  • Stand-off annotations are pointers into the XML document
  • Documents form a tree
  • 6 more annotations...
  • • independent of the XML document structure
    • text documents
    • represent the rich text messages in a wavelet (casually known as blips)
    • data documents
    • are typically invisible
    • for example, tags

  • Stand-off annotations are pointers into the XML document and are independent of the XML document structure. They are used to represent text formatting, spelling suggestions and hyper-links.
  • There are currently two types of documents: text documents, used to represent the rich text messages in a wavelet (casually known as blips), and data documents which are typically invisible to the user (for example, tags).
  • 8 more annotations...
  • • The unit of sharing is a wavelet. In the first version of this protocol, all participants on a wavelet have full access to modify the contents and participant list of that wavelet.

    • Heterogeneous sharing within a wave is achieved by having differing participant lists on wavelets within the wave. Currently, the two primary uses of this are user-data and private replies.

    • the wavelet state to be consistent throughout the system
    • The client is responsible for ordering the operations that were received from the server before applying them to its local copy of the wavelet copy.
    • according to a version number provided by the server.
    • wavelets are grouped into a "wave-view", which is the set of wavelets on a wave visible to a given user.
    • A snapshot - the serialized state of the wavelet
    • When client-server communications fail, the client and server need to agree on a common state of the wavelet upon reconnecting.

  A "wave" is equal parts conversation and document ... Google Wave is also a platform with a rich set of open APIs... Each wave has a globally unique wave ID and consists of a set of wavelets. A wavelet has an ID that is unique within its containing wave a
