microdata-node
==============

[![Build Status](https://travis-ci.org/Janpot/microdata-node.svg)](https://travis-ci.org/Janpot/microdata-node)

Microdata parser. Aims to be compatible with http://www.w3.org/TR/microdata/#json and http://www.w3.org/TR/microdata-rdf/

Demo over at http://janpot.github.io/microdata-node.

## Example:

```js
var microdata = require('microdata-node');

var html =
  '<section itemscope itemtype="http://schema.org/Person"> ' +
  '  Hello, my name is ' +
  '  <span itemprop="name">John Doe</span>, ' +
  '  I am a ' +
  '  <span itemprop="jobTitle">graduate research assistant</span> ' +
  '  at the ' +
  '  <span itemprop="affiliation">University of Dreams</span>. ' +
  '  My friends call me ' +
  '  <span itemprop="additionalName">Johnny</span>. ' +
  '  You can visit my homepage at ' +
  '  <a href="http://www.JohnnyD.com" itemprop="url">www.JohnnyD.com</a>. ' +
  '  <section itemprop="address" itemscope itemtype="http://schema.org/PostalAddress">' +
  '    I live at ' +
  '    <span itemprop="streetAddress">1234 Peach Drive</span>,' +
  '    <span itemprop="addressLocality">Warner Robins</span>,' +
  '    <span itemprop="addressRegion">Georgia</span>.' +
  '  </section>' +
  '</section>';

var json = microdata.toJson(html, {
  base: 'http://www.example.com'
});
console.log(JSON.stringify(json, null, 2));
/*
{
  "items": [{
    "properties": {
      "address": [{
        "properties": {
          "addressRegion": [ "Georgia" ],
          "addressLocality": [ "Warner Robins" ],

      "name": [ "John Doe" ]
    },
    "type": [ "http://schema.org/Person" ]
  }]
}
*/

var jsonld = microdata.toJsonld(html, {
  base: 'http://www.example.com'
});
console.log(JSON.stringify(jsonld, null, 2));
/*

## API

microdata.toJson(html, [config])

parses the provided html to [microdata json](http://www.w3.org/TR/microdata/#json)

microdata.toJsonld(html, [config])

parses the provided html to [jsonld](http://json-ld.org/)

**options**

`config.base`: Base url to resolve url properties against.

`config.registry`: The [registry](http://www.w3.org/TR/microdata-rdf/#dfn-registry) associates a URI prefix with one or more key-value pairs denoting processor behavior.

`config.useRdfType`: (default `false`) If set to true, `rdf:type` predicates won't be converted to `@type` properties.

`config.strict`: (default `false`) Parse strictly according to spec. Does not try to be forgiving of malformed microdata.

`config.useNativeTypes`: (default `true`) Converts literals that are numbers or booleans to their corresponding JSOn type.
