The presented method reveal that the use of RDF facilities together with AFF4 flexible metadata and its distributed evidence management is a strong tool to improve the chain of custody reliability, especially because this system should be based on real world transducers, such as GPS, motion detectors, environmental recorders, time-stamp generators, biometric identification and digital signatures. The proposed method is, as an indirect consequence, an essential to the design and development of a really functional distributed evidence management and chain of custody control system. The solution should also adhere to the semantic web layered architecture. This approach complements previous work led by others researchers as described imnrovine chain of custadv Starting from these models, the RDF implementation is represented, in a free form, as follows:
