Properties from CreativeWork
about Thing The subject matter of an object.
Inverse property: subjectOf
abstract Text An abstract is a short description that summarizes a CreativeWork.

URL		 Indicates a page documenting how licenses can be purchased or otherwise acquired, for the current item.
aggregateRating AggregateRating The overall rating, based on a collection of reviews or ratings, of the item.
alternativeHeadline Text A secondary title of the CreativeWork.
archivedAt URL  or
WebPage		 Indicates a page or other link involved in archival of a CreativeWork. In the case of MediaReview, the items in a 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.
assesses DefinedTerm  or
Text		 The item being described is intended to assess the competency or learning outcome defined by the referenced term.
associatedMedia MediaObject A media object that encodes this CreativeWork. This property is a synonym for encoding.
audience Audience An intended audience, i.e. a group for whom something was created. Supersedes serviceAudience.
audio AudioObject  or
Clip  or
MusicRecording		 An embedded audio object.
author Organization  or
Person		 The author of this content or rating. Please note that author is special in that HTML 5 provides a special mechanism for indicating authorship via the rel tag. That is equivalent to this and may be used interchangeably.
award Text An award won by or for this item. Supersedes awards.
character Person Fictional person connected with a creative work.
citation CreativeWork  or
Text		 A citation or reference to another creative work, such as another publication, web page, scholarly article, etc.
comment Comment Comments, typically from users.
commentCount Integer The number of comments this CreativeWork (e.g. Article, Question or Answer) has received. This is most applicable to works published in Web sites with commenting system; additional comments may exist elsewhere.
conditionsOfAccess Text Conditions that affect the availability of, or method(s) of access to, an item. Typically used for real world items such as an ArchiveComponent held by an 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 ".
contentLocation Place The location depicted or described in the content. For example, the location in a photograph or painting.
contentRating Rating  or

copyrightNotice Text Text of a notice appropriate for describing the copyright aspects of this Creative Work, ideally indicating the owner of the copyright for the Work.
copyrightYear Number The year during which the claimed copyright for the CreativeWork was first asserted.
correction CorrectionComment  or
Text  or
URL		 Indicates a correction to a CreativeWork, either via a CorrectionComment, textually or in another document.
countryOfOrigin Country 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 it is difficult to provide fully general guidance, and properties such as contentLocation and 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.
creativeWorkStatus DefinedTerm  or
Text		 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.
creator Organization  or
Person		 The creator/author of this CreativeWork. This is the same as the Author property for CreativeWork.
creditText Text Text that can be used to credit person(s) and/or organization(s) associated with a published Creative Work.
dateCreated Date  or
DateTime		 The date on which the CreativeWork was created or the item was added to a DataFeed.
dateModified Date  or
DateTime		 The date on which the CreativeWork was most recently modified or when the item's entry was modified within a DataFeed.

displayLocation Place The location at which an item can be viewed or experienced in-person.
editEIDR Text  or
URL		 An EIDR (Entertainment Identifier Registry) identifier representing a specific edit / edition for a work of film or television.

For example, the motion picture known as "Ghostbusters" whose 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 and TVEpisode can be used for both works and their multiple expressions, it is possible to use titleEIDR alone (for a general description), or alongside editEIDR for a more edit-specific description.
editor Person Specifies the Person who edited the CreativeWork.
educationalAlignment AlignmentObject An alignment to an established educational framework.

This property should not be used where the nature of the alignment can be described using a simple property, for example to express that a resource teaches or assesses a competency.
educationalLevel DefinedTerm  or

encoding MediaObject A media object that encodes this CreativeWork. This property is a synonym for associatedMedia. Supersedes encodings.
Inverse property: encodesCreativeWork
encodingFormat Text  or
URL		 Media type typically expressed using a MIME format (see IANA site and MDN reference), e.g. application/zip for a SoftwareApplication binary, audio/mpeg for .mp3 etc.

In cases where a CreativeWork has several media type representations, encoding can be used to indicate each MediaObject alongside particular encodingFormat information.

Unregistered or niche encoding and file formats can be indicated instead via the most appropriate URL, e.g. defining Web page or a Wikipedia/Wikidata entry. Supersedes fileFormat.
exampleOfWork CreativeWork A creative work that this work is an example/instance/realization/derivation of.
Inverse property: workExample
expires Date  or
DateTime		 Date the content expires and is no longer useful or available. For example a VideoObject or NewsArticle whose availability or relevance is time-limited, a ClaimReview fact check whose publisher wants to indicate that it may no longer be relevant (or helpful to highlight) after some date, or a Certification the validity has expired.
funder Organization  or
Person		 A person or organization that supports (sponsors) something through some kind of financial contribution.

