Abstract:

In a network, a query originator injects queries of network devices into the network at a query node using query messages. The network transports the query messages to the network devices, or to network nodes at which queries about the network devices can be answered. Query responses from the network devices or network nodes are directed through the network to a collection node or nodes. As an internal network node receives multiple query responses from network devices, the internal network node might aggregate, as needed, the multiple query responses into an aggregated query response that preferably occupies less bandwidth than the aggregated multiple query responses. Where the result desired at the collection node is a computed function of the multiple query responses, the computed function can be performed at each internal network node on the multiple query responses received at that node, thus distributing the computation needed to form a collected response to the query. Queries might request real-time or non-real-time responses and queries might request one response, periodic responses or one response for each occurrence of an event. The internal network nodes might store lookup tables, or access a centralized lookup table, that specify details of queries, thus obviating the need for each query message to carry all of the necessary details of the query.

Abstract:

A large open database of information has entries for commonly understood data, such as people, places and objects, which are referred to as topics. The database has a type system and contains attributes and relationships between topics. The invention also comprises a powerful query language and an open API to access the data and a website where contributors can update the data or add new topics and relationships. The elements of the invention comprise a scalable graph database, a dynamic user contributed schema representation, a tree-based object/property query language, a series of new Web service APIs, and set of AJAX dynamic HTML technologies.
