Oxigraph for JavaScript |
||||
======================= |
||||
|
||||
[![npm](https://img.shields.io/npm/v/oxigraph)](https://www.npmjs.com/package/oxigraph) |
||||
[![actions status](https://github.com/oxigraph/oxigraph/workflows/build/badge.svg)](https://github.com/oxigraph/oxigraph/actions) |
||||
[![Gitter](https://badges.gitter.im/oxigraph/community.svg)](https://gitter.im/oxigraph/community?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge) |
||||
|
||||
This package provides a JavaScript API on top of [Oxigraph](https://crates.io/crates/oxigraph), compiled with WebAssembly. |
||||
|
||||
Oxigraph is a graph database written in Rust implementing the [SPARQL](https://www.w3.org/TR/sparql11-overview/) standard. |
||||
|
||||
Oxigraph for JavaScript is a work in progress and currently offers a simple in-memory store with [SPARQL 1.1 Query](https://www.w3.org/TR/sparql11-query/) and [SPARQL 1.1 Update](https://www.w3.org/TR/sparql11-update/) capabilities. |
||||
|
||||
The store is also able to load RDF serialized in [Turtle](https://www.w3.org/TR/turtle/), [TriG](https://www.w3.org/TR/trig/), [N-Triples](https://www.w3.org/TR/n-triples/), [N-Quads](https://www.w3.org/TR/n-quads/) and [RDF/XML](https://www.w3.org/TR/rdf-syntax-grammar/). |
||||
|
||||
|
||||
It is distributed using a [a NPM package](https://www.npmjs.com/package/oxigraph) that should work with nodeJS 12+. |
||||
|
||||
```bash |
||||
npm install oxigraph |
||||
``` |
||||
|
||||
```js |
||||
const oxigraph = require('oxigraph'); |
||||
``` |
||||
|
||||
## Example |
||||
|
||||
Insert the triple `<http://example/> <http://schema.org/name> "example"` and log the name of `<http://example/>` in SPARQL: |
||||
```js |
||||
const { MemoryStore } = require('oxigraph'); |
||||
const store = new MemoryStore(); |
||||
const dataFactory = store.dataFactory; |
||||
const ex = dataFactory.namedNode("http://example/"); |
||||
const schemaName = dataFactory.namedNode("http://schema.org/name"); |
||||
store.add(dataFactory.triple(ex, schemaName, dataFactory.literal("example"))); |
||||
for (binding of store.query("SELECT ?name WHERE { <http://example/> <http://schema.org/name> ?name }")) { |
||||
console.log(binding.get("name").value); |
||||
} |
||||
``` |
||||
|
||||
## API |
||||
|
||||
Oxigraph currently provides a simple JS API. |
||||
It is centered around the `MemoryStore` class. |
||||
|
||||
The `NamedNode`, `BlankNode`, `Literal`, `DefaultGraph`, `Quad` and `DataFactory` types |
||||
are following the [RDF/JS datamodel specification](https://rdf.js.org/data-model-spec/). |
||||
|
||||
To import `MemoryStore` using Node: |
||||
```js |
||||
const { MemoryStore } = require('oxigraph'); |
||||
``` |
||||
|
||||
### `MemoryStore` |
||||
|
||||
#### `MemoryStore(optional sequence<Quad>? quads)` (constructor) |
||||
```js |
||||
const store = new MemoryStore(); |
||||
``` |
||||
|
||||
If provided, the `MemoryStore` will be initialized with a sequence of quads. |
||||
|
||||
#### `MemoryStore.dataFactory` |
||||
Returns a `DataFactory` following [RDF/JS datamodel specification](https://rdf.js.org/data-model-spec/). |
||||
|
||||
Example: |
||||
```js |
||||
const store = new MemoryStore(); |
||||
const ex = store.dataFactory.namedNode("http://example.com"); |
||||
const blank = store.dataFactory.blankNode(); |
||||
const foo = store.dataFactory.literal("foo"); |
||||
const quad = store.dataFactory.quad(blank, ex, foo); |
||||
``` |
||||
|
||||
#### `MemoryStore.prototype.add(Quad quad)` |
||||
Inserts a quad in the store. |
||||
|
||||
Example: |
||||
```js |
||||
store.add(quad); |
||||
``` |
||||
|
||||
#### `MemoryStore.prototype.delete(Quad quad)` |
||||
Removes a quad from the store. |
||||
|
||||
Example: |
||||
```js |
||||
store.delete(quad); |
||||
``` |
||||
|
||||
#### `MemoryStore.prototype.has(Quad quad)` |
||||
Returns a boolean stating if the store contains the quad. |
||||
|
||||
Example: |
||||
```js |
||||
store.has(quad); |
||||
``` |
||||
|
||||
#### `MemoryStore.prototype.match(optional Term? subject, optional Term? predicate, optional Term? object, optional Term? graph)` |
||||
Returns an array with all the quads matching a given quad pattern. |
||||
|
||||
Example to get all quads in the default graph with `ex` for subject: |
||||
```js |
||||
