype of Product, can clarify the nature of the offer.
