10. Example #1: Share your website
1. Create widget for your application (AddThis or Sharethis)
3. Customize the widget (type of sharing)
– Email
– Social bookmark
– Social media (FB, Twitter…)
5. Add script

11. Example #2: Socialize your map
1. Create a web mapping application
3. Add a share widget
5. Add state code
– Extents
– Custom location
• Send URL to
Twitter
Facebook…

12. Example #3: RSS or GEORSS-enable your sites
1. Add RSS or GEORSS broadcasting capabilities
3. Subscribe to your feed
GEOS
(Group on Earth Observations)
– RSS
– GeoRSS
– Geoss.esri.com
– Twitter.com/geoportal

13. Example #4: Sharing maps as gadgets and widgets
1. Create an ArcGIS API for JavaScript app
2. Wrap it in Google XML + preferences
• Share with others
• Self-Host or cloud
• Discovery….

14. Google Gadget API
• Pro’s
– No usage limits when hosted on Google
– Open access requests – no password required
– Many options for publication
– Lots of samples
• Con’s
– Challenging to build and test
• Resources
– API - http://code.google.com/apis/gadgets/
– http://www.google.com/webmasters/gadgets/

15. Example #5: Integrate with social media APIs
1. Get the location information from the API
3. Geolocate or geocode elements
5. Bring “value” to application and users
Think about
– Security
– Access limitations
– Customer

16. Adobe ActionScript Facebook API
• Pro’s
– Many official and unofficial client libraries
– No connection limits for web apps
– Free access requests and password requests
– Lots of functionality
• Con’s
– How-to docs limited beyond the very basics
• Resources
– Facebook API – http://developers.facebook.com
– Adobe AS3 Facebook Home - http://www.adobe.com/devnet/facebook/
– AS3 FB Library Docs -

17. Twitter APIs
• Twitter search and a status-based REST API
– XML, JSON, RSS or Atom
• 150 calls per hour (was 100!), can request more “Whitelisting”
• Open access requests vs password requests
• Resources
– API – http://apiwiki.twitter.com
– Twitter Development Talk (Google Group)
