main entity of page
type: DatatypeProperty
range: URL
comment: Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details.

name
type: DatatypeProperty
range: Text
comment: The name of the item.

publishing principles
type: DatatypeProperty
domain: Creative Work
comment: 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. While such policies are most typically expressed in natural language, sometimes related information (e.g. indicating a funder) can be expressed using schema.org terminology.

schema version
type: DatatypeProperty
domain: Creative Work
range: Datatype
  union of: Text
  union of: URL
comment: 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.

temporal coverage
type: DatatypeProperty
domain: Creative Work
range: Datatype
  union of: DateTime
  union of: Text
  union of: URL
comment: 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.
