Schema.org

Protocolo Semântico e de Dados

A shared vocabulary of types and properties for marking up structured data on web pages, maintained by a founding consortium of Google, Microsoft, Yahoo and Yandex under W3C Community Group process. Roughly 800 types and 1,500 properties cover creative works, events, organizations, people, places, products and actions. Schema.org markup is consumed by search engines and other aggregators to interpret page content, making it the most widely deployed structured-data vocabulary on the web by a very large margin. Included here as the incumbent general-purpose vocabulary that decentralized alternatives interoperate with or define themselves against.

Proprietário - Lista
  • World Wide Web Consortium
Origens Search engine structured data / SEO — created so that search engines could interpret page content consistently rather than each maintaining its own markup vocabulary; subsequently generalised to a broad web vocabulary used well beyond search
Banco de Dados N/A — a vocabulary, not a store; markup is embedded in web pages and consumed by crawlers
Linguagem de Consulta SPARQL where the vocabulary is used in RDF form; otherwise consumed by crawlers and parsers directly from page markup
Formatos de Dados JSON-LD (recommended by most consumers), RDFa, and Microdata. Vocabulary itself published as RDFS with regular versioned releases
Edição Colaborativa em Tempo Real N/A — vocabulary
Edição de Texto Rico N/A — vocabulary
Suporte Móvel N/A — vocabulary; markup is platform-independent
Suporte Web Yes — the web is its native and primary deployment surface
Aplicativos Nativos N/A — vocabulary
Termos Free — vocabulary terms under CC BY-SA 3.0; no fees or registration to use
Fundos Unknown — sponsor contributions are not itemised publicly
Baseado Em RDFS (vocabulary definition layer); JSON-LD, RDFa and Microdata (serialisations); W3C Community Group process
Compatibilidade com a Web Semântica Full RDF compliance — published as an RDFS vocabulary; JSON-LD and RDFa serialisations are RDF-native and SPARQL-queryable. Its type hierarchy is deliberately looser than a formal OWL ontology, favouring adoption over reasoning rigour
Maturidade / Padronização do Protocolo De facto standard — not a W3C Recommendation. Developed in a W3C Community Group with versioned releases and a public issue tracker; its authority comes from universal consumption by search engines rather than from formal standardisation
Tipo de Vocabulário / Ontologia General-purpose web vocabulary — approximately 800 types and 1,500 properties spanning CreativeWork, Event, Organization, Person, Place, Product, Action and their subtypes, plus hosted and external extensions (bib, auto, health-lifesci and others). Domain-agnostic by design
Padrão de Uso Embedded in web pages and reused by other vocabularies — the dominant pattern is inline markup consumed by search engines. Also widely reused as a base vocabulary by other specifications, including Murmurations (which uses Schema.org terms in its field library) and Blockchain Commons Gordian Envelope Known Values, both on this tab
