prefix-ns

This npm module gives easy access to the prefixes and namespaces of prefix.cc. Upon installation of this module the latest dump is downloaded from prefix.cc and stored locally. The dump is only updated when the module is re-installed. A default dump (data.json) is available if the download of the dump fails.

Usage

let prefixns = require('prefix-ns');

//The following method returns an array of all prefixes.
let allPrefixes = prefixns.getPrefixes();
console.log(allPrefixes);

// --> ['rdf', 'foaf', ...]

//The following method returns the namespace of a given prefix.
//null is returned when the prefix is not found.
let namespace = prefixns.getNamespaceViaPrefix('foaf');
console.log(namespace);

// --> http://xmlns.com/foaf/0.1/

//The following method returns the prefix of a given namespace.
//null is returned when the namespace is not found.
let prefix = prefixns.getPrefixViaNamespace('http://xmlns.com/foaf/0.1/');

//The following method returns a map where the prefixes are the keys and the namesapces are the values.
