Property	Expected Type	Description
Properties from CommentAction
`resultComment`	Comment	A sub property of result. The Comment created or sent as a result of this action.
Properties from CommunicateAction
`about`	Thing	The subject matter of an object. Inverse property: subjectOf
`inLanguage`	Language or Text	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. See also availableLanguage. Supersedes language.
`recipient`	Audience or ContactPoint or Organization or Person	A sub property of participant. The participant who is at the receiving end of the action.
Properties from Action
`actionProcess`	HowTo	Description of the process by which the action was performed.
`actionStatus`	ActionStatusType	Indicates the current disposition of the Action.
`agent`	Organization or Person	The direct performer or driver of the action (animate or inanimate). E.g. John wrote a book.
`endTime`	DateTime or Time	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. Note that Event uses startDate/endDate instead of startTime/endTime, even when describing dates with times. This situation may be clarified in future revisions.
`error`	Thing	For failed actions, more information on the cause of the failure. Consider using the Error type.
`instrument`	Thing	The object that helped the agent perform the action. E.g. John wrote a book with a pen.
`location`	Place or PostalAddress or Text or VirtualLocation	The location of, for example, where an event is happening, where an organization is located, or where an action takes place.
`object`	Thing	The object upon which the action is carried out, whose state is kept intact or changed. Also known as the semantic roles patient, affected or undergoer (which change their state) or theme (which doesn't). E.g. John read a book.
`participant`	Organization or Person	Other co-agents that participated in the action indirectly. E.g. John wrote a book with Steve.
`provider`	Organization or Person	The service provider, service operator, or service performer; the goods producer. Another party (a seller) may offer those services or goods on behalf of the provider. A provider may also serve as the seller. Supersedes carrier.
`result`	Thing	The result produced in the action. E.g. John wrote a book.
`startTime`	DateTime or Time	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. Note that Event uses startDate/endDate instead of startTime/endTime, even when describing dates with times. This situation may be clarified in future revisions.
`target`	EntryPoint or URL	Indicates a target EntryPoint, or url, for an Action.
Properties from Thing
`additionalType`	Text or URL	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. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org style guide.
`alternateName`	Text	An alias for the item.
`description`	Text or TextObject	A description of the item.
`disambiguatingDescription`	Text	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.
`identifier`	PropertyValue or Text or URL	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 for more details.
`image`	ImageObject or URL	An image of the item. This can be a URL or a fully described ImageObject.
`mainEntityOfPage`	CreativeWork or URL	Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details. Inverse property: mainEntity
`name`	Text	The name of the item.
`owner`	Organization or Person	A person or organization who owns this Thing. Inverse property: owns
`potentialAction`	Action	Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.
`sameAs`	URL	URL of a reference Web page that unambiguously indicates the item's identity. E.g. the URL of the item's Wikipedia page, Wikidata entry, or official website.
`subjectOf`	CreativeWork or Event	A CreativeWork or Event about this Thing. Inverse property: about
`url`	URL	URL of the item.
