Traditional Knowledge is the evolving body of knowledge, practices, skills, innovations, and cultural understanding developed by Indigenous peoples over generations. It is closely related to Traditional Cultural Expressions and genetic resources, and its use raises issues of consent, sovereignty, attribution, and protection.
Widely understood as "the ever-evolving body of intellectual knowledge cultivated by [Indigenous Peoples]," Traditional Knowledge (TK) often involves the cultural skills, know-how, and other innovations developed over generations (World Intellectual Property Organization, p.10). Note that Traditional cultural expressions (TCEs) and genetic resources (GR) are related to TK.
