Mostly the same format, too. PG uses Dublin Core, with some additional
namespaces.

It's a big download, but look at the catalog in XML/RDF format
in the "offline catalogs" page of www.gutenberg.org

Also, you can find an RDF file in the generated files, with
just the metadata for that book. They're not as easy to find
at www.gutenberg.org, but they're part of the rsync-able contents
("mirroring how-to"). For example,

ftp://snowy.arsc.alaska.edu/mirrors/gutenberg/cache/generated/1661/ or
http://snowy.arsc.alaska.edu/mirrors/gutenberg/cache/generated/1661/

Specifically,
http://snowy.arsc.alaska.edu/mirrors/gutenberg/cache/generated/1661/pg1661.rdf
