Lists configuration parameters that site administrators may modify according to the particular needs of their wiki.
Table of Contents

Semantic MediaWiki offers a number of configuration parameters that site administrators may modify according to the particular needs of their wiki. This page explains all configuration parameters for Semantic MediaWiki. All available configuration parameters can also be found in the file "DefaultSettings.php" (as of Semantic MediaWiki 3.0.0Released on 11 October 2018 and compatible with MW 1.27.0 - 1.31.x.).

To change the setting of any configuration parameter, copy the respective assignment into your "LocalSettings.php" file, after including Semantic MediaWiki as described in installation. Do not change the "DefaultSettings.php" file directly, as your changes would be overwritten in software upgrades. See also the help page on function enableSemantics.

參見this page for a unordered list of configuration parameters.

Settings for inline queries

The following settings affect inline queries and querying special pages, in particular Special:Ask. Essentially they should mirror the kind of queries that should immediately be answered by the wiki, using whatever computations are needed.

Parameter	Description	Default	Version
$smwgQFilterDuplicates	Sets whether duplicate query conditions should be removed from computing query results	false	2.5.0+

Settings for Special:Ask

The following settings affect querying special pages, in particular Special:Ask. The settings for inline queries mentioned above also affect queries on special pages.

Parameter	Description	Default	Version

Settings for concept queries

Further settings for queries. The following settings affect queries that are part of concept pages. These are usually chosen to be less restricted than inline queries, since there are two other means for controlling their use:

1. Concept queries that would not be allowed as normal queries will not be executed directly, but can use pre-computed results instead. This is the default. See Concept caching for details on how to exploit this.
2. The whole Concept: namespace can be restricted (using some suitable MediaWiki extension) to an experienced user group that may create more complex queries resonably. Other users can employ thus defined concepts in their queries.

Parameter	Description
$smwgQConceptCaching	Which concepts should be displayed only if available from cache? Possible values are: CONCEPT_CACHE_ALL show concept elements anywhere only if they are cached, CONCEPT_CACHE_HARD show without cache if concept is not harder than permitted inline queries, or CONCEPT_CACHE_NONE show all concepts even without any cache. In any case, caches will always be used if available (but see $smwgQConceptCacheLifetime). Default: CONCEPT_CACHE_HARD
$smwgQConceptMaxSize	Same as $smwgQMaxSize but for concepts. Default: 20
$smwgQConceptMaxDepth	Same as $smwgQMaxDepth but for concepts. Default: 8
$smwgQConceptFeatures	Same as $smwgQFeatures but for concepts. Note that using concepts in concepts is currently not supported – do not enable it! Default: SMW_PROPERTY_QUERY | SMW_CATEGORY_QUERY | SMW_NAMESPACE_QUERY | SMW_CONJUNCTION_QUERY | SMW_DISJUNCTION_QUERY
$smwgQConceptCacheLifetime	This setting defines the cache life time in minutes. If a concept cache exists but is older than this, SMW tries to recompute it, and will only use the cache if this is not allowed due to settings above. Default: 24 * 60 (= 1 day)

Settings for full-text search

The following settings affect the full-text search.

Parameter	Description	Default	Version

Settings for query formatting/display

Parameter	Description
$smwgQDefaultLinking	Which result columns in an inline query should be linked if not specified otherwise. Possible values are 'none', 'subject' (links only in first column), 'all'. Default: 50
$smwgResultFormats	This setting contains an array of all query result formats that the wiki supports. It is normally extended automatically by extensions that supply additional formats. However, it is also possible to set this array manually, e.g. to disable some formats. To disable a format, do unset($smwgResultFormats['template']); Disabled formats will be treated like if the format parameter had been omitted. The formats 'table' and 'list' are defaults that cannot be disabled. The format 'broadtable' should not be disabled either in order not to break Special:Ask. Default: array( 'table' => 'SMWTableResultPrinter', 'list' => 'SMWListResultPrinter', 'ol' => 'SMWListResultPrinter', 'ul' => 'SMWListResultPrinter', 'broadtable' => 'SMWTableResultPrinter', 'category' => 'SMWCategoryResultPrinter', 'embedded' => 'SMWEmbeddedResultPrinter', 'template' => 'SMWListResultPrinter', 'count' => 'SMWListResultPrinter', 'debug' => 'SMWListResultPrinter', 'rss' => 'SMWRSSResultPrinter', 'csv' => 'SMWCsvResultPrinter', 'dsv' => 'SMWDSVResultPrinter', 'json' => 'SMWJSONResultPrinter', 'rdf' => 'SMWRDFResultPrinter' );
