3.12. TC PUSH

TC PUSH presented the recent work of the Technical Committee. The first piece has been a schema to allow servers to advertise supported push transports. A brief introduction was done into some of th existing push concepts for those not familiar with some of the terms and technologies. The TC presented three different scenarios for push and how they differ when it comes to subscribing to change notifications for a resource. It was pointed out that vendors are unlikely to change their (existing) push implementation, and we discussed the concept of a push gateway that abstracts from the actual push transport and provides a standardized push interface to application servers.
