NAME
SemanticWeb::Schema::Offer - An offer to transfer some rights to an item or to provide a service — for example
VERSION
version v12.0.0
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 [[gtin]] property generalizes the earlier [[gtin8]], [[gtin12]], [[gtin13]], and [[gtin14]] properties. The GS1 digital link specifications express GTINs as URLs. 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.
A gtin should be one of the following types:

Str
_has_gtin12
A predicate for the "gtin12" attribute.
gtin13
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](http://www.gs1.org/barcodes/technical/idkeys/gtin) for more details.
A gtin13 should be one of the following types:
Str
_has_gtin13
A predicate for the "gtin13" attribute.

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.
