  1. PHLAT Living In a Phat Phlatland-Ed Cutrell-

  2. What is PhlatLand Anyway? • Regime Change for Document Storage • Topple the Tyranny of the Hierarchical File System! • Content & Metadata-driven user storage • In PhlatLand, you don’t really care where your stuff lives—you just want to be able to get back to it quickly and easily. • Filter, search, & browse by metadata • Full text search

  3. What’s Wrong With Windows (folders)? • Folders and filenames are just tags with some oppressive properties • C:\My Documents\2002\Talks\CHI2002\Scrolling.ppt • C:\My Documents\Studies\Old Studies\Scrolling\MS4Data & Analyses\MS4Figures.doc • Outlook:\inbox\retired projects\scrolling\RE: Model diffs • D:\Public\Studies\Scrolling\chi2002\ScrollingCHI02[ec].doc • Kill the folder metaphor • Encourages one-object : one-place cognitive model • Instead of “folders” you have “tags” for a more purely semantic organization • Tags CAN be organized hierarchically (but they don’t HAVE to be!)

  4. Tags—What Are They Good For? • Why do people file documents, email, etc.? • Help to find again later • Organize tasks • Keep workspace clean • Organize stuff for other people (knowledge management) • Other reasons (OWA, file sharing) • Other ideas?

  5. Why Keep Hierarchies? • Good organizational structure for knowledge • Lots of knowledge is already so structured • Lots of people are highly trained in using them and tools for navigating them • Maps onto real-world notions of space • Objects live in specific places which can be mapped into other places, etc.

  6. So What’s Wrong With Hierarchies? • Humans do not deal well with sharp category boundaries for knowledge—semantic webs • Lots of garden-pathing, traversing up and down hierarchies to find things. • Cyber space doesn’t need to follow the same rules as space—an object doesn’t really need to “live” anywhere.

  7. Four Main UI Challenges • Organize • Add metadata to stuff • Automatic (user date, relevance, author, etc.) • User-authored tags • How do you create & organize these? Apply them? How do you support & expose hierarchy? • Find • Search/Browse/Identify your stuff • Manage • Must be able to change tags & metadata as cognitive maps & needs change • Spring cleaning, project forks, sharing • How do we add full text (content) search to this?

  8. Three Key Places for Tagging UI • Save • Users are thinking about that object and how it fits in their ontology • Explore • Users need to visualize their ontology and identify the tags to quickly get to their stuff • Best place for tag organization/ management • Open • Basically the same as Explore, but is tuned for a specific task

  9. Related Projects • Grand Central • Focusing on communication now, but encounters many of the same challenges • Szafir (Social Computing Group) • Using WinFS to drive CFD & Explorer • Focused on Explorer & Open experience • Longhorn • UI for everything is still quite tentative, largely metadata driven. WinFS will only include a subset of files on a machine

  10. External Outlook Crawl • 133 Outlook Users (non-MS) • Huge variety in depth & breadth of folder hierarchies • Total branches (folders) • Med=14, Max=810
