Extension:External Data

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, regular wiki pages, uploaded files, files on the local server, databases and LDAP directories.

The extension defines the following :
 * #get_web_data - retrieves CSV, GFF, JSON, XML, HTML 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.
 * #external_value - displays the value of any such variable.
 * #for_external_table - cycles through all the values retrieved for a set of variables, displaying the same "container" text for each one.
 * #store_external_table - cycles through a table of values, storing them as semantic data via the Semantic MediaWiki extension, by mimicking a call to SMW's #subobject function for each row.
 * #display_external_table - cycles through all the values retrieved for a set of variables, displaying each "row" using a template.
 * #clear_external_data - erases the current set of retrieved data.

It defines one tag:
 * pair that shows raw external data without any wiki postprocessing.
