  7. MediaWiki

  8. MediaWiki Key features • Everyone can edit

  9. MediaWiki

  10. MediaWiki Key features • Everyone can edit • Rich content • Organization • Customization • Internationalization • Scalable

  11. Semantic Web So what are semantics? • Make data understandable for computers • Make queries possible • Cross site

  12. Semantic MediaWiki

  13. Semantic MediaWiki • Automatically-generated lists • Visual display of information • Improved data structure • Searching information • Inter-language consistency • External reuse  “Collaborative Database”

  14. Semantic MediaWiki Semantic search Ask function {{#ask: }} {{ #ask: }}

  15. 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]]

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

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

  18. Semantic MediaWiki Semantic Properties MediaWiki link: [[Germany]]  [[capital of::Germany]] MediaWiki text: 3,396,990  [[population::3,396,990]]

  19. Semantic MediaWiki Result Formats {{ #ask: [[Category:City]] [[located in::Germany]] | ?population | format=ul }}

  20. Semantic MediaWiki Result Formats {{ #ask: [[Category:City]] [[located in::Germany]] | ?population | ?area#km² = Size in km² | ?coordinates | format=map }}

  21. Maps • MediaWiki extension • Hooks into • Validator • Functionality • Visual display of coordinate data • Geocoding

  22. Maps • Key features • Multiple mapping services • Multiple geocoding services • Modular build • Error feedback • Very configurable • API for mapping functionality

  23. Maps Coordinates • Floats: 55.7557860, 37.6176330 • DMS: 55°45′06″N 37°37′04″E • DD: 55.7557860°, 37.6176330° • DM: 55°45.34716', 37°37.05798'

  24. Maps Geocoding {{ #geocode:Moscow, Russia}}  55.7557860, 37.6176330

  25. Maps Geocoding services • Google • Yahoo • GeoNames {{#geocode:Moscow, Russia|geonames}}

  26. Maps Smart geocoding • Display_map • Display_point(s) • Centre parameter ! Display_address(es) has been deprecated since 0.4

  27. Maps Displaying a map {{#display_map: Moscow}} Or {{#display_map: 55°45′06″N 37°37′04″E}} Or ...

  28. Maps Displaying points {{#display_point: Moscow}} Or {{#display_point: 55.7557860, 37.6176330}} Or ...

  29. Maps Displaying points {{ #display_points: 55°45′06″N 37°37′04″E; New York; 40.446195, -79.948862 }}

  30. Maps Displaying points: point specific data Address~Title~Label~Icon

  31. Maps Displaying points: point specific data {{ #display_points: Brussels; New York~New York city; Moscow, Russia~Moscow~A city in Russia; London~[[London]]~Capital of England~Green marker.png; Mali~Mali~~Blue marker.png }}

  32. Maps Mapping services

  33. Maps So how do I customize a map?

  34. Maps Map properties {{ #display_map: New York City | property = value | property 2 = value 2 }}

  35. Maps Map properties

  36. 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}}

  37. Maps Map properties: service {{ #display_point: Moscow, Russia}} {{ #display_point: Moscow, Russia | service=googlemaps }}

  38. Maps Map properties: geoservice {{ #display_point: Moscow, Russia | geoservice=geonames }}

  39. Maps Map properties: width and height {{ #display_point: Moscow, Russia | width = 800 | height = 420 }}

  40. Maps Map properties: zoom and centre {{ #display_point: Moscow, Russia | zoom = 10 | centre = Brussels }}

  41. Maps Map properties: zoom and centre {{ #display_point: Moscow, Russia; Brussels; Rome; Berlin }}

  42. Maps Map properties: zoom and centre {{ #display_point: Moscow, Russia; Brussels; Rome; Berlin | zoom = 2 }}

  43. Maps Map properties: title, label and icon {{ #display_point: Moscow; Brussels; Rome | icon = Green marker.png | title = A capital in Europe }}

  44. 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 }}

  45. 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 }} Not in the list?
