Hello,
a new document was released: Creating Instructions for railML(R) partial
schemes, Release Candidate 1. Available at
www.railml.org/documents/general/creatinginstructions_ger_RC 1.pdf
The English version will be released within a few days.
Here is a short summary of the content:
- railML(R) is no data modell but a data exchange modell;
- schemes are written in English, according to W3C's XML Scheme Definition;
- comments within the scheme (annotations and element history);
- names conventions for elements and attributes;
- format of date and time;
Not included is the never-ending story about Globally Unique Identifiers
(See discussion articles in group railml.misc for further information.)
Please, send me your comments and ideas via news group. A discussion is
possible only this way. Thank you
Nils Poldrack

Hello,
it's fine to have some guidelines for creating railML schemes.
But I detected some collisions between these rules and the current version
of the infrastructure schema (regarding the rules for the naming of
designators).
[I already posted this in the infrastructure-newsgroup.]
In the current version of "Bildungsvorschrift für railML-Teilschemen"
(Creating Instructions for railML partial
schemes) from Nils Poldrack
(www.railml.org/documents/general/creatinginstructions_ger_R C1.pdf), section
3.5.6 "Bezeichner"/"Abkürzungen" ("designators"/"abbreviations"), there
is(among other) the following rule:
* Abbreviations or contractions may not be used as part of designator names
---> this rule collides with different designators in the infrastructure
schema (e.g. infraAttrGroup, ocp***, dir, posOnNet, absPos, .......)
It's not my opinion that we have to rename these designators, but perhaps we
should change the wording of this rule ("should not" instead of "may not").
Best regards,
Matthias Hengartner

Hello Mr. Hengartner,
thank you for your comment. And sorry, I didn't read all existing
schemes carefully. The published document was a template from Ulrich
Linder. I added some chapters, finished the document, and published it.
But you are right.
That's why I corrected this mistake and published RC2. Available under
the same URL (only RC2 instead of RC1 in file name).
Have a nice day,
Nils Poldrack
