[OSM-dev] multipolygon relation and non-closed ways

[Pedro Larroy]

Hi

I'm processing multipolygon relations and finding a lot of unclosed
ways while processing spain.  The wiki says ways in multipolygon
relations are closed.
http://wiki.openstreetmap.org/wiki/Relation:multipolygon

For example, way 157464286  of rio Mino which is unclosed ( member of
multipolygon relation id 2909). Many multipolygon relations has a
mixture of closed and unclosed ways.

Is this expected or are errors in the data?


Pedro.
