ItemList — Schema.org Type, Hierarchy & Properties

Source: Schema.org v30.1 offline vocabulary. Official ItemList definition.

What is ItemList?

A list of items of any sort—for example, Top 10 Movies About Weathermen, or Top 100 Party Songs. Not to be confused with HTML lists, which are often used only for formatting.

This minimal example only identifies a Schema.org type. It is not a complete entity, a Google rich-result test, or a claim about a real business.

Full parent hierarchy

Each chain starts at a root type. Multiple paths are shown when Schema.org defines more than one parent. For very complex types, up to 256 paths are displayed; consult the official definition for the full graph.

Properties that accept ItemList values (10)

Property	On types	Description
acceptedAnswer	Question	The answer(s) that has been accepted as best, typically on a Question/Answer site. Sites vary in their selection mechanisms, e.g. drawing on community opinion and/or the view of the Question author.
accessModeSufficient	CreativeWork	A list of single or combined access modes that are sufficient to understand all the intellectual content of a resource, including any adaptations. Values should be drawn from the [approved vocabulary](https://www.w3.org/2021/a11y-discov-vocab/latest/#accessModeSufficient-vocabulary).
itinerary	Trip	Destination(s) ( [[Place]] ) that make up a trip. For a trip where destination order is important use [[ItemList]] to specify that order (see examples).
negativeNotes	Product or Review	Provides negative considerations regarding something, most typically in pro/con lists for reviews (alongside [[positiveNotes]]). For symmetry 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. Since product descriptions tend to emphasise positive claims, it may be relatively unusual to find [[negativeNotes]] used in this way. Nevertheless for the sake of symmetry, [[negativeNotes]] can be used on [[Product]]. The property values can be expressed either as unstructured text (repeated as necessary), or if ordered, as a list (in which case the most negative is at the beginning of the list).
positiveNotes	Product or 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).
recipeIngredient	Recipe	An ingredient or ordered list of ingredients and potentially quantities used in the recipe, e.g. 1 cup of sugar, flour or garlic. The ingredients can be represented as free text or more structured values.
recipeInstructions	Recipe	A step in making the recipe, in the form of a single item (document, video, etc.) or an ordered list with HowToStep and/or HowToSection items.
steps	HowTo or HowToSection	A single step item (as HowToStep, text, document, video, etc.) or a HowToSection (originally misnamed 'steps'; 'step' is preferred).
suggestedAnswer	Question	An answer (possibly one of several, possibly incorrect) to a Question, e.g. on a Question/Answer site.
track	MusicGroup or MusicPlaylist	A music recording (track)—usually a single song. If an ItemList is given, the list should contain items of type MusicRecording.

Properties usable on ItemList (17)

This list includes properties whose domainIncludes names ItemList or one of its ancestors. DomainIncludes is advisory; it is not an exhaustive set of permitted properties.

Property	Expected value types	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 <a href="https://schema.org/docs/styleguide.html">style guide</a>.
aggregateElement	Thing	Indicates a prototype of the elements in the list that is used to hold aggregate information (ratings, offers, etc.).
alternateName	Text	An alias for the item.
description	Text, TextObject	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, Text, URL	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](/docs/datamodel.html#identifierBg) for more details.
image	ImageObject, URL	An image of the item. This can be a [[URL]] or a fully described [[ImageObject]].
itemListElement	ListItem, Text, Thing	For itemListElement values, you can use simple strings (e.g. "Peter", "Paul", "Mary"), existing entities, or use ListItem.\n\nText 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.\n\nNote: 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	ItemListOrderType, Text	Type of ordering (e.g. Ascending, Descending, Unordered).
mainEntityOfPage	CreativeWork, URL	Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See [background notes](/docs/datamodel.html#mainEntityBackground) for details.
name	Text	The name of the item.
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.
owner	Organization, Person	A person or organization who owns this Thing.
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.
