nmspc v0.3.0

Namespace

A collection of RDF namespaces as javascript classes.

Usage

Install with npm install nmspc. Each namespace has a base URI and a prefix label for the sake of writing prefixed names (see the Turtle spec IRIs and the Wikipedia article on compact URIs). Other properties return the full URI of each resource defined in the namespace.

import * as NS from 'nmspc';

console.log("DC:", NS.DC.baseURI, NS.DC.creator);
// outputs: DC: http://purl.org/dc/terms/ http://purl.org/dc/terms/creator
console.log("RDF:", NS.RDF.baseURI, NS.RDF.Alt);
// outputs: RDF: http://www.w3.org/1999/02/22-rdf-syntax-ns# http://www.w3.org/1999/02/22-rdf-syntax-ns#Alt

Note

There is a generator written in typescript in the project. To generate namespace classes:

• Clone this project git clone git@github.com:matthieubosquet/namespace.git
• Install dev dependencies running npm install
• Edit src/generator/runner.ts adding in your own ontology as NodeJS Readable stream
• Run npm run build-namespace to generate a namespace class corresponding to your ontology

The prefixes used/recognised/required by the generator are:

• vann:preferredNamespacePrefix for the prefixLabel property
• vann:preferredNamespaceUri for the baseUri property
• rdfs:isDefinedBy for every name defined in the namespace
• dc:issued for the version property

See the matthieubosquet/ontologies repository for example ontologies serialised as turtle and described using those aforementioned prefixes and OWL 2 annotation properties where possible.
