What are the disadvantages of using NeTEx?

NeTEx is not a panacea and there are also a number of potential disadvantages to using it

  • Additional complexity from using a large, generalised model. See ‘Is NeTEx hard to understand?’
  • Fragmentation of semantics from generality see ‘Does increased generality make NeTEx is harder to work with?
  • ‘Addition computational expense for processing large XML models with extensive integrity checks..
  • Limited expressiveness of XML
  • Slow speed of standards process
