[Developers] help - MQL to query by type and get all types

[David Dennis]

Thanks for clearing this up.  I lost interest in working on integrating
Freebase with my site because I spent hours trying to figure out how to do
this.

If I might make a suggestion, a good straightforward intro to give
developers would be example queries for:

1) How to get all topics of a certain name
2) How to get all types for a topic
3) How to get all properties for a type
4) How to get all topics assigned as values for a property

That way developers would know exactly how to explore the full schema.  The
query editor page has a couple of example queries like these at the top, but
they only give half the picture.
