The name of the item.
An offer to provide this item—for example, an offer to sell a product, rent the DVD of a movie, perform a service, or give away tickets to an event. Use [businessFunction](https://schema.org/businessFunction) to indicate the kind of transaction offered, i.e. sell, lease, etc. This property can also be used to describe a [Demand](https://schema.org/Demand). While this property is listed as expected on a number of common types, it can be used in others. In that case, using a second type, such as Product or a subtype of Product, can clarify the nature of the offer.

Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.
Indicates the main image on the page.
The person or organization who produced the work (e.g. music album, movie, TV/radio series etc.).

A publication event associated with the item.
The publisher of the article in question.
The publishing division which published the comic.
The publishingPrinciples property indicates (typically via [URL](https://schema.org/URL)) a document describing the editorial principles of an [Organization](https://schema.org/Organization) (or individual, e.g. a [Person](https://schema.org/Person) writing a blog) that relate to their activities as a publisher, e.g. ethics or diversity policies. When applied to a [CreativeWork](https://schema.org/CreativeWork) (e.g. [NewsArticle](https://schema.org/NewsArticle)) the principles are those of the party primarily responsible for the creation of the [CreativeWork](https://schema.org/CreativeWork).
While such policies are most typically expressed in natural language, sometimes related information (e.g. indicating a [funder](https://schema.org/funder)) can be expressed using schema.org terminology.
The Event where the CreativeWork was recorded. The CreativeWork may capture all or part of the event.
A link related to this web page, for example to other related web pages.
The place and time the release was issued, expressed as a PublicationEvent.
A review of the item.
People or organizations that have reviewed the content on this web page for accuracy and/or completeness.
Review of the item.
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.
Indicates (by URL or string) a particular version of a schema used in some CreativeWork. This property was created primarily to indicate the use of a specific schema.org release, e.g. `10.0` as a simple string, or more explicitly via URL, `https://schema.org/docs/releases.html#v10.0`. There may be situations in which other schemas might usefully be referenced this way, e.g. `http://dublincore.org/specifications/dublin-core/dces/1999-07-02/` but this has not been carefully explored in the community.
Indicates the date on which the current structured data was generated / published. Typically used alongside [sdPublisher](https://schema.org/sdPublisher).
A license document that applies to this structured data, typically indicated by URL.
Indicates the party responsible for generating and publishing the current structured data markup, typically in cases where the structured data is derived automatically from existing published content but published on a different site. For example, student projects and open data initiatives often re-publish existing content with more explicitly structured metadata. The [sdPublisher](https://schema.org/sdPublisher) property helps make such practices more explicit.
One of the more significant URLs on the page. Typically, these are the non-navigation links that are clicked on the most.
The most significant URLs on the page. Typically, these are the non-navigation links that are clicked on the most.
The Organization on whose behalf the creator was working.
The "spatial" property can be used in cases when more specific properties (e.g. [locationCreated](https://schema.org/locationCreated), [spatialCoverage](https://schema.org/spatialCoverage), [contentLocation](https://schema.org/contentLocation)) are not known to be appropriate.
The spatialCoverage of a CreativeWork indicates the place(s) which are the focus of the content. It is a subproperty of
contentLocation intended primarily for more technical and detailed materials. For example with a Dataset, it indicates
areas that the dataset describes: a dataset of New York weather would have spatialCoverage which was the place: the state of New York.
Indicates sections of a Web page that are particularly 'speakable' in the sense of being highlighted as being especially appropriate for text-to-speech conversion. Other sections of a page may also be usefully spoken in particular circumstances; the 'speakable' property serves to indicate the parts most likely to be generally useful for speech.
The *speakable* property can be repeated an arbitrary number of times, with three kinds of possible 'content-locator' values:
1.) *id-value* URL references - uses *id-value* of an element in the page being annotated. The simplest use of *speakable* has (potentially relative) URL values, referencing identified sections of the document concerned.
2.) CSS Selectors - addresses content in the annotated page, e.g. via class attribute. Use the [cssSelector](https://schema.org/cssSelector) property.
3.) XPaths - addresses content via XPaths (assuming an XML view of the content). Use the [xpath](https://schema.org/xpath) property.
For more sophisticated markup of speakable sections beyond simple ID references, either CSS selectors or XPath expressions to pick out document section(s) as speakable. For this we define a supporting type, [SpeakableSpecification](https://schema.org/SpeakableSpecification) which is defined to be a possible value of the *speakable* property.
One of the domain specialities to which this web page's content applies.
A person or organization that supports a thing through a pledge, promise, or financial contribution. E.g. a sponsor of a Medical Study or a corporate sponsor of an event.
A CreativeWork or Event about this Thing.
The "temporal" property can be used in cases where more specific properties (e.g. [temporalCoverage](https://schema.org/temporalCoverage), [dateCreated](https://schema.org/dateCreated), [dateModified](https://schema.org/dateModified), [datePublished](https://schema.org/datePublished)) are not known to be appropriate.
The temporalCoverage of a CreativeWork indicates the period that the content applies to, i.e. that it describes, either as a DateTime or as a textual string indicating a time period in [ISO 8601 time interval format](https://en.wikipedia.org/wiki/ISO_8601#Time_intervals). In the case of a Dataset it will typically indicate the relevant time period in a precise notation (e.g. for a 2011 census dataset, the year 2011 would be written "2011/2012"). Other forms of content, e.g. ScholarlyArticle, Book, TVSeries or TVEpisode, may indicate their temporalCoverage in broader terms - textually or via well-known URL. Written works such as books may sometimes have precise temporal coverage too, e.g. a work set in 1939 - 1945 can be indicated in ISO 8601 interval format format via "1939/1945".
Open-ended date ranges can be written with ".." in place of the end date. For example, "2015-11/.." indicates a range beginning in November 2015 and with no specified final date. This is tentative and might be updated in future when ISO 8601 is officially updated.
