[Data-modeling] Hormone type in the Medicine domain

[Faye Li]

Hi,

The Human Hormone and related types are ready for review on Sandbox:
http://sandbox.freebase.com/view/medicine/human_hormone

The new types are:
- Human Hormone (named such to avoid mistyping of plant or animal hormones)
- Hormone Chemical Classification
- Endocrine Gland
- Hormone Receptor
- Receptor Family

In the interest of getting this out there soon I'm avoiding modeling 
more complex relationships. Related diseases are the next step I think, 
although there's plenty more to do. I've filled in some data to see how 
the schema fits.

A medical shout-out: I have to admit I got a little tangled trying to 
parse the myriad of medical endocrinology info on the web. Seems that 
even something as basic as defining the types of Hormone Chemical 
Classification is debated: Wikipedia says there are 3 kinds, whereas 
other web sites claim 4 or 5 (adding Lipid and sometimes Sterol to the 
list consisting of 1. amine, 2. peptide (& protein?), and 3. steroid). 
Also, is a Hormone Receptor always or pretty much always a Gene? We have 
a Gene type in the Biology domain that I'd be more than happy to add as 
an Included Type if it makes sense. Medical review of the type and 
property names would also be appreciated.

Thanks,
-- Faye
