Being relatively new to EA, I have not found a means to gathering data into a 'data dictionary'. What this is supposed to do for a user, at a minimum, is to allow input of a term such as a variable name, its data type (date, text, integer, etc.), how it is used in the context of a modeling element, and who created it.
Since I'm new to EA, I wouldn't want to have to write an automation script to gather this data, so if anyone knows of a work-around, or the actual existence of this type of feature, please let me know. Thanks! :-/
