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 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 Several kinds of information can be provided: We encourage the provision of “name”, “text”, “datePosted”, “expires” (if appropriate), “category” and 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 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 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 | CreativeWork | about, abstract, accessMode, accessModeSufficient, accessibilityAPI, accessibilityControl, accessibilityFeature, accessibilityHazard, accessibilitySummary, accountablePerson, acquireLicensePage, additionalType, aggregateRating, alternateName, alternativeHeadline, announcementLocation, assesses, associatedMedia, audience, audio, author, award, awards, category, character, citation, comment, commentCount, conditionsOfAccess, contentLocation, contentRating, contentReferenceTime, contributor, copyrightHolder, copyrightNotice, copyrightYear, correction, creativeWorkStatus, creator, creditText, dateCreated, dateModified, datePosted, datePublished, description, disambiguatingDescription, discussionUrl, diseasePreventionInfo, diseaseSpreadStatistics, editEIDR, editor, educationalAlignment, educationalLevel, educationalUse, encoding, encodingFormat, encodings, exampleOfWork, expires, fileFormat, funder, genre, gettingTestedInfo, governmentBenefitsInfo, hasPart, headline, identifier, image, inLanguage, interactionStatistic, interactivityType, isAccessibleForFree, isBasedOn, isBasedOnUrl, isFamilyFriendly, isPartOf, keywords, learningResourceType, license, locationCreated, mainEntity, mainEntityOfPage, maintainer, material, materialExtent, mentions, name, newsUpdatesAndGuidelines, offers, pattern, position, potentialAction, producer, provider, publicTransportClosuresInfo, publication, publisher, publisherImprint, publishingPrinciples, quarantineGuidelines, recordedAt, releasedEvent, review, reviews, sameAs, schemaVersion, schoolClosuresInfo, sdDatePublished, sdLicense, sdPublisher, size, sourceOrganization, spatial, spatialCoverage, sponsor, subjectOf, teaches, temporal, temporalCoverage, text, thumbnailUrl, timeRequired, translationOfWork, translator, travelBans, typicalAgeRange, url, usageInfo, version, video, webFeed, workExample, workTranslation |
