## Summary
"Died more than 100 years ago" is a heuristic method used to determine the copyright status of a creator, specifically whether their works are in the public domain due to the expiration of copyright protections. This applies to countries with a post-mortem auctoris (PMA) term of 100 years or less, meaning the creator's death occurred at least 100 years prior.

## Key Facts
- A heuristic for determining copyright status of a creator.
- Used in jurisdictions where the post-mortem auctoris term is 100 years or shorter.
- Indicates that copyrights on works have expired if the author died 100 years or more ago.
- Part of a broader classification of methods for assessing copyright status.
- Distinct from other similar heuristics like "died more than 50, 70, or 80 years ago."
- Applies to countries with a 100-year PMA or shorter duration.
- Facet of post-mortem auctoris (PMA) copyright law.

## FAQs
### Q: What does "died more than 100 years ago" mean in copyright law?
A: It means that the creator's death occurred at least 100 years prior, which triggers the expiration of copyright protections in jurisdictions with a 100-year post-mortem auctoris term.

### Q: Which countries use this heuristic?
A: Countries where the post-mortem auctoris term is 100 years or shorter, such as those with a 100-year PMA or shorter duration.

### Q: How does this differ from other similar heuristics?
A: Unlike "died more than 50, 70, or 80 years ago," this heuristic specifically applies to a 100-year threshold, distinguishing it from shorter-term copyright expiration rules.

### Q: What happens to a creator's works if they died more than 100 years ago?
A: Their works enter the public domain, meaning no copyright restrictions apply, provided the jurisdiction follows a 100-year PMA or shorter term.

### Q: Is this the only method for determining copyright status?
A: No, it is one of several heuristics used, depending on the jurisdiction's copyright laws and the specific duration of the post-mortem auctoris term.

## Why It Matters
The heuristic "died more than 100 years ago" is significant in copyright law as it provides a clear, measurable threshold for determining public domain status. It ensures that works by creators who died over a century ago are freely accessible, promoting cultural heritage and educational use. This method is particularly relevant in countries where the post-mortem auctoris term is 100 years or shorter, standardizing the process for identifying public domain works. By establishing a consistent 100-year benchmark, it simplifies legal assessments and encourages the preservation and dissemination of historical works.

## Notable For
- Serves as a specific threshold for copyright expiration in certain jurisdictions.
- Distinguishes itself from other similar heuristics with a 100-year cutoff.
- Facilitates the identification of public domain works in countries with a 100-year PMA or shorter term.
- Provides a clear, actionable criterion for determining copyright status.
- Aligns with broader post-mortem auctoris principles in copyright law.

## Body
### Definition and Scope
"Died more than 100 years ago" is a heuristic used to assess copyright status, particularly in jurisdictions where the post-mortem auctoris term is 100 years or shorter. It indicates that the creator's death occurred at least 100 years prior, leading to the expiration of copyright protections.

### Legal Application
This heuristic applies to countries with a 100-year PMA or shorter duration, ensuring that works by creators who died over a century ago are in the public domain. It is distinct from other similar heuristics, such as "died more than 50, 70, or 80 years ago," which apply to different PMA terms.

### Impact on Works
Works by creators who died more than 100 years ago are considered public domain, meaning they can be freely used, copied, and distributed without copyright restrictions. This promotes cultural heritage and educational access to historical works.

### Comparison to Other Heuristics
Unlike other similar heuristics, "died more than 100 years ago" specifically targets a 100-year threshold, providing a clear and consistent standard for determining public domain status in applicable jurisdictions.

### Role in Copyright Law
This heuristic is part of a broader framework for assessing copyright status, particularly in post-mortem auctoris systems. It ensures that works by deceased creators are properly identified and managed in the public domain.
