The Synapse project will create a robust, lightweight implementation of a highly scalable and distributed service mediation framework based on Web services specifications.

Synapse is a mediation framework for Web Services. Synapse allows messages flowing through, into, or out of an organization to be mediated, including aspects such as:

• Logging, service lookup, performance mediation

• Versioning, failover, monitoring

• Fault management, tracing

The user guide is available at http://wiki.apache.org/ws/Synapse/UserGuide

Synapse, incidentally, is pronounced "sine-apse", and not "sin-apse".

Synapse is an effort undergoing incubation at the Apache Software Foundation (ASF), sponsored by the Web Services PMC. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

We have released a first Milestone M1. The release will supports:

• Simple mediation based on regex and xpath rules

• Onbound routing of messages

• Deploy simple Java mediators to perform logging, routing, message transform etc

• XSLT transformation of messages

• HTTP Proxy support

• Stages and in/out handling of messages
