Dear Larissa,
dear all,
Thank you for proposing the new semantic constraints IS:006 and IS:014
for railML3. At Bahnkonzept, we specialize in railway infrastructure
surveys, often of only partial lines, and face challenges with the
current constraint IS:014. It assumes definitive start and end values
(@startMeasure and @endMeasure) for a railway line, which isn't always
possible in our operations.
We suggest either providing an alternative to indicate uncertainty in
these measures or considering the removal of this constraint while
retaining IS:006. This adjustment would better support the real-world
scenarios of data providers like us and ensure broader applicability and
accuracy of railML3 data.
We appreciate your attention to this matter and look forward to a
productive discussion.
Best regards,
