Community Data Science Workshops (Spring 2015)/Day 2 Projects/Socrata

Building a Dataset using the Socrata API and data.seattle.gov
In this project, we will explore a few ways to gather data from data.seattle.gov using the Socrata 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 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 section

Download and test the Socrata project
