Wow, that escalated quickly ;-)

First of all, for outsides on this list: I do not work with/for DG Move, 
and sadly have been unable to influence them to do more concerning Open 
Data. I invested a lot of (free) time in the time of Siim Kallas, but 
after the change of cabinets have never received an invitation to 
participate in discussions again.

I use it to advocate for decoupling "hosting a file that updates X 
seconds" from "your processes to generate the data". A website today 
also shows the real-time data, by publishing documents. I'm thus mainly 
advocating the Web as a decentralized platform, and to handle real-time 
data in a similar way as we handle other data. The only different thing 
is the fact that these documents change more often.

If real-time data gets a bad name because of that, then that's because 
I've been misunderstood.

Exactly the reason why I believe we should be able to make an 
abstraction from the data exchange specification and the semantics, but 
I guess that's not something we're going to fix in this mail thread

I think they are more or less coming to that within one of their many 
focus points... http://ec.europa.eu/transport/themes_en
