Semantic MediaWiki Defining semantic data Article: Germany Content: The captial of Germany is [[Berlin]] with a population of 3,396,990 people.

Semantic MediaWiki Defining semantic data Article: Germany Content: The captial of Germany is [[Berlin]] with a population of 3,396,990 people. ● [[Berlin]] => [[Has capital::Berlin]] ● 3,396,990 => [[Has population::3,396,990]]

Semantic MediaWiki Defining semantic properties Property Has population ● /Property:Has population ● Type specified with “has type” property: ● [[has type::Number]]

Semantic MediaWiki Semantic search ● Ask function {{#ask: }} ● Special:Ask ● Multiple GUIs provided by extensions

Semantic MediaWiki Semantic search Criteria: Which pages to select [[Category:Actor]] [[born in::Boston]] [[height::180cm]] [[Category:Actor]] [[height::>6 ft]] [[height::<7 ft]] [[born in::Boston]] OR [[born in::New York]] [[Category:Cities]] [[located in.member of::European Union]]

Semantic MediaWiki Semantic search Criteria: Which information should be displayed? ?population ?area#km²

Semantic MediaWiki Semantic search Example: {{ #ask: [[Category:City]] [[located in::Germany]] | ?population | ?area#km² = Size in km² }}
