[Wikidata-l] Properties in Wikidata for Numbers Datatypes

Hello All , i'm working on adding some properties mappings between DBpedia and Wikidata properties [1] when i started to add mappings for DBpedia properties whose datatypes are numbers in the xsd format and some other DBpedia properties that their values are in numbers also but their datatypes in are standard units like : - xsd:Integer - xsd:Float - xsd:Boolean - http://dbpedia.org/datatype/kilogram - http://dbpedia.org/datatype/squareMetre - http://dbpedia.org/datatype/metre i noticed that Wikidata doesn't contain equivalent properties for such DBpedia properties. this includes all properties like : Height , area , weight , mass and population number my Question is, are those properties missing just because no one considered adding them or they don't exist intentionally because Wikidata doesn't have Datatypes for numbers yet ? so for example we are going to see claims in the future on this form ? "m":[ "value", 222, "Integer", 165 ], thanks Regards 1- https://github.com/hadyelsahar/extraction-framework/wiki/Mapping-WikData-to… ------------------------------------------------- Hady El-Sahar Research Assistant Center of Informatics Sciences | Nile University<http://nileuniversity.edu.eg/>
