Hey,
and it's DataType should be "Commons media file" ? not "string" ?
The DataType is not specified in the JSON segment you pasted. It is not stored in entity pages. The "string" indicates the type of DataValue, which is a more low level concept. We have a limited set of these DataValue types, and a potentially much bigger set of DataTypes build on top of that. For instance the DataTypes "integer", "positive integer", "percentage" and "probability" would presumably all use the "number" DataValue.
another Question : should i usually rely on the datatypes written in the
json dumps or should i build and index of wkidata properties and their datatypes to avoid such situation ?
If you need the actual DataType, you will indeed need to build an index with the properties.
Cheers
