#14804 new defect

Unify case handling for boolean tag values

Reported by: michael2402 Owned by: team
Priority: normal Milestone:
Component: Core Version:
Keywords: Cc:


We currently have:

  • OsmUtils#getOsmBoolean() accepting all cases for true, yes, 1, on
  • OsmUtils#isTrue(), OsmUtils#isFalse() accepting lower case true, yes, 1, on
  • OsmPrimitive#isKeyTrue(key) accepting lower case true, yes, 1, on
  • OsmPrimitive#hasAreaTags() accepts only yes
  • Way#isOneway() accepting all cases for true, yes, 1, on and -1, but not reverse
  • Relation map painting respects oneway=-1, but not reverse
  • ReverseWayTagCorrector only accepting lower case, but accepting -1 and reverse

In tests:

  • Highway#testWrongRoundabout: accepting all cases for true, yes, 1, on for oneway, but none of the reversed.
  • UntaggedWay test accepts only noname=yes

That's what I found so far. We should unify this and decide on a common policy here.

  • as input we may accept more, e.g. getOsmBoolean() is base for tag dialogs, which accept many types, but always output yes or no.
  • getOsmBoolean() is the generic function and should be used generally.
  • otherwise we may accept only yes and no in many places (e.g. in drawing and for validity tests).
  • oneway=reverse does not exist. Support of reverse is again one of the "accept many inputs"
  • Why does ReverseWayTagCorrector only accept lower case? It calls OsmUtils#getOsmBoolean()?
  • Generally true/false and on/off aren't really used anymore.


  • Use OsmUtils.
  • Add an isReversedStrict() which does not accept "reverse"
  • Way#isOneway() and painting should use OsmUtils#isReversedStrict()
  • Places using only "yes" and "no" need not necessarily be changed.
  • Maybe add also OsmUtils#getOsmBooleanStrict() only accepting "yes" and "no" (oneway=1 is used thought)
