(I use URL instead of URI b/c I’ve yet to see the point of URN’s)

  1. No URL that ever returned 200 shall ever return a 404 for as long as the site exists.
  2. Any URL that returns a non-programmatic error shall provide a complete explanation (i.e. a 207 response) of what is necessary to receive a correct response.
  3. External URLs will always return a 200. Any external URL that fails to return 200 shall be replaced with an updated URL (in the case of 301) or another URL (i.e. google cache). If no meaningful URL can be constructed the maintainer must be notified upon discovery and for each load of a page with said URL.
