# 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 class SMWSparqlDatabase works with many databases that support
# SPARQL and SPARQL Update. Three different endpoints (service URLs) are given
# for query (reading queries like SELECT), update (SPARQL Update queries), and
# data (SPARQL HTTP Protocol for Graph Management). The query endpoint is
# necessary, but the update and data endpoints can be omitted if not supported.
# This will lead to reduced functionality (e.g. the SMWSparqlStore will not
# work if Update is not available). The data endpoint is always optional, but
# in some SPARQL databases this method is more efficient than update.
#
# 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 configure to use some default 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.

# These are fixed properties, i.e. user defined properties having a
# dedicated table for them. Entries in this array have the following format:
#
# 		property_key => property_type.
#
# The 'property_key' is the title of the property (with underscores instead
# of _ and capital first letter).
# The 'property_type' denotes the type of the property and has to be one of the following:
#		SMWDataItem::TYPE_BLOB
#		SMWDataItem::TYPE_URI
#		SMWDataItem::TYPE_WIKIPAGE
#		SMWDataItem::TYPE_NUMBER
#		SMWDataItem::TYPE_TIME
#		SMWDataItem::TYPE_BOOLEAN
#		SMWDataItem::TYPE_CONTAINER
#		SMWDataItem::TYPE_GEO
#		SMWDataItem::TYPE_CONCEPT
#		SMWDataItem::TYPE_PROPERTY
#
# A run of setup using SMWAdmin is needed to create these tables. If an already used property is assigned a new table all old data for this property will
# become inaccessible for SMW. This can be repaired by either migrating it to the new table (repair data) or will eventually be updated on page edits.
#
# Example: If you have a property named 'Age' which is of type 'Number' then add in LocalSettings:
#
# 	$GLOBALS['smwgFixedProperties'] = array(
#		'Age' => SMWDataItem::TYPE_NUMBER
#  	);

# Features or restrictions for specific DataValue types
#
# - SMW_DV_NONE
#
# - SMW_DV_PROV_REDI (PropertyValue) If a property is redirected to a different
# target (Foo -> Bar) then follow it by default in order to allow query results
# to be displayed equivalent for both queries without having to adjust
# (or change) a query. This flag is mainly provided to restore backwards
# compatibility where behaviour is not expected to be altered, nevertheless it is
# recommended that the setting is enabled to improve user friendliness in terms
# of query execution.
#
# - SMW_DV_MLTV_LCODE (MonolingualTextValue) is to require a language code in order
# for a DV to be completed otherwise a MLTV can operate without a language code
#
# - SMW_DV_PVAP (Allows pattern) to allow regular expression pattern matching
# when `Allows pattern` property is assigned to user-defined property
#
# - SMW_DV_WPV_DTITLE (WikiPageValue) is to allow requesting a lookup for a display
# title and if present will be used as caption for the invoked subject
#
# - SMW_DV_PROV_DTITLE (PropertyValue) in combination with SMW_DV_WPV_DTITLE; If
# enabled it will attempt to resolve a property label by matching it against a
# possible assigned property "Display title of" value. For example, property
# "Foo" has "Display title of" "hasFoolishFoo" where "hasFoolishFoo" is being
# resolved as "Foo" when creating annotations. Currently, this uses an
# uncached lookup and therefore is disabled by default to avoid a possible
# performance impact (which has not been established or analyzed).
#
# - SMW_DV_PVUC (Uniqueness constraint) to specify that a property can only
# assign a value that is unique in its literal representation (the state of
# uniqueness for a value is established by the fact that it is assigned before
# any other value of the same representation to a property).
#
# - SMW_DV_TIMEV_CM (TimeValue) to indicate the CalendarModel if is not a
# CM_GREGORIAN

# @since 2.4
