== Building a Dataset using the Socrata API and data.seattle.gov ==

In this project, we will explore a few ways to gather data from [https://data.seattle.gov data.seattle.gov] using the [[http://www.socrata.com Socrata open data] API. Once we've done that, we will extend this to code to create our own datasets of civic data that we might be able to use to ask and answer questions in the final session.

=== Goals ===

* Get set up to build datasets with the [http://dev.socrata.com/consumers/getting-started.html Socrata API]
* Have fun collecting different types of data from data.seattle.gov
* Practice reading and extending other people's code
* Create a few collections of different types of data from Socrata that you can do research with in the final workshop session

== Today's project: Analyzing traffic on the Burke-Gilman Trail ==

(Estimated time: 10 minutes)

=== Topics to cover ===

* explain Socrata open data platform, exists on other government websites
* navigate to [http://en.wikipedia.org/w/api.php api page] and show the documentation, point out examples
* introduce the [https://www.hurl.it API sandbox] as a tool for building queries

=== Example questions ===
* What Seattle neighborhood has the most art galleries? - [http://jtmorgan.net/cdsw/neighborhood_culture1.py neighborhood_culture1.py]
* What Seattle neighborhood has the most square feet devoted to arts & culture?  - [http://jtmorgan.net/cdsw/neighborhood_culture2.py neighborhood_culture2.py]
* Which trail gets more bike traffic per month--the [[w:Burke-Gilman_Trail|Burke Gilman]] or the [[w:Mountains_to_Sound_Greenway|Mountain to Sound Trail]]?  - [http://jtmorgan.net/cdsw/traffic_counter1.py traffic_counter1.py], [http://jtmorgan.net/cdsw/traffic_counter2.py traffic_counter2.py]
* Do people use the trails less when it's cold? [http://jtmorgan.net/cdsw/monthly_weather.py monthly_weather.py]
* Does the Burke-Gilman get more bike or pedestrian traffic? [http://jtmorgan.net/cdsw/bike_and_peds1.py bike_and_peds1.py]
* What is the primary commute direction on the Burke Gilman? [http://jtmorgan.net/cdsw/bike_and_peds1.py bike_and_peds2.py]

;Other example questions
* What day of the week does the Burke Gilman have the most total traffic? 
* What day has the most pedestrian traffic? 
* What ''time of day'' has the most southbound traffic, on average?
* How many shoplifting calls has SPD responded to this month so far?
