MQL query to get all properties for the particular MID in Freebase - semantic-web

Question

Take a look at this MID "/m/02r4n63" of freebase. Question is how to get all the properties related to this MID.
Freebase page for this MID.
I need to extract all the properties like director, producer, starring, etc from this page.
I tried these queries in endpoint
{
"*": null,
"type": "/film/film",
"id": "/m/02r4n63"
}
Output of above query gives properties related to /film/film only and gives starring list as null.
I tried this one
[{
"master_property": {
"name": null,
"id": null
},
"source": {
"mid": "/m/02r4n63"
},
"target": null,
"target_value": null,
"type": "/type/link"
}]
Output of above query misses out /film/starring property.
I also tried
{
"id": "/m/01jrbb",
"/type/reflect/any_master": [{
"id": null,
"link": {
"master_property": {
"id": null,
"name": null
},
"target": null,
"target_value": null
}
}],
"/type/reflect/any_value": [{
"link": {
"master_property": {
"id": null,
"name": null
},
"target": null,
"target_value": null
}
}],
"/type/reflect/any_reverse": [{
"id": null,
"link": {
"master_property": {
"reverse_property": {
"id": null,
"key": null,
"name": null
}
}
}
}]
}
But again it misses out properties like Description.
I want to cover all the properties.
I tried the topic search API already. That's the output I want. But I want it through MQL query as I need the names of the properties too.
Help is highly appreciated.

The Topic API is the best way to get all information about a given topic:
https://www.googleapis.com/freebase/v1/topic/m/02r4n63
You can get the name of a property using MQL e.g.:
{
"name": null,
"id": "/film/film/starring"
}
which will return "Performances". Of course, these are mostly going to be properties that you've seen before, so you'll probably want to either cache them or just pre-populate a static list.
If you want "starring", you can just split the key returned and take the last slash (/) delimited segment.
