The publishingPrinciples property indicates (typically via URL) a document describing the editorial principles of an Organization(or individual e.g. a Person writing a blog) that relate to their activities as a publisher, e.g. ethics or diversity policies. When applied to a CreativeWork (e.g. NewsArticle) the principles are those of the party primarily responsible for the creation of the CreativeWork.

Date Indicates the date on which the current structured data was generated / published. Typically used alongside 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 sdPublisherproperty helps make such practices more explicit.
Organization The Organization on whose behalf the creator was working.
Place The “spatial” property can be used in cases when more specific properties (e.g. locationCreated, spatialCoverage, contentLocation) are not known to be appropriate.
Place 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 “temporal” property can be used in cases where more specific properties (e.g. temporalCoverage, dateCreated, dateModified, 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. 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. Supersedes datasetTimeInterval.
Text The textual content of this CreativeWork.
URL A thumbnail image relevant to the Thing.
Duration Approximate or typical time it takes to work with or through this learning resource for the typical intended target audience, e.g. ‘PT30M’, ‘PT1H25M’.

Inverse property: workTranslation.
Organization or person who adapts a creative work to different languages, regional differences and technical requirements of a target market, or that translates during some event.
Text The typical expected age range, e.g. ‘7-9’, ’11-‘.

An embedded video object.
CreativeWork Example/instance/realization/derivation of the concept of this creative work. eg. The paperback edition, first edition, or eBook.
Inverse property: exampleOfWork.

Inverse property: translationOfWork.
Properties from Thing
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.
Text An alias for the item.

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.
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.
