Archives are facing numerous challenges. On the one hand, archival assets are evolving to encompass digitized documents and increasing quantities of born-digital information in diverse formats. On the other hand, the audience is changing along with how it wishes to access archival material. Moreover, the interoperability requirements of cultural heritage repositories are growing. In this context, the Portuguese Archives started an ambitious program aiming to evolve its data model, migrate existing records, and build a new archival management system appropriate to both archival tasks and public access. The overall goal is to have a fine-grained and flexible description, more machine-actionable than the current one. This work describes ArchOnto, a linked open data model for archives, and rules for its automatic population from existing records. ArchOnto adopts a semantic web approach and encompasses the CIDOC Conceptual Reference Model and additional ontologies, envisioning interoperability with datasets curated by multiple communities of practice. Existing ISAD(G)-conforming descriptions are being migrated to the new model using the direct mappings provided here. We used a sample of 25 records associated with different description levels to validate the completeness and conformity of ArchOnto to existing data. This work is in progress and is original in several respects: (1) it is one of the first approaches to use CIDOC CRM in the context of archives, identifying problems and questions that emerged during the process and pinpointing possible solutions; (2) it addresses the balance in the model between the migration of existing records and the construction of new ones by archive professionals; and (3) it adopts an open world view on linking archival data to global information sources.

翻译：档案领域正面临诸多挑战：一方面，档案资源持续演进，涵盖数字化文档及日益增长的各类原生数字信息；另一方面，用户群体及其对档案资料的获取方式也在发生变化。与此同时，文化遗产机构间的互操作性要求不断提高。在此背景下，葡萄牙档案馆启动了一项前瞻性计划，旨在改进数据模型、迁移现有记录，并构建适应档案管理任务与公众访问需求的新型档案管理系统。其核心目标是建立比现有系统更细粒度、更灵活且更具机器可操作性的描述体系。本文介绍了面向档案的开放链接数据模型ArchOnto，以及基于现有记录自动填充该模型的规则。ArchOnto采用语义网方法，集成CIDOC概念参考模型与附加本体，致力于实现与多实践社区所管理数据集之间的互操作性。我们利用所提供的直接映射规则，将现有符合ISAD(G)标准的描述迁移至新模型，并通过涵盖不同描述层级的25条记录样本验证了ArchOnto的完整性和数据兼容性。本研究尚在进行中，其原创性体现在：（1）作为首批在档案领域应用CIDOC CRM的尝试之一，识别了实施过程中的问题与挑战并提出解决方案；（2）在模型设计中平衡了档案专业人员对现有记录的迁移需求与新记录的构建需求；（3）采用开放世界视角，将档案数据与全球信息源进行关联。
