The Vika Sync plugin integrates Obsidian with Vika, a cloud-based database software, allowing you to sync note data seamlessly between the two platforms. It supports creating, updating, and deleting records in Vika, as well as recovering notes from Vika into your vault. The plugin allows customization of fields for uploading data from Obsidian's frontmatter to Vika, and downloading data from Vika back to Obsidian. You can synchronize individual notes, entire folders, or the entire vault. It also includes default fields for integration, such as title, ID, tags, aliases, and backlinks.
