摘要： The present invention discloses an architecture for document archival built on network-centric groupware such as Internet standards-based messaging. Archiving and retrieving and classifying documents into meaningful collections is accomplished in a manner similar to sending email to recipients, retrieving messages from folders, and classifying messages into folder hierarchies. In the simplest scenario, if saveme.com is the archiving server's name, then sending an email to abc@saveme.com will cause the contents of the email message to be archived in the abc mailbox. The archived documents may be automatically stored in jukeboxes of non-tamperable media such as Write Once Read Multiple (WORM) Compact Disks (CD), which provide high storage capacity, low cost compared to magnetic disks, random data access, and long-term stability. The present invention leverages existing messaging infrastructures, and the resulting environment is not intrusive, easier to administer, and easier to deploy than conventional dedicated document archival systems.

摘要： A method for transforming multi-dimensional data points into 1-dimensional values which are stored in a 1-dimensional index structure is disclosed. The data space is divided into a first plurality of pyramids each having a center point of the data space as a top and a (d-1) dimensional surface of the data space as a base, wherein the first plurality of pyramids is equal to twice the number of dimensions of the data space. Each pyramid is then divided into a second plurality of partitions. A Pyramid-value for each partition is then computed. Finally, each partition is stored in the index structure using the Pyramid-value as an index key.
