The sustainability of digital research outputs, particularly in the humanities where these frequently comprise archives of digital cultural heritage material, has always offered a challenge to the researchers and institutions who have responsibility for them. The amount of upfront care, effort, and funding that goes into developing a research project during the active (and funded) research phase is rarely replicated within the post-project maintenance and curation of the delivered digital assets or archives. What often defines the sustainability of a research project and its archive is a combination of research method and expected life span for the digital collection. Innovation in research data design is often at the expense of its longevity. But this does not need to be so. The tradeoff between longevity and functionality is a false dichotomy. Yet what is clear is that care and consideration in planning the research data storage or archive for a project can make a big difference. A data management plan that meets grant funder requirements is asked for for many research projects, but it is more than simply a funding document. Good research data management ensures that outputs are available online for years to come and available for future research and innovation. This article offers a practical insight to the methods being employed at the University of Oxford to support Digital Humanities scholars (and beyond) safeguard their digital legacy for future generations.

数字研究成果的可持续性，特别是在人文学科领域，这些成果通常包含数字文化遗产材料的档案，一直为负责这些成果的研究人员和机构提出了挑战。在主动（和资助）研究阶段开发研究项目所投入的前期关注、努力和资金量很少在项目后维护和交付的数字资产或档案的管理中得到复制。通常定义研究项目及其档案的可持续性的是研究方法和数字馆藏的预期寿命的结合。研究数据设计的创新往往是以牺牲其寿命为代价的。但事实并非如此。寿命和功能之间的权衡是错误的二分法。然而，显而易见的是，在规划项目的研究数据存储或归档时的谨慎和考虑可以产生很大的影响。许多研究项目都需要满足资助者要求的数据管理计划，但这不仅仅是一份资助文件。良好的研究数据管理可确保输出在未来几年内可在线获取，并可用于未来的研究和创新。本文提供了牛津大学为支持数字人文学者（及其他学者）为子孙后代保护他们的数字遗产而采用的方法的实用见解。
