Understanding the transfer and persistence of different types of trace evidence between different donor and receiving surfaces under specific conditions, circumstances and alleged competing defence and prosecution hypotheses is a significant need. Acquiring such a knowledge base enables hypothesis testing to be undertaken more readily and with greater confidence. A longstanding goal has been to develop a unified approach to transfer and persistence studies which are fit for purpose but also scalable. Here we propose a low cost, universal experimental protocol using a recognised and well researched proxy material for the development and aggregation of ground truth transfer and persistence data at scale. We also propose and provide the tools to enable the creation of an open source and open access data repository of experimental data to act as a resource for practitioners and researchers in addressing transfer and persistence questions.
了解在特定条件、情形以及控辩双方提出的相互竞争的假设下，不同类型微量证据在不同供体和受体表面之间的转移和留存情况，是一项迫切需求。获取这样一个知识库能够使假设检验更容易且更有信心地进行。一个长期目标是开发一种统一的方法来进行转移和留存研究，这种方法既要适用又要可扩展。在此，我们提出一种低成本的通用实验方案，使用一种经过认可且深入研究的替代材料，以便大规模开发和汇总真实的转移和留存数据。我们还提出并提供工具，以创建一个实验数据的开源且开放获取的数据库，作为从业者和研究人员解决转移和留存问题的资源。
