Семантична МедіаВікі пропонує ряд налаштувань, що адміністратори сайтів можуть змінювати згідно певних потреб. Ця сторінка показує всі варіантти налаштувань версії 1.7.0 і вище. Всі доступні варіанти налаштувань можуть бути знайдені у файлі SMW_Settings.php, що відповідає певній версії. Для зміни налаштувань, слід скопіювати відповідні значення у LocalSettings.php, як показано у іструкції з встановлення. Не змінюйте SMW_Settings.php прямо, оскільки ваші зміни можуть бути затерті оновленнями програмного забезпечення.

Налаштування при встановленні[edit]

The following settings relate to the basic installation of SMW.

Parameter Description
$smwgNamespaceIndex If you already have custom namespaces on your site, insert
  $smwgNamespaceIndex = ???;

into your LocalSettings.php before including SemanticMediaWiki.php (formerly SMW_Settings.php). The number ??? must be the smallest even namespace number that is not in use yet. However, it must not be smaller than 100.

Default: 100

$smwgEnableUpdateJobs SMW defers some tasks until after a page was edited by using the MediaWiki job queueing system (see the manual on job queues). For example, when the type of a property is changed, all affected pages will be scheduled for (later) update. If a wiki generates too many jobs in this way, the following setting can be used to disable jobs. Note that this will cause some parts of the semantic data to get out of date, so that manual modifications or the use of SMW_refreshData.php might be needed.

Default: true

$smwgLinksInValues Should SMW accept inputs like [[property::Some [[link]] in value]]? If enabled, this may lead to PHP crashes (!) when very long texts are used as values. This is due to limitations in the library PCRE that PHP uses for pattern matching. The provoked PHP crashes will prevent requests from being completed – usually clients will receive server errors ("invalid response") or be offered to download "index.php". It might be okay to enable this if such problems are not observed in your wiki.

Default: false

$smwgUseCategoryHierarchy Should SMW consider MediaWiki's subcategory hierarchy in querying? If set to true, subcategories will always be interpreted like subclasses. For example, if A is a subcategory of B then a query for all elements of B will also yield all elements of A. If this setting is disabled, then subclass relationships can still be given explicitly by using the property Property:Subcategory of on some category page. Only if the setting is false will such annotations be shown in the Factbox (if enabled).

Default: true

$smwgCategoriesAsInstances Should category pages that use some [[Category:Foo]] statement be treated as elements of the category Foo? If disabled, then it is not possible to make category pages elements of other categories. See also the above setting $smwgUseCategoryHierarchy.

Default: true

$smwgNamespacesWithSemanticLinks Overwriting the following array, you can define for which namespaces the semantic links and annotations are to be evaluated. On other pages, annotations can be given but are silently ignored. This is useful since, e.g., talk pages usually do not have attributes and the like. In fact, is is not obvious what a meaningful attribute of a talk page could be. Pages without annotations will also be ignored during full OWL/RDF export, unless they are referred to from another article.


$smwgNamespacesWithSemanticLinks = array(
	              NS_MAIN => true,
	              NS_TALK => false,
	              NS_USER => true,
	         NS_USER_TALK => false,
	           NS_PROJECT => true,
	      NS_PROJECT_TALK => false,
	             NS_IMAGE => true,
	        NS_IMAGE_TALK => false,
	         NS_MEDIAWIKI => false,
	    NS_MEDIAWIKI_TALK => false,
	          NS_TEMPLATE => false,
	     NS_TEMPLATE_TALK => false,
	              NS_HELP => true,
	         NS_HELP_TALK => false,
	          NS_CATEGORY => true,
	     NS_CATEGORY_TALK => false,
	     SMW_NS_PROPERTY  => true,
	          SMW_NS_TYPE => true,
	     SMW_NS_TYPE_TALK => false,
	       SMW_NS_CONCEPT => true,
	  SMW_NS_CONCEPT_TALK => false,
$smwgDefaultNumRecurringEvents This is a setting for recurring events, created with the #set_recurring_event parser function. This setting defines the default number of instances defined by this parser function, if no end date is set.

Default: 100

$smwgMaxNumRecurringEvents This is a setting for recurring events, created with the #set_recurring_event parser function. This setting defines the maximum number that can be defined by this parser function, regardless of an end date.

