TASK DESCRIPTION

@Nikki noticed these extra triples for some globe coordinate values, e. g. the coordinate location of Kiel:

DESCRIBE <http://www.wikidata.org/value/da11113b27c1aed60f99f8a18c4631b1>

wdv:da11113b27c1aed60f99f8a18c4631b1 a wikibase:GlobecoordinateValue ;
        wikibase:geoLatitude "54.325277777778"^^xsd:decimal ;
        wikibase:geoLatitude "54.325277777778"^^xsd:double ;
        wikibase:geoLongitude "10.140555555556"^^xsd:decimal ;
        wikibase:geoLongitude "10.140555555556"^^xsd:double ;
        wikibase:geoPrecision "0.00027777777777778"^^xsd:decimal ;
        wikibase:geoPrecision "2.7777777777778E-4"^^xsd:double ;
        wikibase:geoGlobe wd:Q2 .

The data type for these three values was changed from xsd:decimal to xsd:double in I34983dffe9 / T179228, but apparently the old triples were never dropped.

I also notice that the xsd:decimal triple does not use scientific notation (which would only be legal for xsd:double), so I’m not sure what’s going on here anyways, given the context of T179228… does that mean that we weren’t actually producing illegal values, and some step in the pipeline transformed the illegal value into the legal version, and therefore the change to double wasn’t even necessary? Or are the xsd:decimal triples coming from somewhere else? I’m confused, sorry.
