The External Data extension allows MediaWiki pages to retrieve, filter, and format structured data from one or more sources. These sources can include external URLs and SOAP services, regular wiki pages, uploaded files, files on the local server, databases, LDAP directories and local programs output.

The extension defines the following Функции парсера :

  • Data retrieval and handling functions, which set local variables and then display or store them:
  • In the Legacy mode the extension also defines data retrieval functions, which set local variables available with wikipage scope that can later be displayed using the above functions:
    • #get_external_data - retrieves data from various sources, thus replacing any of the below parser functions, and assigns it to variables that can be accessed on the page.
    • #get_web_data - retrieves CSV, GFF, JSON, YAML, XML, HTML, ini, or free-form data from a URL and assigns it to variables that can be accessed on the page.
    • #get_soap_data - retrieves data from a URL via the SOAP protocol.
    • #get_file_data - retrieves data from a file on the local server, in the same formats as #get_web_data.
    • #get_db_data - retrieves data from a database.
    • #get_ldap_data - retrieves data from an LDAP server.
    • #get_program_data - retrieves data returned by a program run server-side.
    • #get_inline_data - parses data passed to it, in the same formats as #get_web_data.
    • and also #clear_external_data that erases the current set of retrieved data or only some variables.

It also defines a Lua function mw.ext.externalData.getExternalData that retrieves data and returns it as Lua table.

In the Legacy mode, the following additional Lua functions are also defined (there is one-to-one correspondence between parser functions retrieving data and Lua functions evident from their names):

  • mw.ext.externalData.getWebData
  • mw.ext.externalData.getFileData
  • mw.ext.externalData.getDbData
  • mw.ext.externalData.getSoapData
  • mw.ext.externalData.getLdapData
  • mw.ext.externalData.getProgramData
  • mw.ext.externalData.getInlineData

In tag emulation mode, the wiki site administrator can define additional parser tags.

This version of the External Data extension requires MediaWiki 1.33+.