Default: 500

$smwgPageSpecialProperties List of enabled page-related special properties. The setting was introduced in Semantic MediaWiki 1.7.0. Other possible settings are:
  • array( '_CDAT' ) (corresponds to special property Creation date)
  • array( '_NEWP' ) (corresponds to special property Is a new page)
  • array( '_LEDT' ) (corresponds to special property Last editor is)
  • array( '_MDAT', '_CDAT', /* ... */ ) - multiple used
  • array( ) - none used

See the help page on $smwgPageSpecialProperties for detailed information to set this parameter.

Default: array( '_MDAT' ) (corresponds to special property Modification date)

Parameter Description
$smwgShowFactbox This setting allows you to select in which cases you want to have a factbox appear below an article. Note that the Magic Words __SHOWFACTBOX__ and __NOFACTBOX__ can be used to control Factbox display for individual pages. Other options for this setting include:
  • $smwgShowFactbox = SMW_FACTBOX_NONEMPTY; show only those factboxes that have some content
  • $smwgShowFactbox = SMW_FACTBOX_SPECIAL; show only if special properties were set
  • $smwgShowFactbox = SMW_FACTBOX_HIDDEN; hide always
  • $smwgShowFactbox = SMW_FACTBOX_SHOWN; show always, buggy and not recommended


$smwgShowFactboxEdit Same as $smwgShowFactbox but for edit mode and same possible values.


$smwgToolboxBrowseLink Should the toolbox of each content page show a link to browse the properties of that page using Special:Browse? This is a useful way to access properties and it is somewhat more subtle than showing a Factbox on every page.

Default: true

$smwgInlineErrors Should warnings be displayed in wikitexts right after the problematic input? This affects only semantic annotations, not warnings that are displayed by inline queries or other features.

Default: true

$smwgSearchByPropertyFuzzy Should the search by property special page display nearby results when there are only few results with the exact value? Switch this off if this page has performance problems.

Default: true

$smwgTypePagingLimit Number of results shown in the listings on pages in the namespace Type.

Default: 200

$smwgConceptPagingLimit Number of results shown in the listings on pages in the namespace Concept.

Default: 200

$smwgPropertyPagingLimit Number of results shown in the listings on pages in the namespace Property. Uses a smaller value since these lists need more space.

Default: 25

$smwgMaxPropertyValues Number of values that are shown for each page in the listing on property pages. If increased to higher values, it might be useful to reduce $smwgPropertyPagingLimit to avoid performance impacts when showing property pages.

Default: 3

$smwgMaxNonExpNumber The maximal number that SMW will normally display without using scientific exp notation. The default is rather large since some users have problems understanding exponents. Scientific applications may prefer a smaller value for concise display.

Default: 1000000000000000

Налаштування запитів[edit]

Settings for inline queries and for semantic queries in general. This can especially be used to prevent overly high server-load by complex queries. The following settings affect all queries, wherever they occur. ... further results

Parameter Description
$smwgQSubpropertyDepth Restrict level of sub-property inclusion (steps within property hierarchy). Use 0 to disable hierarchy-inferencing in queries.

Default: 10

$smwgQSortingSupport Should sorting of query results be possible?

Default: true

$smwgQRandSortingSupport Enables or disables the random sorting of query results.

Default: true

$smwgQDefaultNamespaces Which namespaces should be searched by default? A value of NULL switches off default restrictions on searching, which is faster. An example value with namespaces would be array(NS_MAIN, NS_IMAGE).

Default: NULL

$smwgQComparators List of comparator characters supported by queries, separated by '|'. Possible entries for this list are
  • < (smaller than or equal)
  • > (greater than or equal)
  • << (smaller than)
  • >> (greater than)
  • ≤ (smaller than or equal - note that this is an extended ASCII character and may show up differently, e.g. as â¤)
  • ≥ (greater than or equal - note that this also is an extended ASCII character and may show up like â¥)
  •  ! (unequal to)
  • ~ (matching a pattern with '*' as wildcard, only for datatype String)
  •  !~ (not matching a pattern with '*' as wildcard, only for datatype String)

If unsupported comparators are used, they are treated as part of the queried value. The behaviour of the comparators < and > varies depending on the setting for $smwStrictComparators.

Default: '<|>|!~|!|~|≤|≥|<<|>>'

$smwStrictComparators Enables or disables strict treatment of comparator symbols.

Default: false

$smwgIgnoreQueryErrors Should queries be executed even if some errors were detected? A hint that points out errors is shown in any case.

