Subject AW: Etch status (Was: [Incubator Wiki] Update of "March2012" by michaelfitzner)

Hi Jukka,
Thanks for your constructive feedback and the hint to [1]! The establishment of an active
and diverse community is currently one of the challenges in the Etch project. The task is
not so easy because we can do it just beside our main work! As Martijn already mentioned,
we try to publish an article about the Apache Etch Framework for a local (Germany) computer
science magazine. Furthermore I think it would be also good to publish some blog-posts e.g.
at [2] if possible. Another possibility would be to push Etch also in the Android direction
and provide some information how to use it there.

One article worth mentioning:

"Practical experiences on a communication middleware for IP-based in-car networks" [1]

Current in-car communication networks are based on automotive specific technologies like CAN,
FlexRay and MOST and use proprietary communication protocols. While CAN and FlexRay come with
a signal-based communication paradigm, MOST provides a more sophisticated interface based
on "function blocks" to the application programmer. In the next years, we expect IP-based
protocols and standard technologies like Ethernet to be deployed for more and more in-car
communication tasks. As a result, we need an IP-based communication middleware that provides
both signaland function-based interaction paradigms and works for all distributed applications
in vehicles. Main challenges are the large variety of embedded devices and operating systems
used in a single car in terms of footprint and compute power. Furthermore, it must be possible
to migrate existing interface definitions from legacy technologies to the new IP-based solution.
In this paper, we propose an IP-based in-car middleware framework based on an open source
solution, Apache Etch. We sketch how different, yet interoperable versions of the middleware
can be used to construct a scalable system that fits to both small and large devices.
Finally, we identify extensions to Etch that are necessary to qualify the solution for the
use in the automotive domain.
