Change metatag in Plone 5.0

Plone Support

I want to change the metatag in Plone 5.0:

Old:
<meta property="og:image" tal:attributes="content string:${context/absolute_url}/image"/>

New:
<meta property="og:image" tal:attributes="content string:${context/absolute_url}/@@images/image/preview"/>

In zope.interface.interface-plone.htmlhead.dublincore I can add the new tag, but the old one remains and is displayed under the new tag.

How can I overwrite the old tag so that only the new tag is displayed in the source code?

I have just realised that I had formatted the source text incorrectly in my first message. Now you can also see :slight_smile:

In the meantime I have realised that the tags are called in this file:
/portal_view_customizations/zope.interface.interface-plone.htmlhead.socialtags

Hier wird es so aufgerufen:

<span id="social-tags-body" style="display: none"
      itemscope itemtype="http://schema.org/WebPage">
  <span tal:repeat="tag view/body_tags"
        tal:attributes="itemprop tag/itemprop|nothing"
        tal:content="tag/content|nothing" />
</span>

Of course I can customise this file, leave it empty and create all meta tags again. But actually I would rather just change the necessary tags. Does anyone know how to do this?

The social tag viewlet use the "great" scale defintion to deliver the images, use this scale?

That looks good, but how can I customise the social.py?
