Table of Contents

The dumpRDF.php is a maintenance script allowing to export RDF triples.

Important Notes

  • This maintenance script depreciated the former "SMW_dumpRDF.php" script starting with Semantic MediaWiki 2.0 while options and usage at that time remain the same.
NoteNote:  It is strongly encouraged to make the transition to this new script to take advantage of the new features added since and because the old one will will be removed with the release of Semantic MediaWiki 3.0 in early 2017.
  • If SMW is not installed in its standard path then the "MW_INSTALL_PATH" environment variable must be set. See README in the maintenance directory.

Usage

php dumpRDF.php [--file|--categories|--classes|--concepts|--types|--individuals|--page|--properties|--d|--e]

NoteNote:  This only shows the script specific parameters.

Parameters

Generic parameters

--help (-h)
Display this help message
--quiet (-q)
Whether to supress non-error output
--conf:
Location of "LocalSettings.php", if not default
--wiki
For specifying the wiki ID
--globals
Output globals at the end of processing for debugging
--memory-limit
Set a specific memory limit for the script, "max" for no limit or "default" to avoid changing it
--server:
The protocol and server name to use in URLs, e.g. https://www.semantic-mediawiki.org. This is sometimes necessary because server name detection may fail in command line scripts.

Script dependant parameters

--dbuser
The DB user to use for this script
--dbpass
The password to use for this script

Script specific parameters

--file (-o) <filename>

--classes
Export only concepts and categories.
--properties
Export only properties.
--types
Export only data types.
--individuals
Export only pages that are no categories, properties, or types.
--page <pagelist>
Export only pages included in the <pagelist> with | being used as a separator. Options -e, -file, -d are ignored if --page is given. Available since Semantic MediaWiki 2.1.0.1
-d <delay>
Wait for this many milliseconds after processing an article. Useful for limiting server load.
-e <each>
Retire after the given number of exported entities.

Examples

The following command exports all pages into the given file delay of 50 ms between every exported item.
php dumpRDF.php --file MyWiki.rdf -d 50
