Synchronizing

The second useful capability I wanted this solution to support is the ability for various applications I use to synchronize their data with a single ‘master’ copy. That allows multiple individuals to read, edit and update information and ensure everyone has easy access to the latest version. For example, in my article on setting up a laptop for use after a disaster I mentioned the use of tools like Obsidian and/or Joplin for managing things like intelligence information, basic note-taking, inventory management, etc. Both of these applications support the ability to synchronize changes utilizing a protocol called ‘Web Distributed Authoring and Versioning’, better known as WebDAV, so if I update inventory data on my network-connected laptop I can see those updates on my mobile phone the next time I open the app and synch. Calendars and tasks are another example, and there’s an extension to WebDAV called CalDAV that is specifically designed for synchronizing calendar and task information. That way, if I add an appointment or create a task on my phone it’ll automatically synchronize to the master copy on the router so it’ll show up in my laptop’s calendar/task list. Mozilla Thunderbird calendar has support for CalDAV built in.
