Slide 58: Day of the long tail

Slide 59: “Simple, intuitive and timely access to useful geographic data & information is my right and not a privilege” The new customer

Slide 60: It’s easy to dismiss Web2.0 at first glance

Slide 61: You cannot be serious!

Slide 62: http://kiva.org

Slide 63: “Simple, intuitive and timely access to useful geographic data & information is my right and not a privilege” The new customer

Slide 64: What do they get from us? WFS, WMS, WCS, WPS, WxS, blah, blah, blah …

Slide 65: What do they get from us? forgot it! WFS, WMS, WCS, WPS, WxS, blah, blah, blah …

Slide 66: they create their own community standards for sharing data … but are they any good?

Slide 67: Are they any good? “These powerful forces are creating ‘tensions’ that impact how we shape and create standards for the global community …

Slide 68: Are they any good? “Many of these tensions and associated market forces are the same ones that are driving the evolution of the Web (Web 2.0 and Where 2.0) and the integrated GeoWeb …

Slide 69: Are they any good? KML and GeoRSS are two new formats that are making great headway on the Web …

Slide 70: Are they any good? … strong collaboration between the "traditional" standards community and the Where 2.0 community can provide the greatest benefit for everyone” Can you guess who said this?

Slide 71: Are they any good? … strong collaboration between the "traditional" standards community and the Where 2.0 community can provide the greatest benefit for everyone” Carl Reed CTO, Open Geospatial Consortium, Inc.
