Overpass API developpement

[Jo <>]

Hi,

I've written a Lua module to query Overpass API from Wikipedia.

https://en.wikipedia.org/wiki/Module:OSM

I deployed it on nl, en and fr.

I got a remark about queries using regular expressions to retrieve multiple wikidata Q-numbers.

The second test case produces the following query:
(
node["wikidata"~"[Q650206|Q713300]"];
way["wikidata"~"[Q650206|Q713300]"];
relation["wikidata"~"[Q650206|Q713300]"];
);
out;
>;
out meta qt;

which takes forever to complete and eventually times out. A solution would be to add a bbox. But this is a relatively simple case and it's unfortunate it doesn't work.

The other remark is that the query is too general and would give wrong results for shorter Q-numbers, which is correct. So I came up with the following:

(
node["wikidata"~"[Q650206(;.+|$)|Q713300(;.+|$)]"];
way["wikidata"~"[Q650206(;.+|$)|Q713300(;.+|$)]"];
relation["wikidata"~"[Q650206(;.+|$)|Q713300(;.+|$)]"];
);
out;
>;
out meta qt;

which times out as well.

I must be doing something wrong, but I can't seem to figure out what it is.

Anyway, the module should make it easier to find streets named after persons or cities. (If they already have wikidata tags, that is).
