A system and method for formatted inter-node communications over a computer network comprises a transmitting node transmitting a message in a format acceptable to the receiving node. Message templates are created by the receiving node and then stored in a repository accessible by both the transmitting node and the receiving node. The message templates are identified by a digital ID tag and comprise a pattern of labeled fields visible to the transmitting node and accessible for message input by the transmitting node.
