but where, during that term, the author's identity becomes commonly known, the term provided in section 6 applies.
That's what I see as a potential challenge for PG Canada. If we do clear anything under a rule based on this provision, how do we prepare for the small chance of someone coming forward with an author's name for a previously considered anonnymous work?
"A previously considered anonnymous work" can only become something other than "anonymous" during that fifty year post-publication term. ("during that term..." Since a PG Canada can't assume public domain status until publication+50 has run out, and the owner of copyright can only claim the life+ term before publication+50 runs out, a PG Canada doesn't have to worry one little bit. If the author's identity becomes known on New Year's Eve, then the work just continues under copyright and we wouldn't have been able to use it before then anyway. If the author's identity becomes known of New Year's Day, then it doesn't change the fact that copyright has expired.
