Figure 11.   Example tag rule

The smart tag dictionary automatically applies the implied tags and relations to objects. Technically, implied items (the implied tags and implied relations) are never added to the station, and the station size is not increased as a consequence.

One example of a smart tag dictionary is the Niagara tag dictionary, whose namespace (n:) is the ‘n’ character followed by a colon. It is included by default in all stations created using the New Station Wizard.

Another example is the Haystack tag dictionary, indicated by hs: namespace. This dictionary is available from the haystack palette which is included in the Niagara installation. The Haystack dictionary is a result of the work of the Haystack community hosted on http://project-haystack.org.
