This special theme examines the dynamic relationships between production, availability, and usage of Big Data, laying out a research agenda for digital heritage at the time of the ‘data turn’. Over the past 15 years, a proliferation of heritage data has been generated by ‘ecosystems of distributed practices’ enacted by the co-working of bodies, cultural identities, organisational workflows, software, application programming interfaces, etc. The authors of research articles and commentaries in this collection explore the three macro-dimensions along which we can map transformations of and by heritage in Big Data ecologies: (a) ontologies or heritage as datified resources, (b) interactions and (c) methodologies and epistemologies.

这个特殊的主题考察了大数据的生产、可用性和使用之间的动态关系，在“数据转向”时期为数字遗产制定了研究议程。在过去的 15 年中，由机构、文化身份、组织工作流、软件、应用程序编程接口等共同制定的“分布式实践生态系统”产生了大量遗产数据。本集中的评论探讨了三个宏观维度，我们可以沿着这些维度绘制大数据生态中遗产的转换和通过遗产的转换：(a) 作为数据化资源的本体或遗产，(b) 交互和 (c) 方法论和认识论。
