  3 | Open Graph, Twitter Card, and oEmbed Metadata Collector
  4 | 
  5 | [![Build Status](https://secure.travis-ci.org/hueniverse/metaphor.svg)](http://travis-ci.org/hueniverse/metaphor)
  6 | 
  7 | **metaphor** uses three web protocols to obtain information about web resources for the purpose of embedding smaller
  8 | versions of those resources in other web resources or applications. It is very common for applications to expand
  9 | links into a formatted preview of the link destination. However, obtaining this information requires using multiple
 10 | protocols to ensure maximum coverage.
 11 | 
 12 | This module uses the [Open Graph protocol](http://ogp.me/), [Twitter Cards](https://dev.twitter.com/cards/overview),
 13 | the [oEmbed protocol](http://oembed.com/), and information gathered from the resource HTML markup and HTTP headers.
 14 | It takes an optimistic approach, trying to gather information from as many sources as possible.
 15 | 
 16 | ## Usage

 97 | ### `new Metaphor.Engine([options])`
 98 | 
 99 | A reusable engine used to set global processing settings for each description where:
100 | - `options` - optional settings where:
101 |     - `providers` - if `true`, the [oEmbed](http://oembed.com/) providers list file is used to look up
102 |       resources when oEmbed [discovery](http://oembed.com/#section4) doesn't work. The module ships with
103 |       a copy of the providers.json file. To use a different provider list, pass an array compatible with
104 |       the providers.json format. If `false`, oEmbed usage will be limited to discovery only. Defaults to
105 |       `true`.
106 |     - `whitelist` - an optional array of HTTP or HTTPS URLs allowed to be described. The URLs use the
107 |       format `{scheme}://{domain}/{path}` where:
108 |         - `scheme` - must be `'http'` or `'https'`. The module will ignore which protocol is specified
109 |           and will describe both schemes.
110 |         - `domain` - the domain name with an optional `*.` prefix. The `'www.'` prefix is automatically
111 |           removed and ignored.
112 |         - `path` - if specified, but be `'*'` or a path where at least one segment is `'*'`.
113 |     - `maxWidth` - an optional integer passed to the oEmbed endpoint to limit the maximum width of elements
114 |       in the description. While the protocol requires providers to comply, many do not so this is at best
115 |       a recommendation.
116 |     - `maxHeight` - an optional integer passed to the oEmbed endpoint to limit the maximum height of elements
117 |       in the description. While the protocol requires providers to comply, many do not so this is at best
118 |       a recommendation.
119 |     - `preview` - can be set to:
120 |         - `true` - a HTML preview is generated and returned in `description.preview`. This is the default.
121 |         - `false` - no HTML preview is generated.
122 |         - a function with the signature `function(description, options, callback)` where:
123 |             - `description` - the resource description document.
124 |             - `options` - the engine settings.
125 |             - `callback` - the callback method using the signature `function(preview)` where:
126 |                 - `preview` - the HTML preview string or `null` to skip setting a preview.
127 | 	- `summary` - if `true`, a `summary` object is include with the description which contains the same
128 | 	  data provided by the `preview`. Defaults to `false`.
129 | 	- `tweet` - if `true`, tweets are parsed to include specific information required to show a proper
130 | 	  embeded tweet without the use of the Twitter scripts. Defaults to `false`.
131 |     - `maxSize` - the maximum image size in bytes allowed to be included in an image preview. The limit
132 |       is only enforced when creating a `preview` (ignored when `preview` is disabled). When set, an HTTP
133 |       HEAD request is made to each image URL to obtain its size. Defaults to `false`.
134 |     - `css` - if set to a URL, it is used as a style sheet link in the `preview`. Defaults to `false` (no link).
135 |     - `script` - if set to a URL, it is used as a script link in the `preview`. Defaults to `false` (no link).
136 | 
137 | ### `engine.describe(url, callback)`
138 | 
139 | Described a web resource where:
140 | - `url` - the resource HTTP or HTTPS URL.
141 | - `callback` - the callback function using the signature `function(description)` where:
142 |     - `description` - the **metaphor** description object.
143 | 
144 | Note that the `describe()` method does not return errors. Errors are optimistically ignored and best effort
145 | is made to use as many sources for describing the `url`. The `description` always includes the following
146 | two properties:
147 | - `type` - set to `'website'` when the type is unknown.
148 | - `url` - the resource canonical URL, set to the requested `url` when no source can be utilized.
149 | 
150 | When resources are successfully used, the `description` includes the `sources` property set to an array
151 | of one or more of:
152 | - `'resource'` - information was gathered from the resource HTML page.
153 | - `'ogp'` - Open Graph protocol tags (`og:`) used.
154 | - `'twitter'` - Twitter Card tags (`twitter:`) used.
155 | - `'oembed'` - oEmbed service used.
