Open Data on the Open Platform
The document discusses the evolution of open data and open platforms, emphasizing the importance of open source movements and the democratization of technology and knowledge sharing among engineers. It highlights the challenges in creating interactive mapping applications with HTML5 due to the lack of standard geospatial features, as well as the potential of OpenStreetMap as an alternative to proprietary services like Google Maps. Workshops on geo and web technologies have been conducted to promote discussions and developments in this field, with a focus on creating a community around open data interoperability.

- 2. Open Source Movementsince late 90s • Everyone can read the source code of software • Everyone can participate to the development • Open the know-how of enterprise, large-scale software to engineers in every domain • Broke the barrier between amateur and enterprise technology • Create a chance of technological communication among engineers in different domains
- 3. Open Data Movement • Chance to democratize the knowledge of government, large company, specialists to citizen • Exchange the way of finding knowledge among TED talk by Tim Berners-Lee in 2010 http://www.ted.com/talks/tim_berners_lee_ the_year_open_data_went_worldwide.html
- 4. Open Platform Movementis Coming! • Platform: a common mechanism on which an application runs • OS，Middleware, Web service, Distribution mechanism of apps or content… • Organization who control the platform would have great benefit • Microsoft, Google, Apple, Facebook …. • Web technology (HTML5) is going to be the next platform • Vendor independent organization (W3C) • Open discussion of specification
- 5. Proprietary Platform • Softwarefor the one platform does not run on another platform
- 6. HTML5 as anOpen Application Platform • Web Browser is becoming to be an Application Platform • Create Application with HTML, CSS and JavaScropt • API Support for development • Basement • File API, Drag and Drop, Offline support • Graphics and animation • css3, canvas, SVG, WebGL. etc • Device, Hardware • Location, Accelerometer, etc
- 7. Little Support ofMap/Geo-Features in HTML5 • No Standard Map Feature • No standard API of rendering vector map • No standard API of drag and drop map • No standard API of expansion • Difficult to create interactive mapping apps. • Little Standard Geo-App Features Support • Geo Location API • Basic support to access to the GPS • No standard API to measure the distance • No standard API of geocoding / reverse geocoding • No standard API of geo event • Enter the area, stay more than 5 min etc..
- 8. Why Google ? • Why you use google maps ? • Because its content is wide coverage, rich info, accurate, beautiful… • OSM can be the alternative ! • Why you develop Geo/Map app with google maps API ? • Because it provides many useful features • Simple API to embed a Map • Measurement of the distance • Geocoding …. • There is no alternative ! • Need Open Geo / Mapping Platform!
- 9. Geo + WebWorkshop since 2010 • 1st: June, 2010 • 3 talks + 1 panel discussion (5 panelist) • 40 participants • 2nd: March 11, 2011 “Mapping technology in the HTML5 Era” • 3 talks + 1 panel discussion (5 panelists) • →Could not hold due to the Great East Japan Earthquake • 3rd: May, 2012 “Open Data on the Open Platform” • 5 talks • 60 more participants + 40 more online participants
