Presentation Transcript
last meeting
Last Meeting…
  • Mentioned about tags on files.
  • Database-based file systems
    • Instead of, or in addition to, hierarchical structured management, files are identified by their characteristics, like type of file, topic, author, or similar rich metadata.
  • Simple solution: soft link
tag2find
tag2find
  • tag2find helps users to find everything on their desktop by simply using tags.
    • a tag is simply a label or keyword that describes the file for making it easer to find.

short summary
Short Summary
  • To cope with current hierarchy based file system.
    • Most tag file systems are layers between user and underlying file system.
    • Tags are stored independently with file.
  • Current tag file system works on single machine.
    • what if we apply tags to cloud?
