A [[Claim]] in Schema.org represents a specific, factually-oriented claim that could be the [[itemReviewed]] in a [[ClaimReview]]. The content of a claim can be summarized with the [[text]] property. Variations on well known claims can have their common identity indicated via [[sameAs]] links, and summarized with a [[name]]. Ideally, a [[Claim]] description includes enough contextual information to minimize the risk of ambiguity or inclarity. In practice, many claims are better understood in the context in which they appear or the interpretations provided by claim reviews.

  Beyond [[ClaimReview]], the Claim type can be associated with related creative works - for example a [[ScholarlyArticle]] or [[Question]] might be [[about]] some [[Claim]].

  At this time, Schema.org does not define any types of relationship between claims. This is a natural area for future exploration.

A cohort is a group of people who share a common characteristic or experience within a defined period (e.g., are born, leave school, lose their job, are exposed to a drug or a vaccine, etc.). The comparison group may be the general population from which the cohort is drawn, or it may be another cohort of persons thought to have had little or no exposure to the substance under investigation, but otherwise similar. Alternatively, subgroups within the cohort may be compared with each other.

Individual comic issues are serially published as
    	part of a larger series. For the sake of consistency, even one-shot issues
    	belong to a series comprised of a single issue. All comic issues can be

    	series to which the issue belongs; the issue number; and the variant
    	description of the issue (if any).

This is the equivalent of Atom's element as defined in Feed Paging and Archiving [RFC 5005](https://tools.ietf.org/html/rfc5005), For example (and as defined for Atom), when using data from a feed that represents a collection of items that varies over time (e.g. "Top Twenty Records") there is no need to have newer entries mixed in alongside older, obsolete entries. By marking this feed as a CompleteDataFeed, old entries can be safely discarded when the feed is refreshed, since we can assume the feed has provided descriptions for all current items.

A CreativeWorkSeries in schema.org is a group of related items, typically but not necessarily of the same kind. CreativeWorkSeries are usually organized into some order, often chronological. Unlike [[ItemList]] which is a general purpose data structure for lists of things, the emphasis with CreativeWorkSeries is on published materials (written e.g. books and periodicals, or media such as tv, radio and games).\n\nSpecific subtypes are available for describing [[TVSeries]], [[RadioSeries]], [[MovieSeries]], [[BookSeries]], [[Periodical]] and [[VideoGameSeries]]. In each case, the [[hasPart]] / [[isPartOf]] properties can be used to relate the CreativeWorkSeries to its parts. The general CreativeWorkSeries type serves largely just to organize these more specific and practical subtypes.\n\nIt is common for properties applicable to an item from the series to be usefully applied to the containing group. Schema.org attempts to anticipate some of these cases, but publishers should be free to apply properties of the series parts to the series as a whole wherever they seem appropriate.

A [[CriticReview]] is a more specialized form of Review written or published by a source that is recognized for its reviewing activities. These can include online columns, travel and food guides, TV and radio shows, blogs and other independent Web sites. [[CriticReview]]s are typically more in-depth and professionally written. For simpler, casually written user/visitor/viewer/customer reviews, it is more appropriate to use the [[UserReview]] type. Review aggregator sites such as Metacritic already separate out the site's user reviews from selected critic reviews that originate from third-party sources.

A media object that encodes this CreativeWork. This property is a synonym for associatedMedia.

Media type typically expressed using a MIME format (see [IANA site](http://www.iana.org/assignments/media-types/media-types.xhtml) and [MDN reference](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types)) 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.

The end date and time of the item (in [ISO 8601 date format](http://en.wikipedia.org/wiki/ISO_8601)).

A sub property of participant. The person/organization being supported.

An EndorsementRating is a rating that expresses some level of endorsement, for example inclusion in a "critic's pick" blog, a
"Like" or "+1" on a social network. It can be considered the [[result]] of an [[EndorseAction]] in which the [[object]] of the action is rated positively by
some [[agent]]. As is common elsewhere in schema.org, it is sometimes more useful to describe the results of such an action without explicitly describing the [[Action]].

An [[EndorsementRating]] may be part of a numeric scale or organized system, but this is not required: having an explicit type for indicating a positive,
endorsement rating is particularly useful in the absence of numeric scales as it helps consumers understand that the rating is broadly positive.

Properties that take Energy as values are of the form '&lt;Number&gt; &lt;Energy unit of measure&gt;'.

EnergyConsumptionDetails represents information related to the energy efficiency of a product that consumes energy. The information that can be provided is based on international regulations such as for example [EU directive 2017/1369](https://eur-lex.europa.eu/eli/reg/2017/1369/oj) for energy labeling and the [Energy labeling rule](https://www.ftc.gov/enforcement/rules/rulemaking-regulatory-reform-proceedings/energy-water-use-labeling-consumer) under the Energy Policy and Conservation Act (EPCA) in the US.

