"Traceability systems in the CITES context: A review of experiences, best practices and lessons learned for the traceability of commodities of CITES- listed shark species" (2015) by Victoria Mundy and Glenn Sant is really interesting overview of approaches to traceability with multiple examples (caviar, timber, crocodile skins) giving you a good scope about implementation details about various traceability systems.
