Window Per Task Mumble mumble blah mumble mumble blah blah blah blah mumble blah mumble Save! Open - Should a page be found to be incomplete or poorly organized, any reader can edit it as they see fit.! Incremental - Pages can cite other pages, including pages that have not been written yet.! Organic - The structure and text content of the site is open to editing and evolution.! Mundane - A small number of (irregular) text conventions will provide access to the most useful page markup.! Universal - The mechanisms of editing and organizing are the same as those of writing so that any writer is automatically an editor and organizer.! Unified - Page names will be drawn from a flat space so that no additional context is required to interpret them.! Precise - Pages will be titled with su!cient precision to avoid most name clashes, typically by forming noun phrases.! Tolerant - Interpretable (even if undesirable) behavior is preferred to error messages.! Observable - Activity within the site can be watched and reviewed by any other visitor to the site.! Convergent - Duplication can be discouraged or removed by finding and citing similar or related content.! Overt - The formatted (and printed) output will suggest the input required to reproduce it.

5 Objects May Be Missing Objects Trail Location History Servers Resolve Duplicates Server Heuristics Connection - Chooses when to open, accept and close connections. Guided largely by trail climbing of interesting objects and average channel performance. Allocates sockets, total bandwidth, and processing time devoted to transmission. Distribution - Chooses which objects to distribute through each open channel. Guided by authority, apparent interest from hosted application, and interest shown by peer servers. Allocates channel bandwidth to individual objects. Preservation - Chooses which objects will be kept in the server. Guided by authority, network and application interest, connection behavior and available space. Adaptive Federation New Framing Adaptive Federation Left POV Right POV
