CHeCLOUD—the Cultural Heritage Linked Open Data Cloud

Cultural Heritage (CH) data have become increasingly prominent within the Semantic Web, yet dataset discoverability remains limited due to fragmentation across platforms and a lack of a standard platform to give visibility to published data. This demo paper presents the main features of CHeCLOUD (Cultural Heritage Linked Open Data Cloud): the first domain-specific subcloud of the Linked Open Data Cloud specifically devoted to aggregate and enhance access to Knowledge Graphs (KGs) and ontologies related to CH. CHeCLOUD provides a centralized catalog of 192 curated CH KGs and ontologies and computes a FAIR score for each of them, relying on an automatic and periodic assessment of KGHeartBeat. CHeCLOUD currently offers RESTful APIs, metadata browsing, and interactive graph visualizations to support FAIR evaluation. Additionally, CHeCLOUD features a semi-automated submission pipeline that engages users and maintainers through GitHub-based workflows. CHeCLOUD aims to foster reuse, interoperability, and findability within the CH community, while offering a reusable infrastructure to support similar thematic hubs across other domains.
