Breadcrumb List

A BreadcrumbList is an ItemList consisting of a chain of linked Web pages, typically described using at least their URL and their name, and typically ending with the current page.\n\nThe position property is used to reconstruct the order of the items in a BreadcrumbList. The convention is that a breadcrumb list has an itemListOrder of ItemListOrderAscending (lower values listed first), and that the first items in this list correspond to the "top" or beginning of the breadcrumb trail, e.g. with a site or section homepage. The specific values of 'position' are not assigned meaning for a BreadcrumbList, but they should be integers, e.g. beginning with '1' for the first item in the list.

Properties from ItemList

Property	Expected Type	description
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).
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	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. In RDFa syntax, it is better to use the native RDFa syntax - the 'typeof' attribute - for multiple types. Schema.org tools may have only weaker understanding of extra types, in particular those defined externally.
alternateName	Text	An alias for the item.
description	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.
image	URL ImageObject	An image of the item. This can be a URL or a fully described ImageObject.
instanceOf	Enumeration	Type to which this subject belongs. Use for membership in a value set (Enumeration), not inheritance. Example: K2 instanceOf mountain; volcano subClassOf mountain.
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	Event CreativeWork	A CreativeWork or Event about this Thing.
url	URL	URL of the item.
