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".

SpecialAnnouncement schema code:
Note:Use this Schema.org based structured data generator tool to easily create SpecialAnnouncement schema. The properties are the description of your entity. You don't have to fill in all the properties on this page. Provide what is available and leave what is not. To learn more about each property in your schema type please check SpecialAnnouncement schema properties
Notes:To check if your code is eligible for featured snippets (rich snippets or rich results) test your code with the Rich Results Test tool to learn more about which schema are qualified for rich results check out Google’s search gallery.To validate your markup code, check your JSON-LD code with the Schema Markup Validator
Important Notes: to describe the relationship between your entities you must design a custom schema, this is where the 'creation of knowledge graph' is needed. For example: if you have a local business and you want to add a service catalogue, or if you have a recipe schema and you want to add a HowTo steps, or if you have a product and you want to add a FAQ about it, to learn more watch this semantic SEO workshop
