Do you think these are in public domain?

Like feeds here:

http://www.federalreserve.gov/feeds/

or in general, the feeds listed here:

http://www.usa.gov/Topics/Reference_Shelf/Libraries/RSS_Library.shtml

So they can be published on a website publishing Adsense, which means it's commercial?

Almost everything put out by the government is in public domain. The exception is when the government is publishing information they have licensed from a private individual or business, in which case the government has the permission to publish it, but you do not.

If there is no copyright statement on government data, it is usually public domain.
