ASU was very much in our minds as we considered specifying the cone search.
For me, I first read the paper in 1997. But ASU gives the *client* a lot of
freedom -- different coordinate systems, SQL queries, Julian dates etc.
Therefore it would take a lot longer for the *publisher* to build an ASU
server from zero than building a cone search server from zero.
The point of the cone search prototype is to see how many data publishers we
can get on the same page, not the sophistication of the interface that they
implement. There have been several VO prototypes for distributed data
publishing, but it seems that if the step is higher than 2 cm, nobody except
the developer seems to get involved. So we experiment with making the step 1
So far we have 9 people in the registry. That is the "new wheels".
