Yes, for primary data storage (though roundtripping via limited-precision doubles is not ideal, but I guess good enough for now). But for secondary data/query interface, I am not sure 0.333333333 is that useful. What would one do with it, especially in SPARQL? -- Stas Malyshev [email protected] _______________________________________________ Wikidata mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikidata
