I must say I really don't understand. We are not reinventing  
anything. We are just coming to the realization that there is a  
better transport mechanism that interconnects with large  
visualization engines. VOTable is just no cutting it. No astronomer I  
know want to ever see a VOTable and I think VO is indeed moving in  
the direction of "hiding" VOTables via smart XSLT transformations  
developed for the Hubble Legacy Archive.

not now, let's wait a few years to see where it takes us. I have a  
much more optimistic view, perhaps an utopian view of where we can go.

Let's demystify this: KML *does* support metadata. My argument is  
that KML can do better. WWT's standard might do it even better.

Time will tell.

I'll end this thread, it seems that we have all expressed our views.  
Thanks.


Ciao,
