Open Graph Protocol Tools
Open Graph protocol enhances information associated with a webpage through key-value pairs included as <meta>
elements in your HTML. This additional data is consumed by social sharing sites, populating a story preview for shared links and referenced objects in the social graph.
This project includes tools to validate and sanitize inputs before generating Open Graph protocol markup on your webpages. This project standardizes outputs for easy indexing by consuming agents. We also let you consume remote pages and attempt to parse the Open Graph tags there of.
Consuming agents
Facebook indexes Open Graph protocol markup found on pages shared in a member's social news feed. This markup also enhances social news feed stories generated by the Like button social plugin and Facebook Share.
Open Graph protocol markup turns webpages into objects within the Facebook social graph, increasing search exposure and uniquely classifying your site and story type within the social news feed.
The Facebook Object Debugger displays a Facebook interpretation of your site's Open Graph protocol content.
mixi Check
Mixi indexes Open Graph protocol markup in its mixi Check social sharing service.
Google+ Snippet
Google indexes Open Graph protocol markup to populate a Google+ activity post.
Structure
The Application includes a number of core objects in the Open Graph protocol. They are all located under the OpenGraph
namespace.
Objects:
OpenGraph\Objects\Article
OpenGraph\Objects\Book
OpenGraph\Objects\Profile
OpenGraph\Objects\Video
Media:
OpenGraph\Media\Audio
OpenGraph\Media\Image
OpenGraph\Media\Video
Core Open Graph protocol
Support for structured properties for image, video, and audio objects.
Declare a new OpenGraphProtocol
object and set some properties. Add structured media objects.
Output your OpenGraphProtocol object as HTML <meta>
elements. Default configuration uses the property
attribute from RDFa. Change to name
if you prefer HTML specification compliance and consuming agents support the name
attribute as a property
fallback.
Global objects
Build global objects and attributes. Set time values using either an ISO 8601 formatted string or a DateTime object. DateTimes will be converted to the UTC timezone before output for consistency.
Convert a global object to <meta>
elements just as you would with OpenGraphProtocol.
Combined
A common use case might be storing Open Graph protocol objects in a Controller for use by your web application. You can add each object to an array and later iterate through the array for <head prefix="">
and <meta>
outputs.
Fetching
Commonly used in applications, fetching the contents of a remote page to get the Open Graph information can be a tedious task. Often time, you will have to get a webpage, write some regex to get the IMGs from it and MAYBE it'll work. Let us fix that.
That'll give you something that looks like this:
array (size=6) 'description' => string 'Ayman al-Zawahiri, who has warned against Islamist parties taking part in elections, is emerging as a stronger leader than predicted' (length=132) 'title' => string 'Al Qaeda leader's 'I told you so' on Egypt' (length=42) 'type' => string 'article' (length=7) 'url' => string 'http://www.cnn.com/2013/08/15/opinion/bergen-zawahiri-egypt/index.html' (length=70) 'site_name' => string 'CNN' (length=3) 'image' => string 'http://i2.cdn.turner.com/cnn/dam/assets/130815122452-08-egypt-0815-story-top.jpg' (length=80)
We're looking for ways to improve it still (find an image in the page's contents if og:image
isn't specified). Stay tuned.