Enumerates energy efficiency levels (also known as "classes" or "ratings") and certifications that are part of several international energy efficiency standards.

An event happening at a certain time and location, such as a concert, lecture, or festival. Ticketing information may be added via the [[offers]] property. Repeated events may be structured as separate Event objects.

The eventAttendanceMode of an event indicates whether it occurs online, offline, or a mix.

An EventAttendanceModeEnumeration value is one of potentially several modes of organising an event, relating to whether it is online or offline.

The event has been cancelled. If the event has multiple startDate values, all are assumed to be cancelled. Either startDate or previousStartDate may be used to specify the event's cancelled date(s).

Indicates that the event was changed to allow online participation. See [[eventAttendanceMode]] for specifics of whether it is now fully or partially online.

The event has been postponed and no new date has been set. The event's previousStartDate should be set.

The event has been rescheduled. The event's previousStartDate should be set to the old date and the startDate should be set to the event's new date. (If the event has been rescheduled multiple times, the previousStartDate property may be repeated).

A reservation for an event like a concert, sporting event, or lecture.\n\nNote: This type is for information about actual reservations, e.g. in confirmation emails or HTML pages with individual confirmations of reservations. For offers of tickets, use [[Offer]].

Associates an [[Event]] with a [[Schedule]]. There are circumstances where it is preferable to share a schedule for a series of
      repeating events rather than data on the individual events themselves. For example, a website or application might prefer to publish a schedule for a weekly
      gym class rather than provide data on every event. A schedule could be processed by applications to add forthcoming events to a calendar. An [[Event]] that
      is associated with a [[Schedule]] using this property should not have [[startDate]] or [[endDate]] properties. These are instead defined within the associated
      [[Schedule]], this avoids any ambiguity for clients using the data. The property might have repeated values to specify different schedules, e.g. for different months
      or seasons.

The event is taking place or has taken place on the startDate as scheduled. Use of this value is optional, as it is assumed by default.

A series of [[Event]]s. Included events can relate with the series using the [[superEvent]] property.

An EventSeries is a collection of events that share some unifying characteristic. For example, "The Olympic Games" is a series, which
is repeated regularly. The "2012 London Olympics" can be presented both as an [[Event]] in the series "Olympic Games", and as an
[[EventSeries]] that included a number of sporting competitions as Events.

The nature of the association between the events in an [[EventSeries]] can vary, but typical examples could
include a thematic event series (e.g. topical meetups or classes), or a series of regular events that share a location, attendee group and/or organizers.

EventSeries has been defined as a kind of Event to make it easy for publishers to use it in an Event context without
worrying about which kinds of series are really event-like enough to call an Event. In general an EventSeries
may seem more Event-like when the period of time is compact and when aspects such as location are fixed, but
it may also sometimes prove useful to describe a longer-term series as an Event.
   
An eventStatus of an event represents its status; particularly useful when an event is cancelled or rescheduled.

EventStatusType is an enumeration type whose instances represent several states that an Event may be in.

Upcoming or past events associated with this place or organization.

Defines a [[Date]] or [[DateTime]] during which a scheduled [[Event]] will not take place. The property allows exceptions to
      a [[Schedule]] to be specified. If an exception is specified as a [[DateTime]] then only the event that would have started at that specific date and time
      should be excluded from the schedule. If an exception is specified as a [[Date]] then any event that is scheduled for that 24 hour period should be
      excluded from the schedule. This allows a whole day to be excluded from the schedule without having to itemise every scheduled event.

A Global Trade Item Number ([GTIN](https://www.gs1.org/standards/id-keys/gtin)). GTINs identify trade items, including products and services, using numeric identification codes. The [[gtin]] property generalizes the earlier [[gtin8]], [[gtin12]], [[gtin13]], and [[gtin14]] properties. The GS1 [digital link specifications](https://www.gs1.org/standards/Digital-Link/) express GTINs as URLs. A correct [[gtin]] value should be a valid GTIN, which means that it should be an all-numeric string of either 8, 12, 13 or 14 digits, or a "GS1 Digital Link" URL based on such a string. The numeric component should also have a [valid GS1 check digit](https://www.gs1.org/services/check-digit-calculator) and meet the other rules for valid GTINs. See also [GS1's GTIN Summary](http://www.gs1.org/barcodes/technical/idkeys/gtin) and [Wikipedia](https://en.wikipedia.org/wiki/Global_Trade_Item_Number) for more details. Left-padding of the gtin values is not required or encouraged.

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.

