出典: https://schema.org/AssignAction（英語。訳すと意味が変わることがあるため、原文のまま載せています）

どこに位置する型か

Thing → Action → OrganizeAction → AllocateAction → AssignAction

上にある型ほど広い意味です。書くときは、そのページに一番近い（下にある）型を選びます。

Googleのリッチリザルトに対応していますか？

公式ギャラリーには載っていません。ただし、載っていない型を書いてはいけないという意味ではありません。schema.org の語彙は、検索結果の見た目を変えるためだけのものではなく、ページが何について書かれているかを機械に伝えるためのものです。リッチリザルトが出るかどうかと、書いてよいかどうかは別の話です。

親の型から受け継ぐプロパティ（26個）

上の型で決まっているものは、この型でもそのまま使えます。

プロパティ	入る値の型	schema.org の説明（原文）	どの型から
`actionProcess`	HowTo	Description of the process by which the action was performed.	Action
`actionStatus`	ActionStatusType	Indicates the current disposition of the Action.	Action
`agent`	Organization、Person	The direct performer or driver of the action (animate or inanimate). E.g. John wrote a book.	Action
`endTime`	DateTime、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.	Action
`error`	Thing	For failed actions, more information on the cause of the failure. Consider using the Error type.	Action
`instrument`	Thing	The object that helped the agent perform the action. E.g. John wrote a book with a pen.	Action
`location`	Place、PostalAddress、Text、VirtualLocation	The location of, for example, where an event is happening, where an organization is located, or where an action takes place.	Action
`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.	Action
`participant`	Organization、Person	Other co-agents that participated in the action indirectly. E.g. John wrote a book with Steve.	Action
`provider`	Organization、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.	Action
`result`	Thing	The result produced in the action. E.g. John wrote a book.	Action
`startTime`	DateTime、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.	Action
`target`	EntryPoint、URL	Indicates a target EntryPoint, or url, for an Action.	Action
`additionalType`	Text、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.	Thing
`alternateName`	Text	An alias for the item.	Thing
`description`	Text、TextObject	A description of the item.	Thing
`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.	Thing
`identifier`	PropertyValue、Text、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.	Thing
`image`	ImageObject、URL	An image of the item. This can be a URL or a fully described ImageObject.	Thing
`mainEntityOfPage`	CreativeWork、URL	Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details.	Thing
`name`	Text	The name of the item.	Thing
`owner`	Organization、Person	A person or organization who owns this Thing.	Thing
`potentialAction`	Action	Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.	Thing
`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.	Thing
`subjectOf`	CreativeWork、Event	A CreativeWork or Event about this Thing.	Thing
`url`	URL	URL of the item.	Thing
