Look at all these meta tags

I didn't know about half of these...

Found this on IBM's source. I have never heard of half of these meta tags. Are all of these actually used?

Perhaps it's something to do with xml???

It looks like IBM has an internal tool that uses the meta elements for some special purpose.

Here [vancouver-webpages.com] is a "Dictionary of meta tags". It includes a link to the infamous Dublin Core [purl.org] metadata element set.

I sometimes wish I didn't even know about these things. I certainly don't use or plan to use any of it.
