Hi there,
can you elaborate a little bit more on what are you trying to achieve.
It's almost impossible to help with that generic description.

You can write rules on your products that create and insert new facts pretty easily

Rule "categorize product"
  no-loop
  when
     $p:Product(name == "Product1")
  then
     $p.setCategory("category1");
     update($p);
end

This rule will enrich your original product with a category depending on the product name. Are you looking to something similar to this?

Cheers
