In the exploration of familial and social structures, accurately representing kinship relationships is crucial for a comprehensive understanding of human societies. Traditional methods of documenting these relationships often involve complex diagrams or extensive genealogical records, which can be cumbersome to interpret and manage. Recognizing the need for a more streamlined approach, this paper introduces a novel system for the encoding of kinship relationships: the “Fcodes”. The primary objective of this system is to provide a straightforward, efficient, and adaptable approach to representing complex kinship networks in a manner that is easily understandable and accessible to both humans and computers.
