Should og:image and og:url put in <meta> or <link>?

Question

For og:image and og:url, since they have URL, can I place them in a link tag instead of a meta tag, and is it preferable?

I don't know about other major consumers of the OGP so this might not be a problem for your case, but if you plan to implement it for Facebook,

stick to meta tags.

Doing a quick live test with the open graph debugger and fiddling with the og: tags, it appears that facebook only recognizes them if they are placed in s.

If you create an empty HTML file with a single og:url tag in its section, upload it to any URL and run it through the debugger above, both

and

edit or, as suggested in the comments

will fail to parse and return the original URL, while

parses correctly and returns the contents of The Rock on IMDb instead. At the end of the day semantics are nice, but working code is even better.
