Re: DODS AS

Hi Joe:

It looks like the main problem is that you want to use "JoinExisting" on 
the variable time, rather than "JoinNew", so:

<aggregation aggType="JoinExisting" serviceName="NAVO" varName="time">
 <fileAccess urlPath="mcsst_k10_20030806.nc"/>
  ...

the coord values are taken from the existing time variable, so you wont 
need the coord attribute; also i removed the serviceName, since they all 
come from the same service, which can be specified in the aggregation 
element.

There may also be a bug with the "null" attribute for JoinNew, which I 
will check. However, I think the above will solve your problem. let me 
know if it does.

Also, I think we still need to upgrade the AS war file in order to do 
some NcML based buoy data, yes? I will try to get a new AS made today 
that you can start using for that purpose...
