Relationship Model for Modeling Relationships Between Equivalent Objects Accessible Over a Network

A method performed by at least one computer processor executing computer program instructions tangibly stored in a computer-readable medium, the method comprising:

• (A) obtaining, over a network, first data maintained by a first resource;
• (B) obtaining, over the network, second data maintained by a second resource;
• (C) identifying a first portion of the first data, wherein the first portion relates to a first object;
• (D) identifying a second portion of the second data, wherein the second portion relates to a second object;
• (E) determining whether the first object and the second object are equivalent to each other;
• and
• (F) if it is determined that the first object and the second object are equivalent to each other, then:
• (F1) storing an indication of a relationship between the first portion and the second portion remotely from the first and second resources.
