  14. Wiki Design Principles • 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. • Overt - The formatted (and printed) output will suggest the input required to reproduce it. • 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 sufficient 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. http://c2.com/wiki?WikiDesignPrinciples

  16. Wikipedia My question, to this esteemed Wiki community, is this: Do you think that a Wiki could successfully generate a useful encyclopedia? -- JimboWales Yes, but in the end it wouldn't be an encyclopedia. It would be a wiki. -- WardCunningham http://c2.com/cgi/wiki?WikiPedia

  17. Representation & Communication Encyclopedia Wikimedia Do not think of Wikipedia as justan encyclopedia

  28. 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.
