Add more metadata to data dump

Question

I think that there should be more metadata in data dump. There are currently 4 sites in the dump, and more will come (SE 2.0 sites, stackapps.com).

I am proposing that a new file is added to data dump for each site. This would help to create tools that access several data dumps.

I am thinking this kind of data:

metadata.xml:

<metadata>
  <dataDumpVersion>1.0</dataDumpVersion>
  <name>Stack Overflow</name>
  <url>http://stackoverflow.com/</url>
  <description>Stack Overflow is a programming Q & A site that's free. Stack Overflow is for professional and enthusiast programmers, people who write code because they love it.</description>
