Can I suggest a section of a site only?

I work for a government department in Australia. Our remit is quite varied: we deal with environmental issues, recreational parks, museums and public safety. Our site is structured in several groups: the main departmental topics are located under "example.gov", with other sections of the site (eg dedicated to a specific park or museum) located in subfolders - eg "example.gov/museumname".

Is it OK to submit "example.gov" in one category (e.g. Government) and "example.gov/museumname" in another (e.g. Society and Culture : History)? I'm aware that this would be "overlapping content" (as the main government listing includes everything), but would appear to be a more accurate representation of the content.

Thanks!

For large non-commercial websites with a wide scope, it's OK to list individual sections - provided that they have useful, significant and unique content.

Getting down to examples, if you have several museums in the same city, we might prefer to list a museums index page rather than each one individually. Similarly for parks and public safety. OTOH, if they are in different cities, we'd probably list each one within the appropriate city category.
