I am building a web site for knowledge discovery, and would like to understand more the structure of wikidata in order to expose selected keys for a wikidata object.
Is there any schema describing all the keys used in wikidata objects?
As example, this demo shows all possible keys for 'Richard_Feynman' object.
It looks like that for each property belonging to 'Richard_Feynman' a query must be made against the property_Id , so to fetch a human readable label.
That is, about ~500Kb must be downloaded. I would like to understand better how to consume wikidata API.
- which API exposes a simple schema 'key' : 'value' , like: 'birth_date' : 'Los Angeles' (similar to what you see at wikidata site) ?
- which API expose the value of a relationships between objects ? (e.g. Feynman is connected to Cornell University by 'employer' relationship)
- Is there a table describing all keys currently present in wikidata, so that is possible to know which one to filter ?
thank you for your debrief,
