<p>This article proposes a general taxonomy of artefacts, modeled on the Linnaean hierarchy of biological classification but grounded in criteria specific to material culture and technical kinds. It begins with a philosophical analysis of artefacts as material–intentional products of human design, emphasizing their decisive differences from living organisms and the consequent need for a distinct classificatory framework. Based on this foundation, the paper defines eight nested ranks (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species) intended to organize technodiversity by progressively specifying (i) ontological constitution, (ii) large-scale structural form, (iii) operative mechanisms, and (iv) technical functions, down to concrete designs and models. The proposed system is guided by five methodological principles: ontological hierarchy, exclusivity and dominance, non-redundancy, universality and completeness, and dynamic revision. These principles constrain demarcation and facilitate cross-domain applicability. An illustrative example within the phylum of physical artefacts demonstrates the transition from broad categories to detailed identification of specific artefact types and models. The article concludes that a Linnaean-inspired taxonomy offers a unified conceptual framework for integrating diverse catalogues, enhancing artefact traceability, and establishing a foundation for future phylogenetic analyses of sociotechnical change in material culture.</p>
