Simplifies the construction of RDF strings (turtle, n-triples, SPARQL, etc.)

by taking care of correctly serializing values to their string representation

and automatically prefixing URIs.

## Usage

The heart of the library are [EcmaScript template string tag functions][template-literals].

All interpolated values are serialized according to the syntactic rules of the given RDF format.

Formats which support prefixes will automatically abbreviate the URIs and

return the prefix declarations according to the specific syntax.

### SPARQL

```js

import * as RDF from '@rdfjs/data-model' 

import { prefixes } from '@zazuko/rdf-vocabularies'

import namespace from '@rdfjs/namespace'

import { sparql } from '@zazuko/rdf-string'

const person = RDF.variable('person')

const PersonType = RDF.namedNode('http://example.com/Person')

const schema = namespace(prefixes.schema)

const name = "John"

const query = sparql`SELECT * WHERE {

  ${person} a ${PersonType} .

  ${person} ${schema.name} ${name} .

}`

query.toString()

```

The last line will return a complete query.

```sparql

PREFIX schema: 

SELECT * WHERE {

  ?person a  .

  ?person schema:name "John" .

}

```
