@rdfjs/namespace
Named Node builder.
Usage
The package exports a factory to create builders for Named Nodes.
The baseIRI
given to the factory will be used together with the parameter given to the builder to create Named Nodes.
Factory
The factory must be called with the baseIRI
as a string:
const builder = namespace('http://example.org/base-iri#')
An optional factory can be defined:
const builder = namespace('http://example.org/base-iri#', { factory: customFactory })
By default @rdfjs/data-model
is used.
Builder
The builder can be called in three different ways:
- function call: (
builder('property')
) - tagged template string: (
builder`property`
) - property: (
builder.property
)
Calling the builder using the propery requires Proxy support. At the moment IE11 is the only major platform which doesn't support Proxy.
Example
This example shows how to create a builder and create Named Nodes using the three different ways. The properties of the Named Nodes are written to the console.
import namespace from '@rdfjs/namespace'
const schema = namespace('http://schema.org/')
const hasPart = schema('hasPart')
console.log(hasPart.termType) // NamedNode
console.log(hasPart.value) // http://schema.org/hasPart
const person = schema`Person`
console.log(person.termType) // NamedNode
console.log(person.value) // http://schema.org/Person
const comment = schema.Comment
console.log(comment.termType) // NamedNode
console.log(comment.value) // http://schema.org/Comment
