Hi Denny,

I am sorry, but I have to voice some criticism of this project. Over the 
past two years, I have become increasingly wary of the excitement over large 
numbers of triples in the LOD community. Large numbers of triples don't mean 
don't necessarily mean that a dataset enables us to do anything novel or 
significantly useful. I think there should be a shift from focusing on 
quantity to focusing on quality and usefulness.

Now the project you describe seems to be well-made, but it also exemplifies 
this problem to a degree that I have not seen before. You basically 
published a huge dataset of numbers, for the sake of producing a large 
number of triples. Your announcement mainly emphasis on how huge the dataset 
is, and the corresponding paper does the same. The paper gives a few 
application scenarios, I quote

"The added value of the paradigm shift initiated by our work cannot be 
By endowing numbers with an own identity, the linked open data cloud
will become treasure trove for a variety of disciplines. By using elaborate 
mining techniques, groundbreaking insights about deep mathematical 
can be obtained. As an example, using our sample dataset, we were able
to discover that there are signicantly more odd primes than even ones, and
even more excitingly a number contains 2 as a prime factor exactly if its
successor does not."

I am sorry, but this  sounds a bit overenthusiastic. I see no paradigm 
shift, and I also don't see why your findings about prime numbers required 
you to publish the dataset as linked data. I also have troubles seeing the 
practical value of looking at the resource pages for each number with a 
linked data browser, but I am also not a mathematician.

I am sorry for being a bit antagonistic, but we as a community should really 
try not to be seduced too easily by publishing ever-larger numbers of
