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
