[Developers] MQL license?

[Roland Bouman]

Hi All!

I am new to freebase and MQL, and I just got terribly excited
downloading freebase datasets and reading the MQL specification.
I have a few questions, which I decided to join the list. I apologize
in advance if my questions are answered elsewhere, but I haven't been
able to find the answers yet.

Currently, I'm wondering about the legal status regarding the usage of
MQL in applications.
In particular, I'd like to know whether I can create applications that
use the MQL query language and/or implement MQL on top of some
datastore (not freebase).
I haven't been able to figure out whether such applications would
violate some patent or would be considered illegal use of intellectual
property.

I appreciate your answer,

thanks in advance and kind regards,
