Cultural gems is a web application conceived by the European Commission's Joint Research Centre (DG JRC), which aims at engaging people and organisations across Europe to create a unique repository of cultural and creative places. The main goal is to provide a vision of European culture in order to strengthen a sense of identity within a single European cultural realm. Cultural gems maps more than 130,000 physical places in over 300 European cities and towns, and since 2020 it also lists online cultural initiatives. The new release aims, among other, to increase the interoperability of the application. At this purpose, we provide an overview on the current development of an ontology for Cultural gems used to map cultural heritage in European cities by using Linked Open Data (LOD) standards, and making the data FAIR, that is Findable, Accessible, Interoperable, and Reusable. We provide an overview of the methodology, presenting the structure of the ontology, and the services and tools we are currently building on top.

翻译："文化瑰宝"是由欧盟委员会联合研究中心（DG JRC）开发的一款网络应用程序，旨在吸引欧洲各地的民众和组织共同创建独特的文化创意场所知识库。其主要目标是通过展示欧洲文化图景，强化"欧洲文化共同体"中的身份认同感。该应用已收录逾300个欧洲城镇的13万多个实体文化场所，并自2020年起新增线上文化项目名录。新版应用的核心目标之一在于提升互操作性。为此，我们概述了目前为"文化瑰宝"开发的本体工程——该本体遵循关联开放数据标准对欧洲城市的文化遗产进行建模，使数据符合FAIR原则（即可发现、可访问、可互操作、可复用）。我们介绍了方法论框架，呈现了本体的结构体系，并阐述了正在基于该本体构建的服务与工具。
