Hello Jeroen ,
can i get from your words that this page : http://www.wikidata.org/wiki/Special:ListDatatypes is not up to date ?if so how can i get all the datatypes in Wikidata ?
but what i can get is list of datatypes available , these has to be the way of representation of data (like the lower level ) not the semantic datatype of the thing .
so it's either an item or string or common media file or time or geolocation
string could be anything ( so time could be a string) , but there's a defined lower level representation of common media files . so is it wrong to represent it as string ,
thanks Regards

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
