mber)'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

The GS1 L<digital link specifications|https://www.gs1.org/standards/Digital-Link/> 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 L<schema.org tracking issue|https://github.com/schemaorg/schemaorg/issues/3156#issuecomment-1209522809> 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 L<valid GS1 check digit|https://www.gs1.org/services/check-digit-calculator> and meet the other rules for valid GTINs. See also L<GS1's GTIN Summary|http://www.gs1.org/barcodes/technical/idkeys/gtin> and L<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]] property generalizes the earlier [[gtin8]], [[gtin12]], [[gtin13]], and [[gtin14]] properties.
