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.

Property	Expected Type	Description
Properties from Demand
`acceptedPaymentMethod`	LoanOrCredit or PaymentMethod or Text	The payment method(s) that are accepted in general by an organization, or for some specific demand or offer.
`advanceBookingRequirement`	QuantitativeValue	The amount of time that is required between accepting the offer and the actual usage of the resource or service.
`areaServed`	AdministrativeArea or GeoShape or Place or Text	The geographic area where a service or offered item is provided. Supersedes serviceArea.
`asin`	Text or URL	An Amazon Standard Identification Number (ASIN) is a 10-character alphanumeric unique identifier assigned by Amazon.com and its partners for product identification within the Amazon organization (summary from Wikipedia's article). Note also that this is a definition for how to include ASINs in Schema.org data, and not a definition of ASINs in general - see documentation from Amazon for authoritative details. ASINs are most commonly encoded as text strings, but the [asin] property supports URL/URI as potential values too.
`availability`	ItemAvailability	The availability of this item—for example In stock, Out of stock, Pre-order, etc.
`availabilityEnds`	Date or DateTime or Time	The end of the availability of the product or service included in the offer.
`availabilityStarts`	Date or DateTime or Time	The beginning of the availability of the product or service included in the offer.
`availableAtOrFrom`	Place	The place(s) from which the offer can be obtained (e.g. store locations).
`availableDeliveryMethod`	DeliveryMethod	The delivery method(s) available for this offer.
`businessFunction`	BusinessFunction	The business function (e.g. sell, lease, repair, dispose) of the offer or component of a bundle (TypeAndQuantityNode). The default is http://purl.org/goodrelations/v1#Sell.
`deliveryLeadTime`	QuantitativeValue	The typical delay between the receipt of the order and the goods either leaving the warehouse or being prepared for pickup, in case the delivery method is on site pickup.
`eligibleCustomerType`	BusinessEntityType	The type(s) of customers for which the given offer is valid.
`eligibleDuration`	QuantitativeValue	The duration for which the given offer is valid.
`eligibleQuantity`	QuantitativeValue	The interval and unit of measurement of ordering quantities for which the offer or price specification is valid. This allows e.g. specifying that a certain freight charge is valid only for a certain quantity.
`eligibleRegion`	GeoShape or Place or Text	The ISO 3166-1 (ISO 3166-1 alpha-2) or ISO 3166-2 code, the place, or the GeoShape for the geo-political region(s) for which the offer or delivery charge specification is valid. See also ineligibleRegion.
`eligibleTransactionVolume`	PriceSpecification	The transaction volume, in a monetary unit, for which the offer or price specification is valid, e.g. for indicating a minimal purchasing volume, to express free shipping above a certain order volume, or to limit the acceptance of credit cards to purchases to a certain minimal amount.
`gtin`	Text or URL	A Global Trade Item Number (GTIN). GTINs identify trade items, including products and services, using numeric identification codes. A correct gtin value should be a valid GTIN, which means that it should be an all-numeric string of either 8, 12, 13 or 14 digits, or a "GS1 Digital Link" URL based on such a string. The numeric component should also have a valid GS1 check digit and meet the other rules for valid GTINs. See also GS1's GTIN Summary and Wikipedia for more details. Left-padding of the gtin values is not required or encouraged. The gtin property generalizes the earlier gtin8, gtin12, gtin13, and gtin14 properties. The GS1 digital link specifications expresses GTINs as URLs (URIs, IRIs, etc.). Digital Links should be populated into the hasGS1DigitalLink attribute. Note also that this is a definition for how to include GTINs in Schema.org data, and not a definition of GTINs in general - see the GS1 documentation for authoritative details.
`gtin12`	Text	The GTIN-12 code of the product, or the product to which the offer refers. The GTIN-12 is the 12-digit GS1 Identification Key composed of a U.P.C. Company Prefix, Item Reference, and Check Digit used to identify trade items. See GS1 GTIN Summary for more details.
`gtin13`	Text	The GTIN-13 code of the product, or the product to which the offer refers. This is equivalent to 13-digit ISBN codes and EAN UCC-13. Former 12-digit UPC codes can be converted into a GTIN-13 code by simply adding a preceding zero. See GS1 GTIN Summary for more details.
`gtin14`	Text	The GTIN-14 code of the product, or the product to which the offer refers. See GS1 GTIN Summary for more details.
`gtin8`	Text	The GTIN-8 code of the product, or the product to which the offer refers. This code is also known as EAN/UCC-8 or 8-digit EAN. See GS1 GTIN Summary for more details.
`includesObject`	TypeAndQuantityNode	This links to a node or nodes indicating the exact quantity of the products included in an Offer or ProductCollection.
`ineligibleRegion`	GeoShape or Place or Text	The ISO 3166-1 (ISO 3166-1 alpha-2) or ISO 3166-2 code, the place, or the GeoShape for the geo-political region(s) for which the offer or delivery charge specification is not valid, e.g. a region where the transaction is not allowed. See also eligibleRegion.
`inventoryLevel`	QuantitativeValue	The current approximate inventory level for the item or items.
`itemCondition`	OfferItemCondition	A predefined value from OfferItemCondition specifying the condition of the product or service, or the products or services included in the offer. Also used for product return policies to specify the condition of products accepted for returns.
`itemOffered`	AggregateOffer or CreativeWork or Event or MenuItem or Product or Service or Trip	An item being offered (or demanded). The transactional nature of the offer or demand is documented using businessFunction, e.g. sell, lease etc. While several common expected types are listed explicitly in this definition, others can be used. Using a second type, such as Product or a subtype of Product, can clarify the nature of the offer. Inverse property: offers
`mpn`	Text	The Manufacturer Part Number (MPN) of the product, or the product to which the offer refers.
`priceSpecification`	PriceSpecification	One or more detailed price specifications, indicating the unit price and delivery or payment charges.
`seller`	Organization or Person	An entity which offers (sells / leases / lends / loans) the services / goods. A seller may also be a provider. Supersedes vendor, merchant.
`serialNumber`	Text	The serial number or any alphanumeric identifier of a particular product. When attached to an offer, it is a shortcut for the serial number of the product included in the offer.
`sku`	Text	The Stock Keeping Unit (SKU), i.e. a merchant-specific identifier for a product or service, or the product to which the offer refers.
`validFrom`	Date or DateTime	The date when the item becomes valid.
`validThrough`	Date or DateTime	The date after when the item is not valid. For example the end of an offer, salary period, or a period of opening hours.
`warranty`	WarrantyPromise	The warranty promise(s) included in the offer. Supersedes warrantyPromise.
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.
`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.

Instances of Demand may appear as a value for the following properties

Property	On Types	Description
offers	AggregateOffer or CreativeWork or EducationalOccupationalProgram or Event or MenuItem or Product or Service or Trip	An offer to provide this item—for example, an offer to sell a product, rent the DVD of a movie, perform a service, or give away tickets to an event. Use businessFunction to indicate the kind of transaction offered, i.e. sell, lease, etc. This property can also be used to describe a 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.
seeks	Organization or Person	A pointer to products or services sought by the organization or person (demand).
