According to the OGP documentation it is allowed to have multiple entries of the same tag with different values. In this case, tag properties are read in the order they appear. In the following snippet image, rock1 has a width and height of 300, rock2 has no properties, and rock3 has a height of 1000.

<meta property="og:image" content="https://example.com/rock1.jpg" />
<meta property="og:image:width" content="300" />
<meta property="og:image:height" content="300" />
<meta property="og:image" content="https://example.com/rock2.jpg" />
<meta property="og:image" content="https://example.com/rock3.jpg" />
<meta property="og:image:height" content="1000" />

Q: Is it possible to have multiple types?

Is it possible to have a construction like this:

<meta property="og:type" content="article" />
<meta property="og:locale" content="de" />
<meta property="og:url" content="https://example.com/article-1.html" />
...
<meta property="og:article:author" content="https://www.example.com/autors/john-doe" /> 

<meta property="og:type" content="profile" />
<meta property="og:profile:first_name" content="John" /> 
<meta property="og:profile:last_name" content="Doe" /> 
<meta property="og:profile:username" content="johndoe123" /> 
<meta property="og:profile:gender" content="male" /> 

Such constructions, in general type arrays, are possible while using structured data of Schema.org - but I can't find anything about this for Open Graph.

I've tried to test such (more completed) code with some debugging tools - this didn't bring me closer to an answer:

• The FB debugger recognizes only the first type,
• This one recognizes only last type
