This extension provides an UI for creating, deleting and viewing relationships between datasets. If the extension is used with ckanext-grouphierarchy-sddi extension, the graphical representation will be in the colours of the groups defined in the ckanext-grouphierarchy-sddi extension. The extension features an interactive Cytoscape.js graph visualization, supports multiple relationship types (parent_of, child_of, depends_on, links_to), and includes multi-language support (German/English).
