Copyleftkrav

Copyleftkrav is a hypothetical licensing concept that combines copyleft principles with a predefined set of mandatory obligations, referred to as krav. In this model, a work released under copyleftkrav carries a fixed bundle of requirements that downstream recipients must meet when redistributing or modifying the work. The aim is to provide a clear, standardized framework of conditions that accompanies every copy and derivative, ensuring continued access to the source and the rights to reuse.

Core ideas include: guaranteeing access to source code for modified versions, requiring preservation of license notices and attribution, and mandating that derivatives be released under compatible terms. The krav may be enumerated in a separate document or embedded within the license text, and they are intended to travel with the work through all distributions. Supporters argue that a formal krav helps reduce ambiguity, strengthens user freedoms, and improves interoperability by making obligations explicit.

Scope and applications are typically discussed in software contexts, but the concept could extend to hardware designs, documentation, and data. A copyleftkrav framework would need to address practical issues such as license compatibility, enforcement, and cross-border legal interpretation. It would also raise questions about compatibility with existing licenses, dual licensing strategies, and the potential for increased complexity in compliance.

Criticism often centers on increased complexity, potential friction with existing open licenses, and the risk of fragmented ecosystems if different krav sets emerge. Critics also warn that rigid krav could deter adoption or create uncertainty in international jurisdictions.
