Extension:Cargo/pt

Cargo é uma extensão para MediaWiki que fornece uma maneira leve de armazenar e consultar os dados contidos nas chamadas para predefinições, como infoboxes. É um conceito similar ao da extensão MediaWiki Semântica, mas oferece um número de vantagens, incluindo facilidade de instalação e uso.

O Cargo armazena todos os seus dados em tabelas de banco de dados, que podem ser colocadas no próprio banco de dados do MediaWiki (o padrão) ou em um banco de dados separado. For the most part, each stored template gets its data stored in a single DB table, with a column for each relevant template parameter. There are a few exceptions to this: the handling of template fields that hold arrays/lists of values, and of fields that hold geographical coordinates, is more complex, due to poor native handling of those data types in most DB systems. And multiple templates can be set to all store their data in one DB table.

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


 * - placed within the part of a template; it defines the schema for a table.
 * - stores one row to a Cargo table; usually placed within the part of a template.
 * - queries one or more Cargo data tables, using SQL components.

The other defined parser functions are:


 * - defines a template as adding rows to a table declared elsewhere.
 * - displays the results of multiple queries in one place.
 * - displays a map showing a single point.
 * - 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.

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

This version of the Cargo extension requires MediaWiki 1.29+.
