PropertyExpected TypeDescription
Properties from Thing
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  or
Text  or
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 for more details.
image ImageObject  or
URL 
An image of the item. This can be a URL or a fully described ImageObject.
mainEntityOfPage CreativeWork  or
URL 
Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details.
Inverse property: mainEntity.
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.
url URL URL of the item.


Instances of Duration may appear as values for the following properties

PropertyOn TypesDescription
billingPeriod Invoice The time interval used to compute the invoice.
cookTime Recipe The time it takes to actually cook the dish, in ISO 8601 duration format.
duration Audiobook  or
Event  or
MediaObject  or
Movie  or
MusicRecording  or
MusicRelease 
The duration of the item (movie, audio recording, event, etc.) in ISO 8601 date format.
estimatedFlightDuration Flight The estimated time the flight will take.
eventSchedule Schedule Associates an Event with a Schedule. There are circumstances where it is preferable to share a schedule for a series of repeating events rather than data on the individual events themselves. For example, a website or application might prefer to publish a schedule for a weekly gym class rather than provide data on every event. A schedule could be processed by applications to add forthcoming events to a calendar. An Event that is associated with a Schedule using this property should not have startDate or endDate properties. These are instead defined within the associated Schedule, this avoids any ambiguity for clients using the data. The propery might have repeated values to specify different schedules, e.g. for different months or seasons.
