The KOI Sync plugin integrates Obsidian with the KOI ecosystem, allowing users to synchronize knowledge objects from a remote KOI-net node. Designed primarily for the Telescope project, it listens for RID events and converts raw JSON data into human-readable markdown using a customizable Handlebars template. The plugin enables automatic updates to maintain a local cache of synchronized data and offers manual resynchronization when needed. Users can configure API access to interact with a self-hosted KOI-node, ensuring controlled data flow without sending information to external servers. This tool is useful for those leveraging the KOI knowledge network within their Obsidian workflow.
