Offer

Schema.org definition: 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 property, which identifies the form of offer (e.g. sell, lease, repair, dispose), defaults to http://purl.org/goodrelations/v1#Sell; an Offer without a defined businessFunction value can be assumed to be an offer to sell.

For GTIN-related fields, see Check Digit calculator and validation guide from GS1.

Properties

Property Description
sameAs 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.
from class http://schema.org/Thing
alternateName An alias for the item.
from class http://schema.org/Thing
description A description of the item.
from class http://schema.org/Thing
name The name of the item.
from class http://schema.org/Thing
url URL of the item.
from class http://schema.org/Thing
image An image of the item. This can be a URL or a fully described ImageObject.
from class http://schema.org/Thing
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 for more details.
from class http://schema.org/Thing
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.
from class http://schema.org/Thing
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.
from class http://schema.org/Thing
mainEntityOfPage Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details.
from class http://schema.org/Thing
availability The availability of this item—for example In stock, Out of stock, Pre-order, etc.
from class http://schema.org/Offer
price The offer price of a product, or of a price component when attached to PriceSpecification and its subtypes.

Usage guidelines:

  • Use the priceCurrency property (with standard formats: ISO 4217 currency format e.g. "USD"; Ticker symbol for cryptocurrencies e.g. "BTC"; well known names for Local Exchange Tradings Systems (LETS) and other currency types e.g. "Ithaca HOUR") instead of including ambiguous symbols such as '$' in the value.
  • Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator.
  • Note that both RDFa and Microdata syntax allow the use of a "content=" attribute for publishing simple machine-readable values alongside more human-friendly formatting.
  • Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similiar Unicode symbols.
