No, but they are presented as a hash when calling `@host.facts`. I saw
it poking around with `foreman-rake console`:
irb(main):003:0> Host.first.facts.class
=> Hash

Can you share the facts hash that you have uploaded? If it had multiple
levels, they are stored as strings like you posted.
If you want to iterate through the actual FactValue object, it might
make it simple for you:
fact_values = FactValue.search_for("host = #{Host.first.fqdn}")
Or if you want to get ONLY the values with an actual value (so the ones
that are 'leaves' of the tree):
FactValue.search_for("host = #{Host.first.fqdn}").where.not(:value =>
nil)
