Avis Router 1.2.2

Avis is an event router service compatible with the commercial Elvin implementation developed by Mantara Software.
Avis is an event router service compatible with the commercial Elvin implementation developed by Mantara Software. The project provides a general-purpose, scalable publish/subscribe message bus using content-based subscriptions.

Elvin is a flexible event router that allows arbitrary messages (a.k.a. notifications) to be exchanged via a publish/subscribe model. Elvin clients subscribe to messages using expressions that match messages by their content, an approach that differs from most other message bus systems that operate by selecting messages published on pre-defined channels. Elvin routers can also be federated to construct high-efficiency, wide-area event networks.

The name "Avis" derives from the French word avis, meaning advice or notification.

Applications:

Current uses for Elvin include providing the message bus for instant messaging and virtual presence, device coordination for smart meeting rooms and distributed speech transcription for meetings. It has also been used extensively by Mantara for high-volume financial transaction routing.

Elvin has picked up in so many applications because of its lightweight approach and flexibility. See the examples page to see how it can be employed.
