SchemaLink is a web application designed to assist LinkML developers in creating and curating schemas.

SchemaLink builds upon the functionality of Neo4j’s Arrows, a web tool for drawing and editing property graphs. SchemaLink extends its capabilities to focus on LinkML schemas. Nodes represent classes in the schema, edges define relationships between classes. Users can easily add, remove, or update schema items and adjust their properties through an intuitive interface.
