In Germany maybe you could deduce that, but in other areas it could be read as [PostalCodePrincipal]-[PostalCodeSecondary]

Context is relevant.

Hi Patrick,

If you know that Wikipedia/DBpedia keeps zip/postal codes as a range you can split the postal codes at "," (since postal codes are not
continuous) and infer that "-" implies a range. That goes a bit beyond the simplicity I assumed, of course.

Another problem: Bremerhaven is a part of the state of Bremen but is not the part of the town Bremen. I don't know if this is covered by DBpedia.

Wikipedia/DBpedia does a good job, but you may infer much more information. And even if we treat postal codes right, we'd get the feedback that XY is treated wrong in our mapping. :) But we can adjust our mapping.

Best regards,
Lars
