It appears that the two databases (if there are two) are linked together. Since Mundia.com is apparently still in its Beta testing period, it is still free. The last blog post to the Mundia Blog was on 17 May 2011. It has all the appearances of a program that is in the throes of being abandoned.
It is interesting that there are these bits and pieces floating around on the Web. I couldn't find any significant mention of the program since sometime last year.
