Hello,

This is my first post. I am working at Qnamic in Hägendorf, Switzerland.
Qnamic mainly uses
RailML for exchanging timetable and infrastructure data. Further
information can be found on the
developers page: http://www.railml.org//index.php/developers.html?show=35
Following my thoughts regarding file compression and file name extensions.

1. ZIP
>>> - Do we 'allow' or 'recommend' the compressed RailML files?

From my point of view RailML standard should NOT define whether and how to
use compressed
ZIP archives in context of RailML. It the end it depends on the use-case
whether ZIP compression
shall be used, whether one or multiple files shall be included in a ZIP
file, which algorithm fits best
etc. Defining a standard leads to additional (and in the worst case even
unnecessary)
development effort.

2. File extension
>> - Do we recommend file extensions and if so, which?
>> .railml for uncompressed files
>> .railml.gz for gzipped RailML files (following Unix tradition like
>> .tar.gz or .tar.bz2)

That sounds good to me and follows a common pattern.

Regards
Christian
