Data “Ecosystem”
Open data
Open set of services & applications (APIs)
Us (creators, consumers)
*API - set of routines for accessing an application or service

Open Content
Web Charts, Graphs, Data Visualizations Applications

How “Free” is Data Troy Anderson’s from DataPlace – Google Tech Talk http://www.youtube.com/watch?v=Q_7MSaNXp-o (13:23)

Advantages of “Social” Data
Idealistic view
Cautiously optimistic
Skeptical

“Idealistic” Slide from: Bricolage: Data at Play Joe Hellerstein, UC Berkeley

Now - Future Slide from: Bricolage: Data at Play Joe Hellerstein, UC Berkeley

Idealistic
“ Soon, on Timepedia.org, you will be able to come join us in building the machine, or visualize, learn, and analyze our shared history, we hope for the betterment of the human condition. Sincerely, Timepedia's Staff”
http://timepedia.blogspot.com/2007/11/chronoscope-released.html

Skeptical/Pessimistic
Data Authority - garbage in, garbage out
Deliberate misinformation, spam, errors
Provenance
Privacy
“ Identifying “banned books” readers or by mining Amazon Wishlists and combining information with Yahoo People …

What Happens When
You combine the people and data and Web 2.0 tools?
Less “going with what my gut says”
“ Workable ” data
Reproducible results
Borrow from others
Level the playing field
(corporations & communities)
Disseminate expertise
