NAME

SemanticWeb::Schema::Offer - An offer to transfer some rights to an item or to provide a service — for example

VERSION

version v23.0.0

DESCRIPTION

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.

gtin

A Global Trade Item Number (GTIN). GTINs identify trade items, including products and services, using numeric identification codes.

The GS1 digital link specifications express GTINs as URLs (URIs, IRIs, etc.). Details including regular expression examples can be found in, Section 6 of the GS1 URI Syntax specification; see also schema.org tracking issue for schema.org-specific discussion. 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.

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.

mobile_url

mobileUrl

The [[mobileUrl]] property is provided for specific situations in which data consumers need to determine whether one of several provided URLs is a dedicated 'mobile site'.

To discourage over-use, and reflecting intial usecases, the property is expected only on SemanticWeb::Schema::Product and SemanticWeb::Schema::Offer, rather than SemanticWeb::Schema::Thing. The general trend in web technology is towards responsive design in which content can be flexibly adapted to a wide range of browsing environments. Pages and sites referenced with the long-established [[url]] property should ideally also be usable on a wide variety of devices, including mobile phones. In most cases, it would be pointless and counter productive to attempt to update all [[url]] markup to use [[mobileUrl]] for more mobile-oriented pages. The property is intended for the case when items (primarily SemanticWeb::Schema::Product and SemanticWeb::Schema::Offer) have extra URLs hosted on an additional "mobile site" alongside the main one. It should not be taken as an endorsement of this publication style.

A mobile_url should be one of the following types:

Str

A predicate for the "mobile_url" attribute.

A predicate for the "offered_by" attribute.

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 Trading 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 similar Unicode symbols.
