# died less than 70 years ago > heuristic for determination of "copyright status as a creator" (P7763) for authors **Wikidata**: [Q96095416](https://www.wikidata.org/wiki/Q96095416) **Source**: https://4ort.xyz/entity/died-less-than-70-years-ago ## Summary "Died less than 70 years ago" is a heuristic used to determine the copyright status of a creator (property ) by checking whether the author’s date of death falls within the last 70 years. It is the opposite of “died more than 70 years ago” and applies specifically in jurisdictions where the post‑mortem auctoris term exceeds 70 years. ## Key Facts - Duration: 70 years, with the unit “year” and qualifier (date of death of author(s)). - Facet of: post mortem auctoris. - Has effect: works protected by copyrights. - Instance of: heuristic for determination of copyright status of a creator. - Opposite of: died more than 70 years ago. - Different from: born fewer than 70 years ago; 70 years after author's death; died more than 70 years ago; 70 years or more after author(s) death; countries with longer than 70 years pma; countries with 70 years pma; died less than 50 years ago. - Wikidata description: heuristic for determination of "copyright status as a creator" for authors. - Applies to jurisdiction: countries with longer than 70 years pma. - Related concept: heuristic for determination of copyright status of a creator [class] — used as a reference for this heuristic. ## FAQs **What does “died less than 70 years ago” mean in copyright law?** It is a heuristic that evaluates whether an author’s date of death occurred within the past 70 years to decide if their works are still under copyright protection. **Which jurisdictions use this heuristic?** It applies to countries where the post‑mortem auctoris copyright term is longer than 70 years. **What is the opposite heuristic of “died less than 70 years ago”?** The opposite is “died more than 70 years ago,” which indicates that the author’s death occurred beyond the 70‑year threshold. **How does this heuristic differ from “died less than 50 years ago”?** While both refer to recent deaths, “died less than 70 years ago” uses a 70‑year cutoff, whereas “died less than 50 years ago” uses a stricter 50‑year cutoff. **What effect does applying this heuristic have on a work?** If the heuristic is satisfied, the work is considered protected by copyright; otherwise, it may be in the public domain depending on other rules. **To what broader concept is this heuristic a facet?** It is a facet of the post mortem auctoris principle, which links copyright duration to the author’s date of death. **What class does this heuristic belong to according to Wikidata?** It is an instance of the heuristic for determination of copyright status of a creator. ## Why It Matters This heuristic directly influences whether a creator’s works remain under copyright or enter the public domain, affecting access, reproduction, and derivative works. By tying protection to a fixed post‑mortem period, it provides a clear, objective rule for courts, publishers, and digital platforms to assess legal status. In jurisdictions with copyright terms exceeding 70 years, the heuristic prevents premature public‑domain designation, thereby preserving economic rights for heirs and stakeholders. Conversely, its opposite helps identify works that are free to use, supporting education, archival projects, and creative reuse. The rule thus balances private interests with public access in the international copyright ecosystem. ## Notable For - Serves as the specific 70‑year threshold heuristic for copyright status determination. - Defined as the opposite of the “died more than 70 years ago” heuristic. - Explicitly linked to the post mortem auctoris facet in Wikidata. - Directly causes works to be considered protected by copyrights when satisfied. - Applies exclusively to jurisdictions with copyright terms longer than 70 years pma. - Distinguished from multiple related temporal and jurisdictional concepts (e.g., died less than 50 years ago, countries with 70 years pma). - Described in Wikidata as a heuristic for determination of "copyright status as a creator" for authors. ## Body ### Definition and Core Purpose The entity “died less than 70 years ago” is a heuristic used to determine the copyright status of a creator, specifically referenced by property . Its purpose is to test whether an author’s date of death falls within the preceding 70‑year window; if true, the heuristic signals that the creator’s works are likely still under copyright protection. ### Quantitative Property - **Duration**: 70 years. - **Unit**: year. - **Qualifier**: (date of death of author(s)). This quantitative specification is the sole numeric condition that the heuristic evaluates. ### Conceptual Classification - **Instance of**: heuristic for determination of copyright status of a creator. - **Facet of**: post mortem auctoris. - **Has effect**: works protected by copyrights. These classifications place the heuristic within a broader framework of copyright duration rules and indicate its practical outcome. ### Opposition and Differentiation - **Opposite of**: died more than 70 years ago. - **Different from**: - born fewer than 70 years ago - 70 years after author's death - died more than 70 years ago - 70 years or more after author(s) death - countries with longer than 70 years pma - countries with 70 years pma - died less than 50 years ago These relationships clarify what the heuristic is not, delineating its semantic boundaries among similar temporal and jurisdictional concepts. ### Descriptive Metadata - **Wikidata description**: heuristic for determination of "copyright status as a creator" for authors. This description aligns the entity with its function in the Wikidata knowledge base. ### Jurisdictional Scope - **Applies to jurisdiction**: countries with longer than 70 years pma. The heuristic is only relevant in legal regimes where the statutory post‑mortem auctoris term exceeds seventy years; in those locales, it serves as the decisive test for recent deaths. ### Related Concepts - The heuristic is referenced by the class “heuristic for determination of copyright status of a creator,” which acts as a taxonomic parent or reference point in the knowledge model. ### Logical Flow in Application 1. Obtain the author’s date of death. 2. Compute the interval between that date and the present. 3. If the interval is less than 70 years (unit: year, qualifier ), the heuristic returns true. 4. A true result triggers the effect “works protected by copyrights.” 5. If false, the opposite heuristic (“died more than 70 years ago”) may apply, leading to a different copyright status assessment. ### Significance in Copyright Practice By providing a bright‑line rule tied to the author’s lifespan, the heuristic reduces ambiguity in determining whether a work is still under protection. It supports consistent application across databases, rights‑management systems, and legal analyses, especially in regions where copyright terms extend beyond the typical 70‑year benchmark. The rule’s opposition to “died more than 70 years ago” creates a binary partition of the temporal axis, simplifying downstream decisions about public‑domain eligibility, licensing requirements, and digitization projects.
