The position of an item in a series or sequence of items.

Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.

A publication event associated with the item.

The publisher of the article in question.

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 place and time the release was issued, expressed as a PublicationEvent.

A review of the item.

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.

The Organization on whose behalf the creator was working.

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.

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.

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.

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](https://schema.org/docs/styleguide.html).
