That is not very surprising, since meta tags are yet to be implemented.
Not only are they "not yet" implemented in MediaWiki, but they are not implemented in any wiki software anywhere, as far as I know. And this is not because the problem hasn't been considered, but because those who have considered the problem have chosen to leave out this feature.
Many articles contain complicated and advanced usages of HTML, and that seem to work out fine.
I don't think anybody is happy with the need for HTML markup in wiki pages.
It also doesn't have the possibilites of metadata.
You can of course implement this in the wiki parser and store the harvested metadata in a database table. But how will that database table be used? Will it be useful enough to motivate users to input the necessary metadata in Wikipedia pages? Go ahead and show me. I'll believe it when I see it. The measure of your success is the number of Wikipedia pages that contain such metadata. Today it is zero.