Inverse property: hasPart
keywords DefinedTerm  or
Text  or
URL		 Keywords or tags used to describe some item. Multiple textual entries in a keywords list are typically delimited by commas, or by repeating the property.
learningResourceType DefinedTerm  or

mainEntity Thing Indicates the primary entity described in some page or other CreativeWork.
Inverse property: mainEntityOfPage
maintainer Organization  or
Person		 A maintainer of a Dataset, software package (SoftwareApplication), or other Project. A maintainer is a Person or 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 is applied to a specific version of something e.g. a particular version or packaging of a Dataset, it is always possible that the upstream source has a different maintainer. The 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.
material Product  or
Text  or
URL		 A material that something is made from, e.g. leather, wool, cotton, paper.
materialExtent QuantitativeValue  or
Text		 The quantity of the materials being described or an expression of the physical space they occupy.
mentions Thing Indicates that the CreativeWork contains a reference to, but is not necessarily about a concept.
offers Demand  or
Offer		 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 to indicate the kind of transaction offered, i.e. sell, lease, etc. This property can also be used to describe a 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.
Inverse property: itemOffered
pattern DefinedTerm  or
Text		 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.
position Integer  or
Text		 The position of an item in a series or sequence of items.
producer Organization  or
Person		 The person or organization who produced the work (e.g. music album, movie, TV/radio series etc.).
provider Organization  or
Person		 The service provider, service operator, or service performer; the goods producer. Another party (a seller) may offer those services or goods on behalf of the provider. A provider may also serve as the seller. Supersedes carrier.
publication PublicationEvent A publication event associated with the item.
publisher Organization  or
Person		 The publisher of the article in question.
publisherImprint Organization The publishing division which published the comic.
publishingPrinciples CreativeWork  or
URL		 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.
recordedAt Event The Event where the CreativeWork was recorded. The CreativeWork may capture all or part of the event.
Inverse property: recordedIn
releasedEvent PublicationEvent The place and time the release was issued, expressed as a PublicationEvent.
review Review A review of the item. Supersedes reviews.
schemaVersion Text  or
URL		 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.
sdDatePublished Date Indicates the date on which the current structured data was generated / published. Typically used alongside sdPublisher.
sdLicense CreativeWork  or
URL		 A license document that applies to this structured data, typically indicated by URL.
sdPublisher Organization  or
Person		 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 property helps make such practices more explicit.
size DefinedTerm  or
QuantitativeValue  or
SizeSpecification  or
Text		 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; in other cases, the width, height, depth and weight properties may be more applicable.
sourceOrganization Organization The Organization on whose behalf the creator was working.
spatial Place The "spatial" property can be used in cases when more specific properties (e.g. locationCreated, spatialCoverage, contentLocation) are not known to be appropriate.
spatialCoverage 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.
sponsor Organization  or
Person		 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.
teaches DefinedTerm  or
Text		 The item being described is intended to help a person learn the competency or learning outcome defined by the referenced term.
temporal DateTime  or
Text		 The "temporal" property can be used in cases where more specific properties (e.g. temporalCoverage, dateCreated, dateModified, datePublished) are not known to be appropriate.
temporalCoverage DateTime  or
Text  or
URL		 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 Text The textual content of this CreativeWork.
thumbnail ImageObject Thumbnail image for an image or video.
thumbnailUrl URL A thumbnail image relevant to the Thing.
timeRequired Duration Approximate or typical time it usually takes to work with or through the content of this work for the typical or target audience.
translationOfWork CreativeWork The work that this work has been translated from. E.g. 物种起源 is a translationOf “On the Origin of Species”.
Inverse property: workTranslation
translator Organization  or
Person		 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.
typicalAgeRange Text The typical expected age range, e.g. '7-9', '11-'.
usageInfo CreativeWork  or
URL		 The schema.org usageInfo property indicates further information about a 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.
version Number  or
Text		 The version of the CreativeWork embodied by a specified resource.
video Clip  or
VideoObject		 An embedded video object.
wordCount Integer The number of words in the text of the CreativeWork such as an Article, Book, etc.
workExample CreativeWork Example/instance/realization/derivation of the concept of this creative work. E.g. the paperback edition, first edition, or e-book.
Inverse property: exampleOfWork
workTranslation CreativeWork A work that is a translation of the content of this work. E.g. 西遊記 has an English workTranslation “Journey to the West”, a German workTranslation “Monkeys Pilgerfahrt” and a Vietnamese translation Tây du ký bình khảo.
Inverse property: translationOfWork
Properties from Thing
additionalType Text  or
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. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. 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.
alternateName Text An alias for the item.
description Text  or
TextObject		 A description of the item.
disambiguatingDescription 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.
identifier PropertyValue  or
Text  or
URL		 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.
image ImageObject  or
URL		 An image of the item. This can be a URL or a fully described ImageObject.
mainEntityOfPage CreativeWork  or
URL		 Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details.
Inverse property: mainEntity
name Text The name of the item.
owner Organization  or
Person		 A person or organization who owns this Thing.
Inverse property: owns
potentialAction Action Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.
sameAs URL 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.
subjectOf CreativeWork  or
Event		 A CreativeWork or Event about this Thing.
Inverse property: about
url URL URL of the item.

    <h2>Abstract</h2>
    <p>When Schema.org arrived on the scene I thought we might have arrived at the point where library metadata could finally blossom; adding value outside of library systems to help library curated resources become first class citizens, and hence results, in the global web we all inhabit.

    <h2>Introduction</h2>
    <p>I have been rattling around the library systems industry/sector for nigh on thirty years, with metadata always being somewhere near the core of my thoughts. From that time as a programmer wrestling with the new to me ‘so-called’ standard <abbr title="Machine-Readable Cataloging">MARC</abbr>; reacting to meet the challenges of the burgeoning web; through the elephantine gestation of <abbr title="Resource Description & Access">RDA</abbr>; several experiments with linked library data; and the false starts of <abbr title="Bibliographic Framework">BIBFRAME</abbr>, it has consistently never scaled to the real world beyond the library walls and firewall.</p>
