MediaWiki Key features
MediaWiki Key features • Everyone can edit
MediaWiki Key features • Everyone can edit • Rich content • Organization • Customization • Internationalization • Scalable
Semantic Web So what are semantics? • Make data understandable for computers • Make queries possible • Cross site
Semantic MediaWiki • Automatically-generated lists • Visual display of information • Improved data structure • Searching information • Inter-language consistency • External reuse “Collaborative Database”
Semantic MediaWiki Semantic search Ask function {{#ask: }} {{ #ask: }}
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 }}
Semantic MediaWiki Semantic Properties MediaWiki link: [[Germany]] [[capital of::Germany]] MediaWiki text: 3,396,990 [[population::3,396,990]]
Semantic MediaWiki Result Formats {{ #ask: [[Category:City]] [[located in::Germany]] | ?population | format=ul }}
Semantic MediaWiki Result Formats {{ #ask: [[Category:City]] [[located in::Germany]] | ?population | ?area#km² = Size in km² | ?coordinates | format=map }}
Maps • MediaWiki extension • Hooks into • Validator • Functionality • Visual display of coordinate data • Geocoding
Maps • Key features • Multiple mapping services • Multiple geocoding services • Modular build • Error feedback • Very configurable • API for mapping functionality

Maps Mapping services
Maps So how do I customize a map?
Maps Map properties {{ #display_map: New York City | property = value | property 2 = value 2 }}
Maps Map properties
Maps Map properties: default property {{#display_map: New York City}} {{#display_map: address = New York City}} {{#display_map: coordinates = New York City}} {{#display_map: coordinates = 55.7557860, 37.6176330}}
Maps Map properties: service {{ #display_point: Moscow, Russia}} {{ #display_point: Moscow, Russia | service=googlemaps }}
Maps Map properties: geoservice {{ #display_point: Moscow, Russia | geoservice=geonames }}
Maps Map properties: width and height {{ #display_point: Moscow, Russia | width = 800 | height = 420 }}
Maps Map properties: zoom and centre {{ #display_point: Moscow, Russia | zoom = 10 | centre = Brussels }}
Maps Map properties: zoom and centre {{ #display_point: Moscow, Russia; Brussels; Rome; Berlin }}
Maps Map properties: zoom and centre {{ #display_point: Moscow, Russia; Brussels; Rome; Berlin | zoom = 2 }}
Maps Map properties: title, label and icon {{ #display_point: Moscow; Brussels; Rome | icon = Green marker.png | title = A capital in Europe }}
Maps Map properties {{ #display_point: zoom=10 |width=1200 |height=1000 | 55.7557860, 37.6176330 | service = google | type = physical | types = terrain, hybrid, earth | controls = large, overview-map, scale, type }}
