Implementing Dapper for in-situ profile data

[McCann, Mike]

Hi Joe,

Thanks. I see that Thomas responded, I'll respond in another email.

Another question: If I make our profile CTD data available via a
dapper/dods url can it be dapperload'ed so that DChart can access it? 
My initial examination of the dapperload.sh command options and source
code indicates that only EPIC netCDF files can be loaded.

-Mike

	Hi Mike,
	
	Another possibility -- have you spoken to Thomas Loubrieu at Coriolis
about their Dapper compliant server (at http://www.ifremer.fr/dap4cor/
<http://www.ifremer.fr/dap4cor/> ) ? I believe that they store all of
their data in an Oracle database. I'm not sure if the software is
publicly available or not.

		DODS techies,
		
		The discussion over the dapper specification has been interesting to
follow.
		
		I would like to contribute to the discussion, but feel that I need
some experience with implementing a server for our data which reside in
a relational database.  
		
		I know that I could extract the data into EPIC-compliant netCDF files
and load them into dapper with dapperload.sh, but am hoping that there
might be a better way.  I've experimented a bit with the OPeNDAP DRDS
server but don't see how I can write a das/dds to mimic the dapper spec,
viz:
		
		  

			-------------------------------
			
			Profile / Sounding Collection: (same as Dapper "CTD measurements"
example)
			
			 Sequence {
			  lat, lon, time;
			  id;       
			  Sequence {
			    z;		
			    v1, v2, ...
			  } obs;             
			 } profile;         
			
			-------------------------------
			    

		
		Is this possible with DRDS?  Or, is the reason there is so much
discussion regarding the spec is that this capability is in the process
of being implemented?
		
		Some guidance would be welcome and I'd be glad to contribute if I can.
