Jan 13, 2010 at 5:03 comment added Mariano Suárez-Álvarez Yes, but only taking isometric embeddings results in a weaker universal property. One could ask: if $\mathbf{Met}$ is the category of metric spaces and continuous maps, what subcategories $\mathbf{Met}'$ of $\mathbf{Met}$ containing all objects have the property that their full subcategory spanned by the objects which are complete is reflective?
Jan 13, 2010 at 4:40 comment added Pete L. Clark OK, I can see that I will have to have a look at Mac Lane's book (I assume you mean Categories For the Working Mathematician). But isn't everything you said true with "uniformly continuous map" replaced by "isometric embedding"?
