Dear all,
Since I'm new to RailML community I introduce myself: I'm Fabrizio Cosso from Ansaldo STS and I'm following standardization activities. I'm trying to familiarize with the railMLv3 model.
In the Concept Location class diagram there are associations from RTM classes to railML classes (i.e. RTM_SpotLocation associated to SpotLocationOnTrack).
Generally speaking is it correct to create an association originating from RTM model towards railML classes? I would expect link in the opposite direction.

Thanks a lot,

Regards,

Fabrizio Cosso

Dear Fabrizio,
dear all,

the issue has been solved with railML 3.1 beta. There is no further
association from a RTM based class to a pure railML class.

Best regards
Christian

Dear all,
I might be wrong but to me it (associations from rtm to railml classes) seems to be still there, isn't it?

Please have a look on a screenshot of the aforementioned diagram in the current railML v3.1 beta model:

The class Entity is not a RTM class, but derived from
RTM_LocatedNetEntity. Therefore, the extension (references to
GmlLocations etc.) is made from a railML class and not from a RTM class.

From content point of view you are right: While RTM does not have
references to specific location extensions like GML or track, railML
model has. However, considering the introduction of length information
in RTM NetElement as described in forum entry [1], a reference to
"trackPosition" and "trackSection" is no longer needed and can be
removed from the model. Further, in forum entry [2] I suggested to
introduce NetworkLocation as new RTM EntityLocation sub-class.
