Dear Chengfang,
at the moment our client is able to access data from the WCS server given the following template information: 

<onLine>
   <CI_OnlineResource>
       <linkage>
<URL>http://motherlode.ucar.edu:8080/thredds/wcs/fmrc/NCEP/NAM/Alaska_11km/NCEP-NAM-Alaska_11km_best.ncd? 
</URL>
       </linkage>
       <protocol>
<gco:CharacterString>OGC:WCS-1.0.0-get-coverage</gco:CharacterString> 
       </protocol>
       <name>
           <gco:CharacterString>Total_precipitation</gco:CharacterString>
       </name>
   </CI_OnlineResource>
</onLine>
Anyway we can modify our client to be able to support the format that your server provides.
In general we think it would be interesting to start a discussion on the access metadata topic, to be able to cope 
at best with this part of ISO Metadata specification.
Therefore we have started writing a small document with a few considerations and proposal. We are posting it also to the Galeon list, thinking that it will be of interest. 

We wait for feedback and contributions..!

Hi Enrico,
Do your CSW client can do the WCS GetCoverage operation after the result be returned? 

Currently our CSW can afford WCS linkage with the format of:
