A data transmission dictionary is provided, which is adapted for use by a computer system for encoding, storing, or retrieving hierarchically related data transmission information. The dictionary is comprised of a group of one or more computer searchable definition trees relating to transmission information of the computer system. The trees are derived from a first definition group which includes characteristics of commands, replies or data usable by the computer system. The characteristics include structure and value properties and restrictions, if any, applying to the commands, replies or data. Each tree represents, respectively, a definition of a the command, reply or data to which it relates. Each tree includes a root node identified by name, e.g., a codepoint. The root node includes information describing the type of definition tree concerned (i.e., whether it relates to a command, reply or data), and may include one or more internal or terminal descendant nodes. These nodes represent components of the definition represented by the tree. The descendent nodes include level information describing the level of the node within its tree. The nodes may include attribute information, and may include value requirements relating to transmission information represented by the nodes.

Dictionary for encoding and retrieving hierarchical data processing

A method of creating a data transmission dictionary by deriving a group of one of more computer searchable definition trees from a first definition group of nodes defining portions of commands, replies, or data usable by a computer system, compacting each of the nodes by retaining only information necessary for the processing of data transmission streams according to the definition trees; assembling each definition tree by sequencing the compacted nodes in a linear form, starting with the root node of each of the definition trees, by placing information included in each compacted node in a resulting implemented dictionary; and by assembling each child node in the resulting implemented dictionary and assembling each of the child's child nodes in turn. The process of assembling a terminal node involves placing information included in the terminal node in the resulting implemented dictionary.
