2. Presentation outline • Introduction to MediaWiki • Introduction to Semantic MediaWiki • Questions • Maps • Semantic Maps • Questions

3. MediaWiki

4. MediaWiki Key features

5. MediaWiki

6. MediaWiki

7. MediaWiki Key features • Everyone can edit

8. MediaWiki

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

10. MediaWiki

11. Semantic Web So what are semantics? • Make data understandbale 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 }}

22. Maps • MediaWiki extension • API for mapping functionality • Parser functions • display_point • display_points • Geocoding • geocode • display_address • display_addresses • Multi mapping/geocoding service support

23. Maps Mapping services

24. Maps Parser functions: display_point {{ #display_point: coordinates = 55.7557860, 37.6176330 | service = googlemaps | type = hybrid }}

25. Maps Parser functions: Parameters

26. Maps Parser functions: Parameters {{ #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 }}

28. Maps Parser functions: Parameters {{ #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?

29. Maps Parser functions: Spesific parameters Google Maps Yahoo! Maps OpenLayers

30. What about multiple locations? (I can has muhltiple locathiunz?)

31. Maps Parser functions: display_points {{#display_points: 55.7557860, 37.6176330; 42.424242, 42.424242}}

32. Maps Parser functions: Location info {{ #display_points: coordinates = 42.424242, 42.424242~The answer!; 55.7557860, 37.6176330~Moscow~The capital of Russia~green.png }}

34. Maps Geocoding {{#geocode:Moscow}}  55.7522222, 37.6155556 {{ #display_point: {{#geocode:Moscow}} }} = {{#display_address: Moscow}} {{ #display_points: {{#geocode:Moscow}}, {{#geocode:New York}} }} = {{#display_addresses: Moscow, New York}}

35. Maps Geocoding: Services {{#display_address: Moscow}}  Uses the default {{#display_address: Moscow |geoservice=yahoo }}  Uses the Yahoo! Service {{#geocode:Moscow, Russia|geonames}}  Uses the GeoNames Service

36. Maps Geocoding: Parameters

37. Semantic Maps • MediaWiki extension • Hooks into • Maps • Semantic MediaWiki • Semantic Forms • Functionality • Aggregation of coordinates (Result formats) • Insertion of coordinates (Form inputs)

38. Semantic Maps Mapping service • Identical to the ones of Maps • Google Maps • Yahoo! Maps • OpenLayers

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

40. Semantic Maps Result formats {{ #ask: [[Category:City]] [[located in::Germany]] | ?population | ?area#km² = Size in km² | ?coordinates | format=openlayers }}

41. Semantic Maps Result formats: Parameters {{ #ask: [[Category:City]] [[located in::Germany]] | ?population | ?area#km² = Size in km² | ?coordinates | format=openlayers | width = 500 | height = 300 | zoom = 10 }}

42. Semantic Maps Result formats: Parameters

43. Semantic Maps Result formats: Example {{ #ask: [[Category:City]] [[located in::Germany]] | ?population| ?area#km² = Size in km² | ?coordinates | format=openlayers | width=800 | height=500 | zoom=4 | center={{#geocode:Moscow, Russia}} | layers=google-physical,yahoo,google,bing,openlayers,nasa }}

45. Semantic Maps Form Inputs • Semantic Forms hook • Allows • Coordinate insertion • Easy editing of coordinate data With a visual interface (= No wiki code!)

46. Semantic Maps Form Inputs: Syntaxis {{{ field |The coordinates |input type=yahoomaps }}}

47. Semantic Maps Form Inputs: Parameters {{{ field |The coordinates |input type=yahoomaps |width=800 |height=500 |zoom=8 |autozoom=off }}}

48. Semantic Maps Form Inputs : Parameters

49. Semantic Maps Form Inputs: Example {{{ field |The coordinates |input type=yahoomap |width=800 |height=500 |autozoom=off }}}
