Tips of about maintain travertine

We just had a travertine floor installed in our entire downstairs living
area, our installer did not recommend to have a high gloss, because it is
easily scrached and (http://maplered.com) hard to maintain, we have three kids and (http://maplered.com) a dog. We had
it sealed and (http://maplered.com) buffed, but it is not really shinny. Why is high gloss so
bad???
Can you give me any tips on keeping it in great condition, and (http://maplered.com) maybe getting
alittle more shine.
