Schema.org for Developers
This is a placeholder page for developer-oriented information about schema.org. In particular it gives access to machine-readable representations of our schemas.
Machine Readable Term Definitions
Machine-readable definitions of individual terms are available as RDFa, embedded into the term page html.
Vocabulary Definition Files
To assist developers, files containing the definition of the current version of the Schema.org vocabulary is available for download in common RDF formats.
Older release versions can be found (under
data/releases/) in GitHub.
Select the file and format required and click Download. The CSV format downloads are split across two files: Types includes definitions of Types and Enumeration Values, including lists of associated properties; Properties contains property definitions.
File schemaorg-current-http contains the definition of all terms in, all sections of, the vocabulary. The file schemaorg-all-http contains the definition of all terms in, all sections of, the vocabulary, plus terms retired from the vocabulary (See the attic section for details).
For those preferring to use https based definitions of Schema.org terms, these equivalent definitions are available in the schemaorg-current-https and schemaorg-all-https files. For more information on using http or https based terms see the FAQ for details.
The following representations are experimental and may change or be removed in future releases.
D3 RDFS in JSON-LD
The structure of the file differs from the above vocabulary definition files, in that
values are converted into
rdfs:range values using
owl:unionOf to capture the multiplicity of values.
Included in the range values are the, implicit within the vocabulary, default values of Text, URL,
This file has been made available to enable the representation of the vocabulary in some OWL-based modeling tools. The mapping into OWL is an approximation, and should not be considered an authoritative definition for Schema.org's terms; see datamodel page for details. As an experimental feature, there are no expectations as to its interpretation by any third party tools.
