category for organizations and products

Hi,


 As a website author, publishing product and organization (local business
corporation etc.) "category" are important for me.


Do you plan to add a property about ISIC and/or NACE, NAICS code(s) to
http://schema.org/Organization? (All companies are officially categorized
with NACE codes in Turkey)


Some vague but, publishing "category" property for product is also
important i think.


Best,
