Reg: How to fetch the sub properties and properties - Wikidata

11 Mar 2021

Hi,

Is there a way to get the child properties/sub-properties of a property?

Example: position_held(P39) property has sub-properties like start time 
and end time so how to get them directly with SPARQL query and also If I 
have a wiki dump which is around 65 GB so how to parse a huge wiki dump 
and get the properties and their related sub-properties?

I got all the property IDs and property labels by SPARQL query but its 
inner properties like start time, end time.. so on were missed.

Thanks in advance!!

Thanks and Regards,
