Fast, simple & flexible API for the Schema.org Vocabulary (and vocabulary extensions!) for Node and Browsers

⌘ Empowers the semantic web: Schema.org has become the standard vocabulary for the semantic web. This Schema.org Adapter gives developers a clear API to access the schema.org vocabulary in a simple way.
★ Clear data model: The data model of the rdf-based, machine-readable version of Schema.org is slightly adapted (see documentation for details) to create the clear and pragmatic data model of this Schema.org Adapter.
↹ Supports external vocabularies: The Schema.org Adapter is lightweight because it does NOT include the vocabulary data, instead it allows the user to input his needed local/remote vocabularies (JSON-LD or URL to JSON-LD). This gives the user the possibility to specify the version/part of Schema.org he/she needs, and also to use external vocabularies.
♻ Built-in reasoning: The API of Schema.org Adapter offers functions and parameters to enable built-in reasoning on the used vocabulary-terms (e.g. resolution of properties, sub-classes, ranges, etc.)
Api documentation generated by JSDoc hosted at GitHub.
Use of filters
It is possible to filter the results of some functions by passing a filter object - The filter options can be:
- "isSuperseded": boolean (e.g.
false-> only vocabulary elements that are not superseded will be returned)
- "termType": string/Array (e.g.
['Property', 'Class']-> only vocabulary elements that are properties or classes will be returned)
- "fromVocabulary": string/Array (e.g.
['http://schema.org/']-> only vocabulary elements that come from a specific vocabulary will be returned (this may be interesting if you use additional external vocabularies))
