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. 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.orgexpect to improve the markup iteratively as it is deployed and as feedback emerges from use. In addition to ourusual [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 coverthe 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) and"url" as a simple baseline. It is important to provide a value for "category" where possible, most ideally as a well knownURL 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](http://schema.org/WebContent) type, and provide the url as a property of that, alongside at least a simple "[text](http://schema.org/text)" summary of the page. It isunlikely that a single SpecialAnnouncement will need all of the possible properties simultaneously. More options may be addedlater if We expect that in many cases the page referenced might contain more specialized structured data, e.g. contact info, [openingHours](http://schema.org/openingHours), [Event](http://schema.org/Event), [FAQPage](http://schema.org/FAQPage) etc. By linking to those pages from a [SpecialAnnouncement](http://schema.org/SpecialAnnouncement) you can help make it clearer that the events are related to the situation(e.g. Coronavirus) indicated by the [category](http://schema.org/category) property of the [SpecialAnnouncement](http://schema.org/SpecialAnnouncement). The basic content of [SpecialAnnouncement](http://schema.org/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](http://schema.org/SpecialAnnouncement) updates in a page, e.g. using JSON-LD. For sites with Atom/RSS functionality, you can point to a feedwith the [webFeed](http://schema.org/webFeed) property. This can be a simple URL, or an inline [DataFeed](http://schema.org/DataFeed) object, with [encodingFormat](http://schema.org/encodingFormat) providingmedia type information e.g. "application/rss+xml" or "application/atom+xml". For an announcement that is about a place, you can use [about](http://schema.org/about) (or [mainEntity](http://schema.org/mainEntity)) to make that relationship explicit.For example, the announcement could be "about" a new [CovidTestingFacility](http://schema.org/CovidTestingFacility), and provide contact information, [location](http://schema.org/location), [geo](http://schema.org/geo),[openingHours](http://schema.org/openingHours) etc.
