OpenSRF
Open Scalable Request Framework (OpenSRF), pronounced “open surf” is a message routing network that offers scalability and failover support for individual services and entire servers with minimal development and deployment overhead. You can use OpenSRF to build loosely-coupled applications that can be deployed on a single server or on clusters of geographically distributed servers using the same code and minimal configuration changes.

Developing on OpenSRF
Dan Scott has written a two part article which is a detailed introduction to OpenSRF. “This article introduces OpenSRF, how to build OpenSRF services through code examples, explains the technical foundations on which OpenSRF is built, and evaluates OpenSRF’s value in the context of Evergreen” – “Easing gently into OpenSRF, Part 1” and “Easing gently into OpenSRF, Part 2“.
He also has an introductory workshop available along with some Perl/JavaScript examples – “Evergreen development“.

Source Code Repository
A Gitweb instance sits atop the Git repositories for Evergreen and OpenSRF. You can find both repositories at git.evergreen-ils.org and mirrored on github at https://github.com/evergreen-library-system.
Here is the running change log for the Evergreen code repository: watch us work.
There is also a gitstats page summarizing Evergreen code activity.
TODO: are the commits lists still active? have they been migrated off of GA Libs like the others?
Trac sends code commits to two public Evergreen mailing lists:
- For Evergreen commits, subscribe to open-ils-commits
- For OpenSRF commits, subscribe to opensrf-commits
