| rdfs:comment | A SpecialAnnouncement combines a simple date-stamped textual information update\n with contextualized Web links and other structured data. It represents an information update made by a\n locally-oriented organization, for example schools, pharmacies, healthcare providers, community groups, police,\n local government.\n\nFor work in progress guidelines on Coronavirus-related markup see [this doc](https://docs.google.com/document/d/14ikaGCKxo50rRM7nvKSlbUpjyIk2WMQd3IkB1lItlrM/edit#).\n\nThe 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\nexpect to improve the markup iteratively as it is deployed and as feedback emerges from use. In addition to our\nusual [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#).\n\n\nWhile 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\nthe kinds of everyday practical information being posted to existing websites during an emergency situation.\n\nSeveral kinds of information can be provided:\n\nWe encourage the provision of \“name\”, \“text\”, \“datePosted\”, \“expires\” (if appropriate), \“category\” and\n\“url\” as a simple baseline. It is important to provide a value for \“category\” where possible, most ideally as a well known\nURL 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\“.\n\nFor 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\nunlikely that a single SpecialAnnouncement will need all of the possible properties simultaneously.\n\nWe 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`.\n\nMany `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`.\n\nThe `about` property can be used to indicate entities that are the focus of the announcement. We now recommend using `about` only\nfor 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.\n\nThe 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\n`SpecialAnnouncement` updates in a page, e.g. using JSON-LD. For sites with Atom/RSS functionality, you can point to a feed\nwith the `webFeed` property. This can be a simple URL, or an inline `DataFeed` object, with `encodingFormat` providing\nmedia type information, e.g. \“application/rss+xml\” or \“application/atom+xml\“.\n |
