libis/cdi-viewer

The CDI-Viewer is a browser-based JSON-LD editor and SHACL validator designed for researchers, data curators, and developers working with semantic web standards. It provides real-time validation and visual editing capabilities for complex JSON-LD structures, originally developed for DDI-CDI metadata but now supporting any RDF vocabulary including schema.org, DCAT, and custom ontologies. The tool eliminates the need for command-line tools or enterprise software by offering an intuitive interface with smart input types, complex object editing, and array management, making it ideal for anyone needing to create, edit, or validate JSON-LD metadata with SHACL constraints.
