Editing Importance Extension

[[File: Wiki Navy.png|right]]
The [[Importance Extension]] or [[Ix]] is a gross measure of a [[world]]'s overall interstellar importance in generalized terms.
* It represents a very gross estimate of a [[mainworld]]'s socioeconomic value.
* While much of the value is in raw economic terms, other factors could influence the rating including starport size, political importance, desirable astrographic locations (...[[communication route]]s as opposed to [[trade route]]s), political importance, a high planetary habitability rating, or even cultural factors.

== Description ([[Specifications]]) ==
The Importance Extension is abbreviated [[Ix]] and written in braces ({+/- N}). It is a decimal integer (positive, negative, or zero) ranking the importance of the world within a region.

On this case, the importance of the [[mainworld]] is ranked within the subsector socio-economy, which is the basic level of functionality within Charted Space. 

=== Importance Extension Basic Parameters ===
* [[Capital]] (Political Prestige)
* [[Desirability]] (Planetary Habitability)
* [[Starport]] (Access for Interstellar Communications & Trade)
* [[Trade Route]]s (...established Interstellar Trade)
* Presence of [[Naval Base]], [[Scout Base]], and/or other bases

=== Importance Extension Parameter Explication ===
* ''Importance Extension''
** ''(The Importance Extension ([[Ix]]) ranks [[world]]s within an astrographic region. It governs the locations of [[capital]]s and [[trade route]]s.)''

== History & Background ([[Dossier]]) ==
The [[Office of the Emperor]], the [[Imperial Bureaucracy]], the [[Imperial Interstellar Scout Service]], the [[Travellers' Aid Society]], the [[Merchant Service]], the [[Educational Institute]]s, and many other interstellar [[organization]]s use this data for [[governance]], [[interstellar economy]], world surveys, and other necessary tasks.

Such data drives [[Charted Space]].

Today's [[IISS]] ''Importance Extension'' was developed from an earlier [[metric]] known as the [[Eaglestone Trade Index]].
