Welcome to the Enterprise Addressing System (EAS) Open Source Repository
The Enterprise Addressing System (EAS) is a Web application that allows employees of government agencies to create, edit, query, and retire (generally, maintain) numbered thoroughfare addresses. This site documents the EAS open source repository. If you are looking for the City and County of San Francisco's implementation of the EAS, then you can find that here.
An introductory video, San Francisco's Enterprise Addressing System: An Introduction, is available online. More in-depth videos are available in the Enterprise Addressing System (EAS) Help.

Technical Overview / Requirements
This page summarizes what technologies we use. The system is in production for the City of San Francisco as of mid-February 2012 (note that that instance is accessible only from within the internal City of SF network, but see "Demo" below). The README is a good place to start for more details, and this case study from Farallon Geographics gives a high-level overview of what EAS offers.
Our 2010 OSCON presentation is available in slide share and in powerpoint.
To try out EAS, you can set up your own demo instance Amazon Web Services, using a shared AMI provided by Farallon Geographics; see the AWS demo instructions for more. Anyone else who has a demo setup to offer, please let us know -- the more the merrier.
