Dear all,

upcoming new major version railML 3.x will contain lot of modifications
and changes. In order to keep a unified layout and model structure, some
elementary "Data Modelling Patterns" have been defined. These patterns
shall represent a set of rules for modellers (and users) how certain
things are being structured in the model. You can find a first version
of these "Data Modelling Patterns" in [1].

I would like to get your feedback on this approach: Do you agree with
the overall concept of having Data Modelling Patterns? What do you think
about the different patterns in particular?

Any reaction is highly appreciated...

[1] file replaced by newer version on August 17th, 2018

Best regards
Christian

Dear all,

there is a new draft version of the "Data Modelling Patterns" document
available in [2]. The following small changes have been incorporated:
* adding pattern "Names of elements and attributes"
* clarification on Element vs attribute
* clarification on preferred solution for pattern "Boolean information"

Any reaction is highly appreciated...
