tagdictionary-SystemIndex

Added smart tag dictionaries in the tagdictionary palette provide support for the system database and system indexing features. Located in the SystemIndexDictionaries folder, the SystemIndex dictionary has a scoped tag to assist with excluding certain objects from system indexing operations.

Once you add the SystemIndex dictionary to your station, you can drop a systemIndex:excluded marker tag on a component and this tag will be implied on all of the component's descendants. In cases where you want to prevent implying this tag on some of the component's descendants, you can drop a systemIndex:included marker tag where necessary and those portions of the tree will not have the systemIndex:excluded marker tag implied and will not be excluded from system indexing.

For stations running prior versions

For stations running on older versions of Niagara, use the SystemIndex dictionary located in the Pre 4.6 folder (shown).

Figure 26. SystemIndex smart tag dictionaries

This pre 4.6 SystemIndex dictionary has a scoped tag rule that can be configured to imply the systemIndex:excluded tag on portions of the station as specified in one or more ord scopes. The pre-4.6 SystemIndex dictionary only implies the systemIndex:excluded tag through ord scopes. The systemIndex:excluded marker tags will not be implied automatically when using the pre-4.6 SystemIndex dictionary.

Name	Value	Description
`systemIndex:excluded`	Marker	When applied to a component and when the SystemIndex dictionary for Niagara is enabled and installed, all descendants will have the same marker tag implied on them (except for descendants of a component with the `systemIndex:included` marker tag applied). This results in these components being excluded from system indexing.
`systemIndex:included`	Marker	When applied to a component, it prevents the `systemIndex:excluded` marker tag from being implied on that component or any of its descendants even if an ancestor of the component has the `systemIndex:excluded` marker tag. This results in the component and its descendants being included in system indexing.
