collective.opengraph 1.0

Plone opengraph

collective.opengraph

This package is a part of the Plone’s collective.fg bundle. It adds the opengraph metadata to your HTML head section.

Supported metadata:

• og:site_name name of the site

• og:url url of the webpage

• og:title title of the webpage

• og:description description of the webpage

• og:image your webpage image (either ‘image’ field of your context or collective.contentleadimage one)

from the control panel you can manage following settings: - the default og:type - which content types should be opengraph metadata aware

Customization

One of the goals of this package is to allow developers extend the default metadata definition. It’s availabe threw IOpengrapMetatags adapter:

from collective.opengraph.interfaces IOpengraphMetatags
from collective.opengraph.viewlets import ATMetatags

class MyATMetatags(ATMetatags):

    implements(IOpengrapMetatags)

    @property
    def metatags(self):
        tags = super(MyATMetatags, self).metatags
        tags.update({'og:newtype': 'custom value'})
        return tags

You can also customize existing og values:

from collective.opengraph.interfaces IOpengraphMetatags
from collective.opengraph.viewlets import ATMetatags

class AnotherMetatags(ATMetatags):

    implements(IOpengrapMetatags)

    @property
    def title(self):
        return '%s - Lorem ipsum' % self.context.Title()
