What is the difference between http-equiv="author" and name="author"?

Question

Hello I'm learning HTML5 and I'm wondering what is the difference between these two meta elements ?

<meta http-equiv="author" content="Jon Smith" />
<meta name="author" content="Jon Smith" />

Answer 1

The first is not valid, http-equiv is enumerated, i.e. it has a set of values that are valid for it and author is not one. (Its intended as a way to pass pragma data to the browser such as rendering instructions, not meta data like document properties.)

<meta name="author" content="Jon Smith" /> is valid.
