Yoast platinum, news plug-in & meta properties

[jgodwin]

I have followed some of the discussions about Yoast and the news plug-in, but have not found specific information about the use of meta properties. One of our competitors is successfully using about 15 meta properties to gain news ranking. They list the publisher as Facebook. Is this coding part of the Yoast package or hard coding? As an example:

That part is probably configured by the Yoast plugin as it looks pretty much the same as the set-up that we have.
