Properties from ItemList

Property Expected Type Description
aggregateElement Thing Indicates a prototype of the elements in the list that is used to hold aggregate information (ratings, offers, etc.).
itemListElement ListItem, Thing, Text For itemListElement values, you can use simple strings (e.g. "Peter", "Paul", "Mary"), existing entities, or use ListItem.

Text values are best if the elements in the list are plain strings. Existing entities are best for a simple, unordered list of existing things in your data. ListItem is used with ordered lists when you want to provide additional context about the element in that list or when the same item might be in different places in different lists.

Note: The order of elements in your mark-up is not sufficient for indicating the order or elements. Use ListItem with a 'position' property in such cases.
itemListOrder Text, ItemListOrderType Type of ordering (e.g. Ascending, Descending, Unordered).
numberOfItems Integer The number of items in an ItemList. Note that some descriptions might not fully describe all items in a list (e.g., multi-page pagination); in such cases, the numberOfItems would be for the entire list.

Properties from Thing

Property Expected Type Description
additionalType Text, URL An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org style guide.
alternateName Text An alias for the item.
description TextObject, Text A description of the item.
disambiguatingDescription Text A sub property of description. A short description of the item used to disambiguate from other, similar items. Information from other properties (in particular, name) may be necessary for the description to be useful for disambiguation.
identifier PropertyValue, URL, Text The identifier property represents any kind of identifier for any kind of Thing, such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See background notes for more details.
image ImageObject, URL An image of the item. This can be a URL or a fully described ImageObject.
mainEntityOfPage URL, CreativeWork Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details.
name Text The name of the item.
potentialAction Action Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.
sameAs URL URL of a reference Web page that unambiguously indicates the item's identity. E.g. the URL of the item's Wikipedia page, Wikidata entry, or official website.
subjectOf CreativeWork, Event A CreativeWork or Event about this Thing.
url URL URL of the item.

Instances of ItemList may appear as a value for the following properties

Property On Types Description
positiveNotes Product, Review Provides positive considerations regarding something, for example product highlights or (alongside negativeNotes) pro/con lists for reviews. In the case of a Review, the property describes the itemReviewed from the perspective of the review; in the case of a Product, the product itself is being described. The property values can be expressed either as unstructured text (repeated as necessary), or if ordered, as a list (in which case the most positive is at the beginning of the list).
