Cargo は MediaWiki 拡張機能であり、テンプレート呼び出しに含まれるデータを格納したり、データのクエリを実行したりできる軽量な方法を提供します。 概念は Semantic MediaWiki 拡張機能に似ていますが、インストールの容易さや使いやすさなど、多くの利点があります。

Cargoはデータをデータベース テーブルに格納します。そのデータベース テーブルは(デフォルトで)MediaWikiのデータベース、または別のデータベースに配置できます。 ほとんどの場合は、格納されるテンプレートのデータは独自のDBテーブルに保存されます。そのなかの列は一つのテンプレート パラメータに関連付けられます。 しかし、例外も存在します。多数のDBシステムでは値の配列・リストがあるテンプレート フィールドと地理座標があるフィールドをうまく処理できないため、これらのデータの処理はより複雑になります。 複数のテンプレートのデータは、単一のDBテーブルに保存できます。

The extension defines a number of parser functions; these three are the most important:

  • #cargo_declare - placed within the ‎<noinclude> part of a template; it defines the schema for a table.
  • #cargo_store - stores one row to a Cargo table; usually placed within the ‎<includeonly> part of a template.
  • #cargo_query - queries one or more Cargo data tables, using SQL components.

The other defined parser functions are:

  • #cargo_attach - 他の場所で宣言されたテーブルに行を追加するようにテンプレートを定義します。
  • #cargo_compound_query - displays the results of multiple queries in one place.
  • #cargo_display_map - displays a map showing a single point.
  • #recurring_event - prints out the dates for a recurring event; for use by #cargo_store.

Cargo also defines various interfaces for viewing and drilling down through this stored data. As such, it adds the following special pages:

  • Special:CargoQuery
  • Special:CargoTableDiagram
  • Special:CargoTables
  • Special:Drilldown

Cargo has been tested, and works, with the MySQL and PostgreSQL database systems. In theory, it also supports SQLite, but it has not been well-tested with SQLite and may not work.

This version of the Cargo extension requires MediaWiki 1.35+.

Click through the pages in the navigation bar above to learn more about Cargo, how it works, how to use it, and how to install it.

設定

Below are Cargo's global configuration settings along with their default values.

To configure Cargo to use a separate database instead of the MediaWiki database, the following settings are provided:

Separate database configuration settings
Setting Default Description
$wgCargoDBtype null Database type.
$wgCargoDBserver null Host name or IP address of database server.
$wgCargoDBname null Name of the database.
$wgCargoDBuser null Database username.
$wgCargoDBpassword null The password for $wgCargoDBuser.
$wgCargoDBprefix null Database table name prefix.
$wgCargoDBRowFormat null Data base row format.

For character configuration as related to numbers, the following configuring settings are provided:

Character configuration settings
Setting Default Description
$wgCargoDecimalMark . Decimal character for numbers.
$wgCargoDigitGroupingCharacter , Thousands digit separator.

The remaining global configuration settings are as follows:

Setting Default Description
$wgCargoAllowedSQLFunctions [] Sets allowed SQL functions. See Using SQL Functions for defaults.
$wgCargoRecurringEventMaxInstances 100 The number of max instances to store for recurring events with no set end date.
$wgCargoDefaultStringBytes 300 The default number of characters for fields of type Page, String, Wikitext string, File, URL, Email
$wgCargoDefaultQueryLimit 100 Number of results to show for #cargo_query if no limit is set
$wgCargoMaxQueryLimit 5000 The maximum allowed number of results for #cargo_query
$wgCargo24HourTime false If true uses 24-hour time for Datetime field types.
$wgCargoDefaultMapService OpenLayers Sets the default map service to Google Maps, if set to googlemaps, to Leaflet if set to leaflet, and to OpenLayers if set to openlayers.
$wgCargoGoogleMapsKey null API key for Google Maps, for the googlemaps display format.
$wgCargoMapClusteringMinimum 80 If the number of map points displayed is greater than the value of $wgCargoMapClusteringMinimum, the map displays the locations in "clusters" instead of individual points, for readability. If set to a very high number, does not display clustering.
$wgCargoDrilldownUseTabs true Displays Special:Drilldown table names as tabs at the top instead of a vertical list at the side.
$wgCargoDrilldownSmallestFontSize -1 If set to a positive number, sets the smallest font size, in pixels, for a tag-cloud-style display of filter values.
$wgCargoDrilldownLargestFontSize -1 If set to a positive number, sets the largest font size, in pixels, for a tag-cloud-style display of filter values.
$wgCargoDrilldownMinValuesForComboBox 40 Sets the minimum number of values before their display is converted to a combo box, instead of individual links.
$wgCargoDrilldownNumRangesForNumbers 5 For fields/filters of type Integer or Float, specifies the number of "buckets" into which values are divided.
$wgCargoMaxVisibleHierarchyDrilldownValues 30 If set to a positive integer, specifies the maximum number of values shown at a time for any hierarchy field (All the top-level values are shown irrespective of this value). The values are hidden beyond a certain depth of the hierarchy such that the count of total visible values is at most this number.
$wgCargoTablesPrioritizeReplacements false If true, all tables having a replacement appear at the top of the Special:CargoTables page, instead displaying them in alphabetical order.
$wgCargoPageDataColumns [] The set of fields to store in the _pageData Cargo table. See Storing page data .
$wgCargoFileDataColumns [] The set of fields to store in the _fileData Cargo table. See Storing file data .
$wgCargoHideNamespaceName [6] Array of namespaces to hide from query results.
$wgCargoLegacyNullLuaFieldsAsEmptyString false Null results to the Lua Cargo query function should return as string rather than nil. This allows you to rollback a breaking change from early 2022. New wikis created after this time should not enable this.
$wgCargoStoreUseTemplateArgsFallback true Enable the behavior that looks for template arguments that match the template's declared table to fill columns.
