I'm now close to a scruffy ad hoc solution for the integration of Open Graph data.
To finish the idea, I need access to the root HTML tag which Tiki emits for the pages it serves, in order to add the XML Namespace attributes for Open Graph (xmlns:og) and Facebook (xmlns:fb):
(html xmlns="http://www.w3.org/1999/xhtml" xmlns:og="http://ogp.me/ns#" xmlns:fb="https://www.facebook.com/2008/fbml")
(Edited to use braces instead of less-than/greater-than glyphs.)
Anyone knows which part (file, script) of Tiki emits this root HTML tag?
Thx & regards,
