The scientific exchange correspondence of the Dundo Museum Biology Laboratory (Angola), included in the archive of António de Barros Machado (1912–2002) and Dora Lustig (1907–1986), constitutes a valuable repository of information for the history of contemporary science, particularly in the field of natural sciences—botany, entomology, mammals, ornithology, primates, reptiles, termites, zoogeography, zoology—and of biology. This paper describes the application of the Records in Contexts model to the correspondence collection, with the aim of representing two realities: its production context and the relationships between scientists. The exploration of the model sought to understand its fundamentals and, simultaneously, model the information, starting by identifying the entities, attributes and relations needed for the collection representation scheme. This study resulted in a modelling exercise of the relations between 11 correspondents and the director of the Dundo Museum Biology Laboratory, Barros Machado, regarding the work on the museum collections which culminated in the publication of scientific articles in Publicações Culturais da Companhia de Diamantes de Angola [Cultural Publications of the Diamond Company of Angola]. In the future, it is proposed to apply the same scheme to the description of the remaining scientists in the epistolary collection.

Dundo 博物馆生物实验室（安哥拉）的科学交流通信，包括在 António de Barros Machado（1912-2002 年）和 Dora Lustig（1907-1986 年）的档案中，构成了当代科学史的宝贵信息库，特别是在自然科学领域——植物学、昆虫学、哺乳动物、鸟类学、灵长类动物、爬行动物、白蚁、动物地理学、动物学——以及生物学。本文描述了上下文记录模型在通信收集中的应用，目的是代表两个现实：其生产上下文和科学家之间的关系。对模型的探索试图了解其基本原理，同时对信息进行建模，从识别实体开始，集合表示方案所需的属性和关系。这项研究对 11 名通讯员和邓多博物馆生物实验室主任 Barros Machado 之间的关系进行了建模练习，该练习涉及博物馆藏品的工作，最终在Publicações Culturais da Companhia de Diamantes de Angola [安哥拉钻石公司的文化出版物]。将来，建议将相同的方案应用于书信集中其余科学家的描述。
