Filesystem as Database

BeOS contacts

Here's the Contacts editor on Haiku, BeOS' spiritual successor which is actually just a file manager window with a specific set of attributes displayed.

  • filesystem could "just" store data blobs with user-defined metadata and custom (materialized) views
  • querying could be done one level "higher" - no need for folders and files
  • folder and file UI could be just one of the views on top of that storage
    • I could as easily ask for last n images, everything linked to idea of memex etc...
    • spreadsheet-like interface could be interesting as well here
    • this gets even more exciting when combined with Plan 9 vision where everything is a file
  • computation as database retrieval (also viewing and filtering)
