InformAction

The act of notifying someone of information pertinent to them, with no expectation of a response.

A sub property of participant. The participant who is at the receiving end of the action.

inLanguage

The language of the content or performance or used in an action. Please use one of the language codes from the [IETF BCP 47 standard](http://tools.ietf.org/html/bcp47). See also [[availableLanguage]].

startTime

The startTime of something. For a reserved event or service (e.g. FoodEstablishmentReservation), the time that it is expected to start. For actions that span a period of time, when the action was performed. e.g. John wrote a book from *January* to December. For media, including audio and video, it's the time offset of the start of a clip within a larger file.\n\nNote that Event uses startDate/endDate instead of startTime/endTime, even when describing dates with times. This situation may be clarified in future revisions.

location

The location of, for example, where an event is happening, where an organization is located, or where an action takes place.

event

Upcoming or past event associated with this place, organization, or action.

endTime

The endTime of something. For a reserved event or service (e.g. FoodEstablishmentReservation), the time that it is expected to end. For actions that span a period of time, when the action was performed. e.g. John wrote a book from January to *December*. For media, including audio and video, it's the time offset of the end of a clip within a larger file.\n\nNote that Event uses startDate/endDate instead of startTime/endTime, even when describing dates with times. This situation may be clarified in future revisions.

about

subjectOf

A CreativeWork or Event about this Thing.

language

A sub property of instrument. The language used on this action.

identifier

The identifier property represents any kind of identifier for any kind of [[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](/docs/datamodel.html#identifierBg) for more details.

name

The name of the item.

mainEntityOfPage

Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See [background notes](/docs/datamodel.html#mainEntityBackground) for details.

participant

image

An image of the item. This can be a [[URL]] or a fully described [[ImageObject]].

disambiguatingDescription

A sub property of description. A short description of the item used to disambiguate from other, similar items. Information from other properties (in particular, name) may be necessary for the description to be useful for disambiguation.

A description of the item.

agent

The direct performer or driver of the action (animate or inanimate). e.g. *John* wrote a book.

additionalType

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.

url

URL of the item.

target

Indicates a target EntryPoint for an Action.

sameAs

error

For failed actions, more information on the cause of the failure.

alternateName

An alias for the item.

actionStatus

Indicates the current disposition of the Action.

Action

An action performed by a direct agent and indirect participants upon a direct object. Optionally happens at a location with the help of an inanimate instrument. The execution of the action may produce a result. Specific action sub-type documentation specifies the exact expectation of each argument/role.\n\nSee also [blog post](http://blog.schema.org/2014/04/announcing-schemaorg-actions.html) and [Actions overview document](https://schema.org/docs/actions.html).
