The Zettelkasten Navigation plugin offers an innovative way to navigate your digital Zettelkasten using Luhmann-style IDs and keyword indexes. It provides two custom graph views: the 'zk-index-graph-view' and the 'zk-local-graph-view,' which allow for a more structured visualization compared to standard graph views. This plugin brings the organization of Niklas Luhmann's system into Obsidian, helping users visualize chains of thought, starting points, and connections through unique note identifiers. It uses Mermaid.js for graph generation and supports various ID styles, including Luhmann’s Folgezettel and Antinet. By integrating both the IDs and keyword indexes, it enables a more intuitive navigation and retrieval system for complex notes and ideas.
