This is an area where URI resolution works differently to file path resolution (on some systems), so it's not just an academic point. If you don't include the trailing "/" on a directory used as a base URI, then the final directory segment gets dropped when performing URI resolution. Developers working in this space will know this anyway, but I think it's important. Also, "file:///home/user" and "file:///home/user/" are different URIs per RFC3986. It's usially a good idea to avoid gratuitous URI aliasing, which suggests it would be good practice to always include the trailing "/". #g --
