Clarification needed[edit]

I see this template added to images that do not specify the author or the date of death of the author. I feel more guidance is needed in the template text, or a link to guidance should be added. For example, is evidence of a search for the author needed if the author is unknown? What about images that have descriptions that only state painted in the 18th Century? 19th century? I have posted a note to here from Commons talk:Licensing#PD-old-100 clarification needed -84user (talk) 18:09, 7 January 2011 (UTC)

Some examples with no author given: File:Klosowski.jpg (no author); File:AntoineClaudet.png (assumes without evidence that author died before 1910, or some other unstated assumption). Examples of correct template placing in my opinion: File:AsmusCarstens.png (painter died in 1798); File:Balaklava-camp.png (photographers died in 1888 and 1907). -84user (talk) 18:18, 7 January 2011 (UTC)

Such images should probably be nominated for deletion. I'm also concerned about US law regarding unpublished images whose author has been dead for over 100 years, can anyone clarify this? Dcoetzee (talk) 06:12, 8 January 2011 (UTC)
There's no set rule of thumb, but I get the impression--and this just might be my own echo chamber here--that 100-110 year lifespan is a safe outer bound, and we should generally assume an artist was 20 unless we have reason to assume otherwise. Thus Antoine Claudet would safely be PD-old-70 but not PD-old-100.--Prosfilaes (talk) 07:57, 8 January 2011 (UTC)
In the U.S., still-unpublished works (or ones published since 2003) where the author has been dead for over 70 years are now public domain. If the author is not known, 120 years from creation. In most cases, the tag should be changed to a separate PD-old variant with a lower number. The only country I am aware of with 100 pma terms is Mexico, and they just increased from 75 pma to 100 pma in 2003, and I don't think it was retroctive -- so works by authors who died in 1927 or before are still OK there, I believe. So, I don't think this tag represents any actual legal line anywhere, other than being a tag which is the outermost possible extent of known theoretical protections.

Côte d'Ivoire has a life+99 duration (or 99 years from publication for posthumous works), but the rule of the shorter term, according to List of countries' copyright length. Columbia is life+80, and there were a couple life+75 in the list.
Indeed, I forgot about the Ivory Coast. They apparently went to 99 years pma in a late 1996 law, but I can't tell if it was retroactive or not, nor can I find what their previous terms were. There are other {{PD-old-80}} etc. templates for some of those other terms you mention, yes. Carl Lindberg (talk) 16:33, 11 January 2011 (UTC)
