For example, if I wanted to know what the product/coproduct is in a certain category, I could find it on that site. I commonly come across websites (such as wikipedia) that give a few examples of some categorical concept. I would like a site with a large database which is constantly updated.
Is there a website dedicated to the application of Category Theory to different branches of Mathematics?
