I couldn't come up with anything better.<br><br>Continuing to learn my way through "relations" and assorted "tags",<br>I came across relation=3489649 [0], island of Oahu, HI, USA. What<br>interests me is its "way" member=428362225 (Way: War Memorial World<br>War II) [1] with role="".<br><br>It seems that this association is a mistake. If so, is there a<br>better place to report these sort of things as I come across them?<br>As I am still learning my way through the data, I don't wish to<br>do wholesale edits.<br><br>Question: Is there a general rule used when processing role=""?<br>OSM wiki for Relation [3] indicates that roles are optional. It<br>looks that OSM is rendering way=428362225 as an area [4].<br><br>Thanks in advance,<br>--patrick<br><br><br>[0] <a class="edited-link-editor" id="yui_3_16_0_1_1474254890384_8268" href="http://www.openstreetmap.org/relation/3489649" target="_blank">http://www.openstreetmap.org/relation/3489649</a><br>[1] <a id="yui_3_16_0_1_1474254890384_8269" href="http://www.openstreetmap.org/way/428362225" target="_blank">http://www.openstreetmap.org/way/428362225</a><br>[3] <a id="yui_3_16_0_1_1474254890384_8270" href="http://wiki.openstreetmap.org/wiki/Relation" target="_blank">http://wiki.openstreetmap.org/wiki/Relation</a><br>[4] <a id="yui_3_16_0_1_1474254890384_8271" href="http://www.openstreetmap.org/relation/3489649#map=19/21.59777/-158.10302" target="_blank">http://www.openstreetmap.org/relation/3489649#map=19/21.59777/-158.10302</a><br><br>_______________________________________________<br>dev mailing list<br><a ymailto="mailto:dev@openstreetmap.org" href="mailto:dev@openstreetmap.org">dev@openstreetmap.org</a><br><a href="https://lists.openstreetmap.org/listinfo/dev" target="_blank">https://lists.openstreetmap.org/listinfo/dev</a><br><br><br></div> </div> </div> </div></div></body></html>
