Fallen London Wiki:Semantic Mediawiki/Data Model

From Fallen London Wiki

This page explains how gameplay is modeled by Semantic MediaWiki properties on the Wiki. Some of these properties are in active use by the Wiki, while others are planned or in the progress of deployment. This page should get a general idea of what's currently possible, or will be possible in the near-ish future.

This list covers the major properties, but is not exhaustive. There are a number of minor properties with niche uses.

General Properties[edit]

These properties can apply to almost any type of article page.

Property:Has icon
Points to the image file for the icon. Actively used for {{IL}} and {{I}}.
Records the ID of the item. Widely deployed.
Property:Has Game Type
Denotes what type of game object the page is for, e.g. "Quality" or "Social Action." The list of available actions is available at Smw allows list Has Game Type.
Property:Is retired
Property:Is guide for
Used by Guides to describe the content they cover. Used by many templates to automatically add guide links with {{HasGuide}}.

Display Properties[edit]

These properties contain formatted wikitext intended for direct display on the Wiki. They generally aggregate data from several other properties or pages, making the display of such data simpler and more efficient. They can be thought of as "cached" query results.

Property:Has restrictions
A list of "tags" that denote restrictions on an action or quality, e.g. "FATE HALLOWMAS."
Property:From message
A description of where to find the game asset in question, e.g. "a Storylet in Spite" or "an Action from A commotion above!, a Card in Your Lodgings." Combines data from Has Game Type and From Card/Storylet.

Items and Qualities[edit]

Property:Has cap
Qualities (or items) with a hard cap. In active use by {{Gain}} to annotate gain messages.


These properties are in active use by {{Item}} to display best-in-slot annotations, and by {{ItemList}} to generate item listings such as those at Hats.

Property:Has effect (Modifies quality, Modifies by)

Stores price and shop from which an item can be bought.
Property:Sells for (for Price many of a Currency to a Market)
