Maybe I can shed a bit more light on this issue. The DTN feed
"describes" itself to whatever data "server" is receiving it,
using a sort of master configuration file. This way, as DTN
makes changes to its data structure, a well-written server
can simply keep up with those changes by consulting the new
configuration file, which DTN can easily transmit as often
as necessary. This is basic software-development 101 stuff,
and is called "indirection," because you get to your goal
indirectly by going through an intermediate description.
The latest change involved adding a new field to the basic
data structure, and yes, it was announced to the world back
on Sept 19 by DTN, with the usual invitation to let DTN know
if the change would cause anyone any problems.
A well-written server would presumably be able to cope with
a change in the number of data fields, even if it could do
nothing with the new fields but benignly ignore them.
Sounds like some servers don't qualify as well-written... :)
