Relation Definitions

Tag Dictionaries often contain a collection of Relation Definitions (shown in the following image) which are standardized Relation Id's with semantic meaning for a given domain or namespace. These relation definitions come into play when adding a relation to a component. In the Relation dialog, your choices are limited to the relations that are defined in the any of the Tag Dictionaries on your system.