    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 size group (also known as "size type") for a product's size. Size groups are common in the fashion industry to define size segments and suggested audiences for wearable products. Multiple values can be combined, for example "men's big and tall", "petite maternity" or "regular"

Size related properties of a product, typically a size code ([[name]]) and optionally a [[sizeSystem]], [[sizeGroup]], and product measurements ([[hasMeasurement]]). In addition, the intended audience can be defined through [[suggestedAge]], [[suggestedGender]], and suggested body measurements ([[suggestedMeasurement]]).

The size system used to identify a product's size. Typically either a standard (for example, "GS1" or "ISO-EN13402"), country code (for example "US" or "JP"), or a measuring system (for example "Metric" or "Imperial").

Enumerates common size systems for different categories of products, for example "EN-13402" or "UK" for wearables or "Imperial" for screws.

The "spatial" property can be used in cases when more specific properties
(e.g. [[locationCreated]], [[spatialCoverage]], [[contentLocation]]) are not known to be appropriate.

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.

Indicates sections of a Web page that are particularly 'speakable' in the sense of being highlighted as being especially appropriate for text-to-speech conversion. Other sections of a page may also be usefully spoken in particular circumstances; the 'speakable' property serves to indicate the parts most likely to be generally useful for speech.

The *speakable* property can be repeated an arbitrary number of times, with three kinds of possible 'content-locator' values:

1.) *id-value* URL references - uses *id-value* of an element in the page being annotated. The simplest use of *speakable* has (potentially relative) URL values, referencing identified sections of the document concerned.

2.) CSS Selectors - addresses content in the annotated page, eg. via class attribute. Use the [[cssSelector]] property.

3.)  XPaths - addresses content via XPaths (assuming an XML view of the content). Use the [[xpath]] property.

For more sophisticated markup of speakable sections beyond simple ID references, either CSS selectors or XPath expressions to pick out document section(s) as speakable. For this
we define a supporting type, [[SpeakableSpecification]]  which is defined to be a possible value of the *speakable* property.
         
A SpeakableSpecification indicates (typically via [[xpath]] or [[cssSelector]]) sections of a document that are highlighted as particularly [[speakable]]. Instances of this type are expected to be used primarily as values of the [[speakable]] property.

A SpecialAnnouncement combines a simple date-stamped textual information update
      with contextualized Web links and other structured data.  It represents an information update made by a
      locally-oriented organization, for example schools, pharmacies, healthcare providers,  community groups, police,
      local government.

For work in progress guidelines on Coronavirus-related markup see [this doc](https://docs.google.com/document/d/14ikaGCKxo50rRM7nvKSlbUpjyIk2WMQd3IkB1lItlrM/edit#).

The motivating scenario for SpecialAnnouncement is the [Coronavirus pandemic](https://en.wikipedia.org/wiki/2019%E2%80%9320_coronavirus_pandemic), and the initial vocabulary is oriented to this urgent situation. Schema.org
expect to improve the markup iteratively as it is deployed and as feedback emerges from use. In addition to our
usual [Github entry](https://github.com/schemaorg/schemaorg/issues/2490), feedback comments can also be provided in [this document](https://docs.google.com/document/d/1fpdFFxk8s87CWwACs53SGkYv3aafSxz_DTtOQxMrBJQ/edit#).

While this schema is designed to communicate urgent crisis-related information, it is not the same as an emergency warning technology like [CAP](https://en.wikipedia.org/wiki/Common_Alerting_Protocol), although there may be overlaps. The intent is to cover
the kinds of everyday practical information being posted to existing websites during an emergency situation.

Several kinds of information can be provided:

We encourage the provision of "name", "text", "datePosted", "expires" (if appropriate), "category" and
"url" as a simple baseline. It is important to provide a value for "category" where possible, most ideally as a well known
URL from Wikipedia or Wikidata. In the case of the 2019-2020 Coronavirus pandemic, this should be "https://en.wikipedia.org/w/index.php?title=2019-20\_coronavirus\_pandemic" or "https://www.wikidata.org/wiki/Q81068910".

For many of the possible properties, values can either be simple links or an inline description, depending on whether a summary is available. For a link, provide just the URL of the appropriate page as the property's value. For an inline description, use a [[WebContent]] type, and provide the url as a property of that, alongside at least a simple "[[text]]" summary of the page. It is
unlikely that a single SpecialAnnouncement will need all of the possible properties simultaneously.

We expect that in many cases the page referenced might contain more specialized structured data, e.g. contact info, [[openingHours]], [[Event]], [[FAQPage]] etc. By linking to those pages from a [[SpecialAnnouncement]] you can help make it clearer that the events are related to the situation (e.g. Coronavirus) indicated by the [[category]] property of the [[SpecialAnnouncement]].

