Might be used as a hint as to which tld index a site should included, especially for non-U.S.-English language sites. (And just good form to include it anyway.)
<meta name="revisit-after" content="1 days">
You can't tell spiders when to come back. You can however, tell them when not to come back. This is like saying don't come any more frequently then once a day (fortunately for most people who use it without knowing what it is, the majority of spiders ignore it.

In a validated site this will be stated in the doc-type.
<meta name="rating" content="Safe For Kids">
This is for parent control although the rating "Safe For Kids" does not exist. You may use however "general," "mature," "restricted" and "14 years.". I believe SE's assume your content as "general" even if you don't specify, so for most people it is not necessary (could be wrong on that last statement)
<meta name="distribution" content="GLOBAL">
This is mainly for intra net admistrators who set pages for local or internal use. But for 99% of us this has no use. The content for this tag can be "global," "local" or "iu" (internal Use)

That's a common misunderstanding - I used to think so too. But the "EN" we see in the doctype is just the language that the DTD itself is written in, not the language of the document's content.
