A data transmission dictionary is provided, which is adapted for use by a co mputer system for encoding, storing, or retrieving hierarchically related data transmissio n information. The dictionary is comprised of a group of one or more computer searchable defini tion trees relating to transmission information of the computer system. The trees are d erived from a first definition group which includes characteristics of commands, replies or data usable by the computer system. The characteristics include structure and value prop erties and restrictions, if any, applying to the commands, replies or data. Each tree r epresents, respectively, a definition of a the command, reply or data to which it relat es. Each tree includes a root node identified by name, eg. a codepoint. The root node incl udesinformation describing the type of definition tree c oncerned (i.e. whether it relates to a command, reply or data), and may include one or more internal or terminal de scendant 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 requireme nts relating to transmission information represented by the nodes.
