The measuredProperty of an [Observation](https://schema.org/Observation), typically via its [StatisticalVariable](https://schema.org/StatisticalVariable). There are various kinds of applicable [Property](https://schema.org/Property): a schema.org property, a property from other RDF-compatible systems, e.g. W3C RDF Data Cube, Data Commons, Wikidata, or schema.org extensions such as [GS1's](https://www.gs1.org/voc/?show=properties).

A Global Trade Item Number ([GTIN](https://www.gs1.org/standards/id-keys/gtin)). GTINs identify trade items, including products and services, using numeric identification codes. A correct [gtin](https://schema.org/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](https://www.gs1.org/services/check-digit-calculator) and meet the other rules for valid GTINs. See also [GS1's GTIN Summary](http://www.gs1.org/barcodes/technical/idkeys/gtin) and [Wikipedia](https://en.wikipedia.org/wiki/Global_Trade_Item_Number) for more details. Left-padding of the gtin values is not required or encouraged. The [gtin](https://schema.org/gtin) property generalizes the earlier [gtin8](https://schema.org/gtin8), [gtin12](https://schema.org/gtin12), [gtin13](https://schema.org/gtin13), and [gtin14](https://schema.org/gtin14) properties. The GS1 [digital link specifications](https://www.gs1.org/standards/Digital-Link/) expresses GTINs as URLs (URIs, IRIs, etc.). Digital Links should be populated into the [hasGS1DigitalLink](https://schema.org/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.
