I think WKT literal should specify the coordinate system, otherwise it becomes essentially useless - you can not do any queries on in if the literal may mean something on Earth or something on the Moon. If you query "give me items in within 50-mile radius of Paris" and get a moon crater - this is useless. Thus, the literal should allow to distinguish between them. This has nothin to do with defining CRSes, in which we have no business, or with definiting geometries, which we don't do either. Proper software libraries that handle WKT should also be able to handle requirements of OGC standards. If they do not, they can't handle non-Earth coordinates anyway, so it's better for them not being able to parse them than parse them and think moon crater is in Paris. Explicit failure is always better than garbage data. > if a Wikidata goal is to introduce more complex GIS spatial data We'll cross that bridge when we get to it.
