URI/File scheme

Plan of action for updating the file: URI scheme:

Survey implementations of file: URIs:

What do they implement? How do they map file: URIs to various operating system special situations, including handling of character set transformations, inclusion of drive letters, remote mount directories, individual mount points, symbolic links or redirections?

What is useful common practice for getting interoperable results when creating file: URIs?

Based on this, update the Proposed Standard for file: URIs to be consistent with common current practice.
