Indicates a page documenting how licenses can be purchased or otherwise acquired, for the current item.
Indicates a page or other link involved in archival of a [CreativeWork](https://schema.org/CreativeWork). In the case of [MediaReview](https://schema.org/MediaReview), the items in a [MediaReviewItem](https://schema.org/MediaReviewItem) may often become inaccessible, but be archived by archival, journalistic, activist, or law enforcement organizations. In such cases, the referenced page may not directly publish the content.
The item being described is intended to assess the competency or learning outcome defined by the referenced term.
Conditions that affect the availability of, or method(s) of access to, an item. Typically used for real world items such as an [ArchiveComponent](https://schema.org/ArchiveComponent) held by an [ArchiveOrganization](https://schema.org/ArchiveOrganization). This property is not suitable for use as a general Web access control mechanism. It is expressed only in natural language.
For example "Available by appointment from the Reading Room" or "Accessible only from logged-in accounts ".
Text of a notice appropriate for describing the copyright aspects of this Creative Work, ideally indicating the owner of the copyright for the Work.
The country of origin of something, including products as well as creative works such as movie and TV content.
In the case of TV and movie, this would be the country of the principle offices of the production company or individual responsible for the movie. For other kinds of [CreativeWork](https://schema.org/CreativeWork) it is difficult to provide fully general guidance, and properties such as [contentLocation](https://schema.org/contentLocation) and [locationCreated](https://schema.org/locationCreated) may be more applicable.
In the case of products, the country of origin of the product. The exact interpretation of this may vary by context and product type, and cannot be fully enumerated here.
The status of a creative work in terms of its stage in a lifecycle. Example terms include Incomplete, Draft, Published, Obsolete. Some organizations define a set of terms for the stages of their publication lifecycle.
Text that can be used to credit person(s) and/or organization(s) associated with a published Creative Work.
An [EIDR](https://eidr.org/) (Entertainment Identifier Registry) [identifier](https://schema.org/identifier) representing a specific edit / edition for a work of film or television.
For example, the motion picture known as "Ghostbusters" whose [titleEIDR](https://schema.org/titleEIDR) is "10.5240/7EC7-228A-510A-053E-CBB8-J" has several edits, e.g. "10.5240/1F2A-E1C5-680A-14C6-E76B-I" and "10.5240/8A35-3BEE-6497-5D12-9E4F-3".
Since schema.org types like [Movie](https://schema.org/Movie) and [TVEpisode](https://schema.org/TVEpisode) can be used for both works and their multiple expressions, it is possible to use [titleEIDR](https://schema.org/titleEIDR) alone (for a general description), or alongside [editEIDR](https://schema.org/editEIDR) for a more edit-specific description.
The level in terms of progression through an educational or training context. Examples of educational levels include 'beginner', 'intermediate' or 'advanced', and formal sets of level indicators.
Used to indicate a specific claim contained, implied, translated or refined from the content of a [MediaObject](https://schema.org/MediaObject) or other [CreativeWork](https://schema.org/CreativeWork). The interpreting party can be indicated using [claimInterpreter](https://schema.org/claimInterpreter).
A maintainer of a [Dataset](https://schema.org/Dataset), software package ([SoftwareApplication](https://schema.org/SoftwareApplication)), or other [Project](https://schema.org/Project). A maintainer is a [Person](https://schema.org/Person) or [Organization](https://schema.org/Organization) that manages contributions to, and/or publication of, some (typically complex) artifact. It is common for distributions of software and data to be based on "upstream" sources. When [maintainer](https://schema.org/maintainer) is applied to a specific version of something e.g. a particular version or packaging of a [Dataset](https://schema.org/Dataset), it is always possible that the upstream source has a different maintainer. The [isBasedOn](https://schema.org/isBasedOn) property can be used to indicate such relationships between datasets to make the different maintenance roles clear. Similarly in the case of software, a package may have dedicated maintainers working on integration into software distributions such as Ubuntu, as well as upstream maintainers of the underlying work.
A pattern that something has, for example 'polka dot', 'striped', 'Canadian flag'. Values are typically expressed as text, although links to controlled value schemes are also supported.
A standardized size of a product or creative work, specified either through a simple textual string (for example 'XL', '32Wx34L'), a QuantitativeValue with a unitCode, or a comprehensive and structured [SizeSpecification](https://schema.org/SizeSpecification); in other cases, the [width](https://schema.org/width), [height](https://schema.org/height), [depth](https://schema.org/depth) and [weight](https://schema.org/weight) properties may be more applicable.
The item being described is intended to help a person learn the competency or learning outcome defined by the referenced term.
The schema.org [usageInfo](https://schema.org/usageInfo) property indicates further information about a [CreativeWork](https://schema.org/CreativeWork). This property is applicable both to works that are freely available and to those that require payment or other transactions. It can reference additional information, e.g. community expectations on preferred linking and citation conventions, as well as purchasing details. For something that can be commercially licensed, usageInfo can provide detailed, resource-specific information about licensing options.
This property can be used alongside the license property which indicates license(s) applicable to some piece of content. The usageInfo property can provide information about other licensing options, e.g. acquiring commercial usage rights for an image that is also available under non-commercial creative commons licenses.
