Versions & Licences

The development of the early alpha versions started in 2001. Version 1.0, the first version allotted for productive use, was published in 2005. In 2019, the development was forked into the established railML®2 family and the new railML®3 family. railML®3 differs from railML®2 in many features and therefore is not designed backward compatible. The most fundamental difference is difficult to recognize at the surface: It is based on RailTopoModel®, thus incorporating a sophisticated topology model in the background. The current railML®2 version is 2.4, published in 2018. The current railML®3 version is 3.1, published in 2019. All currently supported railML® versions are licensed dually free under a restricted form of the Creative Commons licence (external link) CC-BY-NC-ND and (for certified programmes) in free a commercial licence. To learn more about the licence terms see https://www.railml.org/en/user/licence.html (link to the railML® website).

A detailed version list can be found on https://www.railml.org/en/developer/version-timeline.html (link to the railML® website).

Schema changes in older railML versions / Other information sources

It is not intended to describe changes between minor versions in railML 1 as there are no records from the pre-SVN time. Also changes between the major releases (railML 1 > railML 2 or railML 2 > railML 3) could not described here, as there are to much structural and major changes in railML.
