OpenGraph for plone4
This packages provides Open Graph tags similar to those built in in plone 5. Basically this is an attempt to backport the social media viewlet of plone.app.layout in plone 5 to plone 4.
What is Open Graph
Open Graph is a specification developed by Facebook to provide information about a webpage. This information is used by social media sites to get title, author, description, url, images and more in order to create a marked up link.
- add collective.ogtags to your eggs and run buildout
- go to the add-ons page in the plone control panel and install collective.ogtags
- If you use custom image fields write an adapter for collective.ogtags.interfaces.IOGTagsImageProvider and your content-type to get this image (optional because collective.ogtags already registers the adapters for generic dexterity and archetype CT searching for “image” and “leadImage” fields)
Go to the ogtags settings in the plone control panel. Provide as much of the following settings as possible:
- Site name:
- Provide the name of your site here.
- Facebook username:
- Provide your facebook username. You can find this by going to your facebook page. The format is: https://www.facebook.com/<facebook_username>
- Facebook app id:
- Provide your facebook app id. Go to https://developers.facebook.com/apps, choose your app and look for your app id in the description.
- Twitter username:
- Provide your twitter name. The @-sign included, for example: @zestsoftware
- Default image:
- Provide the URL to an image to be used in case no other image can be found. By default this will be /logo.png.
