Can you explain structured data errors in webmaster tools?
When I look at Google Webmaster Tools, I am finding multiple structured data errors on almost every page of my site. They appear to be related to each and every comment made on the page or post.
One set of errors says, "Missing: updated" and the other "Missing: Author." Both end up pointing, as I mentioned, at the comments. The specific text of the "Missing: updated" message is "Error:If this markup is about a person, at least 2 of the following fields are needed: organization, location, or role. See the people help page for more information." The "people help page" isn't help to me at all.
Can someone tell me what needs to be done to resolve these errors?
