Freebase GUID return null value on online search
I have some GUIDs extracted from freebase and I am looking for their specific names . When I use online freebase query editor, the engine search just returned me the "mid" of the object. I put some GUID here as a sample.
/guid/9202a8c04000641f800000000081a20e
/guid/9202a8c04000641f8000000000d01105
/guid/9202a8c04000641f8000000000ee5691
I would like to know which query is suitable to retrieve information by having only GUID. I tried
{"id": "/guid/9202a8c04000641f8000000000ee5691",
"name":null,
"*":null}
but the result is empty for some GUIDs like this
"result": [{
"permission": "/boot/all_permission",
"name": null,
"key": [],
"mid": "/m/0838jg",
"guid": "#9202a8c04000641f800000000081a20e",
"timestamp": "2006-10-23T12:41:35.0000Z",
"attribution": "/user/metaweb",
"id": "/m/0838jg",
"creator": "/user/metaweb",
"search": [],
"type": []
}]
}
Thanks
It's possible for Freebase entities to not have a name. This is usually true of the CVT or mediator nodes, but in this case it's a topic which was deleted. If you look at the historical view of the object you can see that it used to be a list of US presidential pets. Freebase excludes Wikipedia list articles (because they don't represent a single entity), so it got deleted.
If you want to query the name as it was before it was deleted, you could use the as_of_time parameter with your query.
EDIT: Here are examples of MQLRead and the query editor
