Special Announcement

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.
The motivating scenario for SpecialAnnouncement is the 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, feedback comments can also be provided in this document.
While this schema is designed to communicate urgent crisis-related information, it is not the same as an emergency warning technology like CAP, 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 SpecialAnnouncements will relate to particular regions and to identifiable local organizations. Use spatialCoverage for the region, and announcementLocation to indicate specific LocalBusinesses and CivicStructures. 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 or Atom) 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".

maintainer	Person Organization	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.

materialExtent	QuantitativeValue 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 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.
pattern	DefinedTerm 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	Text Integer	The position of an item in a series or sequence of items.
producer	Organization Person	The person or organization who produced the work (e.g. music album, movie, TV/radio series etc.).

publication	PublicationEvent	A publication event associated with the item.
publisher	Organization Person	The publisher of the creative work.
publisherImprint	Organization	The publishing division which published the comic.
publishingPrinciples	CreativeWork 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.
releasedEvent	PublicationEvent	The place and time the release was issued, expressed as a PublicationEvent.
requiredMaxAge	Integer	Audiences defined by a person's maximum age.

review	Review	A review of the item.
reviews	Review	Review of the item.
schemaVersion	URL Text	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/knowledge-graph/docs/releases#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 URL	A license document that applies to this structured data, typically indicated by URL.
sdPublisher	Organization 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 QuantitativeValue Text SizeSpecification	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 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 Text	The item being described is intended to help a person learn the competency or learning outcome defined by the referenced term.
temporal	DateTime 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	URL Text DateTime	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.
text	Text	The textual content of this CreativeWork.
thumbnailUrl	URL	A thumbnail image relevant to the Thing.
timeRequired	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'.
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”.
translator	Organization 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	URL CreativeWork	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 Text	The version of the CreativeWork embodied by a specified resource.
video	VideoObject Clip	An embedded video object.
workExample	CreativeWork	Example/instance/realization/derivation of the concept of this creative work. E.g. the paperback edition, first edition, or e-book.
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.

Properties from Thing

Property	Expected Type	description
additionalType	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.

editEIDR	URL Text	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.

maintainer	Person Organization	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.

materialExtent	QuantitativeValue 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 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.
pattern	DefinedTerm 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	Text Integer	The position of an item in a series or sequence of items.
producer	Organization Person	The person or organization who produced the work (e.g. music album, movie, TV/radio series etc.).

publisherImprint	Organization	The publishing division which published the comic.
publishingPrinciples	CreativeWork 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.
releasedEvent	PublicationEvent	The place and time the release was issued, expressed as a PublicationEvent.
requiredMaxAge	Integer	Audiences defined by a person's maximum age.

review	Review	A review of the item.
reviews	Review	Review of the item.
schemaVersion	URL Text	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/knowledge-graph/docs/releases#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 URL	A license document that applies to this structured data, typically indicated by URL.
sdPublisher	Organization 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 QuantitativeValue Text SizeSpecification	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 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 Text	The item being described is intended to help a person learn the competency or learning outcome defined by the referenced term.
temporal	DateTime 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	URL Text DateTime	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.
text	Text	The textual content of this CreativeWork.
thumbnailUrl	URL	A thumbnail image relevant to the Thing.
timeRequired	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'.
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”.
translator	Organization 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	URL CreativeWork	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 Text	The version of the CreativeWork embodied by a specified resource.
video	VideoObject Clip	An embedded video object.
workExample	CreativeWork	Example/instance/realization/derivation of the concept of this creative work. E.g. the paperback edition, first edition, or e-book.
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.

Properties from Thing

Property	Expected Type	description
additionalType	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.