store.match(ex, null, null, store.dataFactory.defaultGraph()); |
||||
``` |
||||
|
||||
Example to get all quads: |
||||
```js |
||||
store.match(); |
||||
``` |
||||
|
||||
#### `MemoryStore.prototype.query(String query)` |
||||
Executes a [SPARQL 1.1 Query](https://www.w3.org/TR/sparql11-query/). |
||||
For `SELECT` queries the return type is an array of `Map` which keys are the bound variables and values are the values the result is bound to. |
||||
For `CONSTRUCT` and `ÐESCRIBE` queries the return type is an array of `Quad`. |
||||
For `ASK` queries the return type is a boolean. |
||||
|
||||
Example of SELECT query: |
||||
```js |
||||
for (binding of store.query("SELECT DISTINCT ?s WHERE { ?s ?p ?o }")) { |
||||
console.log(binding.get("s").value); |
||||
} |
||||
``` |
||||
|
||||
Example of CONSTRUCT query: |
||||
```js |
||||
const filteredStore = new MemoryStore(store.query("CONSTRUCT { <http:/example.com/> ?p ?o } WHERE { <http:/example.com/> ?p ?o }")); |
||||
``` |
||||
|
||||
Example of ASK query: |
||||
```js |
||||
if (store.query("ASK { ?s ?s ?s }")) { |
||||
console.log("there is a triple with same subject, predicate and object"); |
||||
} |
||||
``` |
||||
|
||||
#### `MemoryStore.prototype.update(String query)` |
||||
Executes a [SPARQL 1.1 Update](https://www.w3.org/TR/sparql11-update/). |
||||
The [`LOAD` operation](https://www.w3.org/TR/sparql11-update/#load) is not supported yet. |
||||
|
||||
Example of update: |
||||
```js |
||||
store.update("DELETE WHERE { <http://example.com/s> ?p ?o }") |
||||
``` |
||||
|
||||
### `MemoryStore.prototype.load(String data, String mimeType, NamedNode|String? baseIRI, NamedNode|BlankNode|DefaultGraph? toNamedGraph)` |
||||
|
||||
Loads serialized RDF triples or quad into the store. |
||||
The method arguments are: |
||||
1. `data`: the serialized RDF triples or quads. |
||||
2. `mimeType`: the MIME type of the serialization. See below for the supported mime types. |
||||
3. `baseIRI`: the base IRI to use to resolve the relative IRIs in the serialization. |
||||
4. `toNamedGraph`: for triple serialization formats, the name of the named graph the triple should be loaded to. |
||||
|
||||
The available formats are: |
||||
* [Turtle](https://www.w3.org/TR/turtle/): `text/turtle` |
||||
* [TriG](https://www.w3.org/TR/trig/): `application/trig` |
||||
* [N-Triples](https://www.w3.org/TR/n-triples/): `application/n-triples` |
||||
* [N-Quads](https://www.w3.org/TR/n-quads/): `application/n-quads` |
||||
* [RDF/XML](https://www.w3.org/TR/rdf-syntax-grammar/): `application/rdf+xml` |
||||
|
||||
Example of loading a Turtle file into the named graph `<http://example.com/graph>` with the base IRI `http://example.com`: |
||||
```js |
||||
store.load("<http://example.com> <http://example.com> <> .", "text/turtle", "http://example.com", store.dataFactory.namedNode("http://example.com/graph")); |
||||
``` |
||||
|
||||
|
||||
### `MemoryStore.prototype.dump(String mimeType, NamedNode|BlankNode|DefaultGraph? fromNamedGraph)` |
||||
|
||||
Returns serialized RDF triples or quad from the store. |
||||
The method arguments are: |
||||
1. `mimeType`: the MIME type of the serialization. See below for the supported mime types. |
||||
2. `fromNamedGraph`: for triple serialization formats, the name of the named graph the triple should be loaded from. |
||||
|
||||
The available formats are: |
||||
* [Turtle](https://www.w3.org/TR/turtle/): `text/turtle` |
||||
* [TriG](https://www.w3.org/TR/trig/): `application/trig` |
||||
* [N-Triples](https://www.w3.org/TR/n-triples/): `application/n-triples` |
||||
* [N-Quads](https://www.w3.org/TR/n-quads/): `application/n-quads` |
||||
* [RDF/XML](https://www.w3.org/TR/rdf-syntax-grammar/): `application/rdf+xml` |
||||
|
||||
Example of building a Turtle file from the named graph `<http://example.com/graph>`: |
||||
```js |
||||
store.dump("text/turtle", store.dataFactory.namedNode("http://example.com/graph")); |
||||
``` |
||||
|
||||
## How to contribute |
||||
|
||||
The Oxigraph bindings are written in Rust using [the Rust WASM toolkit](https://rustwasm.github.io/docs.html). |
||||
|
||||
The [The Rust Wasm Book](https://rustwasm.github.io/docs/book/) is a great tutorial to get started. |
||||
|
||||
To run the tests of the JS bindings written in JS run `npm test`. |
