## Used on Types

| Type | Description |
|------|-------------|
| [ActionAccessSpecification](https://schema.org.ai/ActionAccessSpecification) | A set of requirements that must be fulfilled in order to perform an Action. |
| [Demand](https://schema.org.ai/Demand) | A demand entity represents the public, not necessarily binding, not necessarily exclusive, announcement by an organization or person to seek a certain type of goods or services. For describing demand using this type, the very same properties used for Offer apply. |
| [Offer](https://schema.org.ai/Offer) | An offer to transfer some rights to an item or to provide a service — for example, an offer to sell tickets to an event, to rent the DVD of a movie, to stream a TV show over the internet, to repair a motorcycle, or to loan a book. Note: As the [businessFunction](https://schema.org.ai/businessFunction) property, which identifies the form of offer (e.g. sell, lease, repair, dispose), defaults to [http://purl.org/goodrelations/v1#Sell](http://purl.org/goodrelations/v1#Sell); an Offer without a defined businessFunction value can be assumed to be an offer to sell. For [GTIN](http://www.gs1.org/barcodes/technical/idkeys/gtin)-related fields, see [Check Digit calculator](http://www.gs1.org/barcodes/support/check_digit_calculator) and [validation guide](http://www.gs1us.org/resources/standards/gtin-validation-guide) from [GS1](http://www.gs1.org/). |
