Overpass query: how to select unclosed ways that have no tags?

This is what I have until now:

(way({{bbox}}); - way({{bbox}})[~"."~"."];)->.w1;
rel(bw.w1);way(r)->.w2;
(.w1; - .w2;);
(._; >;);
out meta;

But this only selects ways that have no tags and are not part of a relation, so this query gives me untagged areas (closed ways) as well. How can I solve that issue? I know how to do it with other tools, but I need to know if it can be done with Overpass-turbo.

Thanks in advance!

The feature request #197 implies that filtering closed or non-closed ways is currently not possible with Overpass API.

I'd suggest to take a look at JOSM filters instead to do some post processing, more specifically the closed filter. See this blog for details: https://www.mapbox.com/blog/2012-08-15-using-filters-josm/

Basically, that was my question, if it can be done in overpass-turbo or not. Thanks for your answer, it was really helpful!

1	For those googling it's now possible to check for a closed polygon & if there are tags on a way: `way(if:is_closed()==0)(if:count_tags() == 0);` answered 20 Oct '21, 18:08 DaveF 3.3k●84●98●133 accept rate: 16%
