From an Information Week Article:
Fashioned similarly to other open-data sites but with its own innovations, Data.Oregon.gov lets people view data sets from government agencies; interact with that data by creating charts, graphs, calendars, and maps; and make suggestions for the release of data sets they find valuable, according to the Oregon Department of Administrative Services, which unveiled the site (PDF) this week.
Data sets released on the site include financial information about state expenditures, employment salaries, and employment information. The site also includes data about new businesses registered in the state and lists of people who are housed in Oregon prisons.
