I will extend this question to:
- So I can ignore "unit" - keys in quantity values too (at least as for
now)?
Yes. Units will most likely be represented by Wikidata entities at some
point, similar to the globe or preferred calendar models, but the
details are not known yet.
- will "wikibase-entityid"s (in the WDTK: EntityIdValue) only be of
"entity-type" "item" (WDTK: ItemIdValue)?
example:
["value",57,
"wikibase-entityid",{"entity-type":"item","numeric-id":353501}]
I have not encountered other versions so far…
For now, all entities in values are items, but having also properties
and other things there is planned (having properties would make sense
once claims on property pages are supported, to relate properties with
each other). So it is ok to support only items for now, but an exception
should be thrown if an unsupported type is encountered.

Hi Fredo,

Hey there,
When I parse the JSON from the dumpfiles, I find coordinates like
{"latitude":51.835,
"longitude":10.785277777778,
"altitude":null,
"precision":0.00027777777777778,
"globe":"http:\/\/www.wikidata.org\/entity\/Q2"}
However the altitude-key is not represented in the WDTK data model. Is
this key deprecated (i.e. should I ignore it when converting dump-JSON
to WDTK-objects)?
Yes, it has been decided some time ago that altitude will not become
part of the geo datatype any time soon. Altitudes will probably be
specified using quantity values (as soon as units of measurement
work). The altitude data in the internal dump format can be ignored
for now.
Cheers,
Markus
