IRI for schema:asin [Expects: https://schema.org/Text, https://schema.org/URL]
An Amazon Standard Identification Number (ASIN) is a 10-character alphanumeric unique identifier assigned by Amazon.com and its partners for product identification within the Amazon organization (summary from Wikipedia'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 documentation from Amazon for authoritative details. ASINs are most commonly encoded as text strings, but the asin property supports URL/URI as potential values too.
Can be used on: https://schema.org/Demand, https://schema.org/Offer, https://schema.org/Product
Implementation
static const asin = IriTerm.prevalidated('https://schema.org/asin');
