Resolving a query received from a first node in a network includes accepting, by a second node in the network, ownership of the query from the first node, receiving, at the second node, an identification of a third node in the network, wherein the identification is received from a user of the second node and the user of the second node believes that a user of the third node has information necessary to resolve at least part of the query, and transferring, by the second node, ownership of the at least part of the query to the third node, wherein the accepting, the receiving, and the transferring dynamically generates a data structure that traces a propagation of the query, and the data structure is accessible to an origin of the query.
