I would rather hope we map not to UCD but to Data Model terms.
We were rather thinking of this mapping being at perhaps a higherlevel
so skynode would just respond to its own schema but some other portal
would take a query interms of UCDS and rewrite it using appropriate colum names. Another portal might do the same for Data Model terms etc..
So Althoutgh I thinkthe SkyNode must publish its ucds I think any query comming in should be in terms of the proper column names..
