Is there a standard site structure format? The use of this would be for export and import into a CMS or framework to define the urls, content, metadata for a website. Something tool agnostic would be the goal.

JSON, YAML, XML, whatever. Maybe something like:

{
  'baseurl': 'http://example.com',
  'site': [
    {'slug': '/', 'title': 'ExampleCo. Inc.'},
    {'slug': '/about', 'title': 'About Our Company'},
    {'slug': '/services', 'title': 'Our Services'},
    {'slug': '/products', 'title': 'Products'},
    {'slug': '/products/purchase', 'title': 'Purchase Products Now'},
    {'slug': '/products/downloads', 'title': 'Downloads'},
    {'slug': '/contact', 'title': 'Contact Us'}
   ]
}

My thinking is that it would allow you to quickly populate a content management system or framework with a generic site navigational structure.

Does something like this exist?
