You can get this from /data.json. I've been spending a bit more time with Socrata of late due to a research project I'm working on, and I've found some minor issues with the APIs, but have otherwise been happy with how the data is exposed. Also, while being grouchy about not being able to get a schema, I found this tool, which is now on my todo list to try: https://github.com/socrata/datasync

Socrata has been doing a nice little business here in Seattle! I keep half expecting Tableau to buy them out and then Microsoft to buy out Tableau. This PhD student has been keeping an eye on both as potential non-academic career routes.