Many [[SpecialAnnouncement]]s will relate to particular regions and to identifiable local organizations. Use [[spatialCoverage]] for the region, and [[announcementLocation]] to indicate specific [[LocalBusiness]]es and [[CivicStructure]]s. If the announcement affects both a particular region and a specific location (for example, a library closure that serves an entire region), use both [[spatialCoverage]] and [[announcementLocation]].

The [[about]] property can be used to indicate entities that are the focus of the announcement. We now recommend using [[about]] only
for representing non-location entities (e.g. a [[Course]] or a [[RadioStation]]). For places, use [[announcementLocation]] and [[spatialCoverage]]. Consumers of this markup should be aware that the initial design encouraged the use of /about for locations too.

The basic content of [[SpecialAnnouncement]] is similar to that of an [RSS](https://en.wikipedia.org/wiki/RSS) or [Atom](https://en.wikipedia.org/wiki/Atom_(Web_standard)) feed. For publishers without such feeds, basic feed-like information can be shared by posting
[[SpecialAnnouncement]] updates in a page, e.g. using JSON-LD. For sites with Atom/RSS functionality, you can point to a feed
with the [[webFeed]] property. This can be a simple URL, or an inline [[DataFeed]] object, with [[encodingFormat]] providing
media type information e.g. "application/rss+xml" or "application/atom+xml".

Any special commitments associated with this job posting. Valid entries include VeteranCommit, MilitarySpouseCommit, etc.

Form of markup used. eg. [SSML](https://www.w3.org/TR/speech-synthesis11) or [IPA](https://www.wikidata.org/wiki/Property:P898).

The speed range of the vehicle. If the vehicle is powered by an engine, the upper limit of the speed range (indicated by [[maxValue]] should be the maximum speed achievable under regular conditions.\n\nTypical unit code(s): KMH for km/h, HM for mile per hour (0.447 04 m/s), KNT for knot\n\n*Note 1: Use [[minValue]] and [[maxValue]] to indicate the range. Typically, the minimal value is zero.\n* Note 2: There are many different ways of measuring the speed range. You can link to information about how the given value has been determined using the [[valueReference]] property.

An official rating for a lodging business or food establishment, e.g. from national associations or standards bodies. Use the author property to indicate the rating organization, e.g. as an Organization with name such as (e.g. HOTREC, DEHOGA, WHR, or Hotelstars).

The start date and time of the item (in [ISO 8601 date format](http://en.wikipedia.org/wiki/ISO_8601)).

The start time of the clip expressed as the number of seconds from the beginning of the work.

The startTime of something. For a reserved event or service (e.g. FoodEstablishmentReservation), the time that it is expected to start. For actions that span a period of time, when the action was performed. e.g. John wrote a book from *January* to December. For media, including audio and video, it's the time offset of the start of a clip within a larger file.\n\nNote that Event uses startDate/endDate instead of startTime/endTime, even when describing dates with times. This situation may be clarified in future revisions.

A StatisticalPopulation is a set of instances of a certain given type that satisfy some set of constraints. The property [[populationType]] is used to specify the type. Any property that can be used on instances of that type can appear on the statistical population. For example, a [[StatisticalPopulation]] representing all [[Person]]s with a [[homeLocation]] of East Podunk California, would be described by applying the appropriate [[homeLocation]] and [[populationType]] properties to a [[StatisticalPopulation]] item that stands for that set of people.
The properties [[numConstraints]] and [[constrainingProperty]] are used to specify which of the populations properties are used to specify the population. Note that the sense of "population" used here is the general sense of a statistical
population, and does not imply that the population consists of people. For example, a [[populationType]] of [[Event]] or [[NewsArticle]] could be used. See also [[Observation]], and the [data and datasets](/docs/data-and-datasets.html) overview for more details.

An event that this event is a part of. For example, a collection of individual music performances might each have a music festival as their superEvent.

Anatomical features that can be observed by sight (without dissection), including the form and proportions of the human body as well as surface landmarks that correspond to deeper subcutaneous structures. Superficial anatomy plays an important role in sports medicine, phlebotomy, and other medical specialties as underlying anatomical structures can be identified through surface palpation. For example, during back surgery, superficial anatomy can be used to palpate and count vertebrae to find the site of incision. Or in phlebotomy, superficial anatomy can be used to locate an underlying vein; for example, the median cubital vein can be located by palpating the borders of the cubital fossa (such as the epicondyles of the humerus) and then looking for the superficial signs of the vein, such as size, prominence, ability to refill after depression, and feel of surrounding tissue support. As another example, in a subluxation (dislocation) of the glenohumeral joint, the bony structure becomes pronounced with the deltoid muscle failing to cover the glenohumeral joint allowing the edges of the scapula to be superficially visible. Here, the superficial anatomy is the visible edges of the scapula, implying the underlying dislocation of the joint (the related anatomical structure).

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](https://en.wikipedia.org/wiki/ISO_8601#Time_intervals). In
