Explicitly define properties which are arrays / collections. #3371

If such a distinction were specified, I expect it would be a property of each Property, but schema.org itself does not define such a property. OWL 2 defines owl:FunctionalProperty and owl:maxCardinality but those are not referenced in https://github.com/schemaorg/schemaorg/blob/main/data/releases/22.0/schemaorg.owl. |

The OWL route does not seem feasible to me, because (1) schema.org by and large uses its own base formalism and not plain RDF-S/OWL etc. (despite some overlap) and (2) it will likely be hard to use OWL reasoning for data quality checks in a production environment. |

IMO, the cleanest and most state-of-the-art way of adding this feature (aka "cardinality constraints") to schema.org would be providing a SHACL shape definition that either specifies the entire schema.org vocabulary in an alternative formalism, or an isolated "schema.org data quality" SHACL shape. For examples, see e.g. here. @danbri - maybe you could comment on plans re adding SHACL shapes for data quality rules in schema.org. |

Is there anyway to determine if a property can be an array / collection of children or a single value?
Example: https://schema.org/ItemList
The itemListElement property example is an array, but the numberOfItems property is an
Integer.{ "@context": "https://schema.org", "@type": "ItemList", "url": "http://multivarki.ru?filters%5Bprice%5D%5BLTE%5D=39600", "numberOfItems": "315", "itemListElement": [ { "@type": "Product", "image": "http://img01.multivarki.ru.ru/c9/f1/a5fe6642-18d0-47ad-b038-6fca20f1c923.jpeg", "url": "http://multivarki.ru/brand_502/", "name": "Brand 502", "offers": { "@type": "Offer", "priceCurrency": "RUB", "price": "4399.00" } }, { "@type": "Product", "name": "..." } ] }Beta Was this translation helpful?
