Upcoming railML 3.1 does not consider macroscopic infrastructure
elements on a generic basis. Instead, every infrastructure component
uses its own dedicated data type. However, few aspects of macroscopic
infrastructure elements have been implemented:
* Location
Every infrastructure element can be placed very flexible within the
topology network: Spot locations, linear locations and area locations
may even exist in parallel and define different spatial aspects on
different modeling levels of detail.
* Hierarchy
Elements of same type can be put in a hierarchical order. In particular,
an infrastructure element may reference its one and only parent
infrastructure element using the attribute @belongsToParent. Such a
reference attribute is available for example for platforms, operational
points, signals, level crossings and lines.
The complex infrastructure elements adressed in Trac ticket [1] will be
analysed in detail with the "Advanced Example" together with a future
railML 3.x version.
Of course, any comments on this topic are highly appreciated...