Default: true

Налаштування вбудованих запитів та Special:Ask[edit]

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.

... further results

Налаштування запитів-понять[edit]

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).


$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!


$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)

Налаштування для запитів formatting/display[edit]

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: 'all'

$smwgQDefaultLimit Default number of rows returned in a query. Can be increased with limit=... in #ask.

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.


	'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'

OWL/RDF експорт[edit]

Parameter Description
$smwgAllowRecursiveExport Can normal users request recursive export, i.e. an OWL/RDF export that includes a full export of all mentioned pages, and of all pages they mention, and so on. Recommended only for very small wikis.

Default: false

$smwgExportBacklinks Should incoming properties be part of OWL/RDF export?

Default: true

$smwgNamespace The URI-namespace of exported URIs. Will be set automatically if nothing is given, using the base URL provided to enableSemantics(). But in order to make pretty URIs you will need to set this to something nice and adapt your Apache configuration appropriately. This is done, e.g., on, where URIs are of the form An example setting would be
$smwgNamespace = '';

Default: unset

Other settings[edit]

The following settings usually need no modification.

SPARQL та RDF налаштування[edit]

See also the help page on configuring SWM for use with SPARQL and RDF stores.

... further results

Parameter Description
$smwgSparqlDatabase Configure SPARQL database connection for Semantic MediaWiki. This is used when SPARQL-based features are enabled, e.g. when using 'SMWSparqlStore' as the $smwgDefaultStore. The default setting uses a generic SPARQL connector that is based on recent SPARQL documents. However there are settings available for use with specific connectors:
  • 'SMWSparqlDatabase4Store' for use with 4Store
  • 'SMWSparqlDatabaseVirtuoso' for use with Virtuoso

Default: 'SMWSparqlDatabase'

$smwgSparqlQueryEndpoint Configure SPARQL database connection for Semantic MediaWiki. This is used when SPARQL-based features are enabled. Endpoint (service URL) for queries (reading queries like SELECT). This endpoint is neccessary.

Default: 'http://localhost:8080/sparql/'

$smwgSparqlUpdateEndpoint Configure SPARQL database connection for Semantic MediaWiki. This is used when SPARQL-based features are enabled. Endpoint (service URL) for updates (SPARQL Update queries). Can be omitted if not supported.

Default: 'http://localhost:8080/update/'

$smwgSparqlDataEndpoint Configure SPARQL database connection for Semantic MediaWiki. This is used when SPARQL-based features are enabled. Endpoint (service URL) for data (SPARQL HTTP Protocol for Graph Management) Can be omitted if not supported.

Default: 'http://localhost:8080/data/'

$smwgSparqlDefaultGraph The default graph is similar to a database name in relational databases. It can be set to any URI (e.g. the main page URI of your wiki with "#graph" appended). Leaving the default graph URI empty only works if the store is configured to use some default graph or if it generally supports this. Different wikis should normally use different default graphs unless there is a good reason to share one graph.

Default: ''

Інші налаштування[edit]

Parameter Description
$smwgPDefaultType Default property type. Undefined properties (those without pages or whose pages have no "has type" statement) will be assumed to be of this type. This is an internal type id. See the file languages/SMW_LanguageXX.php to find what IDs to use for datatpyes in your language. The default corresponds to "Type:Page". The English ids are as follows:
  • '_wpg' → Page
  • '_str' → String
  • '_txt' → Text
  • '_cod' → Code
  • '_boo' → Boolean
  • '_num' → Number
  • '_geo' → Geographic coordinates
  • '_tem' → Temperature
  • '_dat' → Date
  • '_ema' → Email
  • '_uri' → URL
  • '_anu' → Annotation URI
  • '_tel' → Telephone number
  • '_rec' → Record
  • '_qty' → Quantity

Default: '_wpg' (corresponds to datatype Page)

$smwgTranslate Setting this to true allows to translate all the labels within Special:Browse given that they have interwiki links. This feature is currently disabled and cannot be activated with this setting.

Default: false

$smwgAdminRefreshStore If the following is set to true, the wiki data can be repaired using the interface on the page Special:SMWAdmin. Setting this option to false does not stop ongoing repair processes.

Default: true

$smwgHistoricTypeNamespace If the following is set to true, you can still access the old namespaces Type (104) and Type_talk (105) which have been replaced by Special:Types and are thus obsolete starting with SMW 1.6.0.

Default: false
