If you were using only the metadata part, I would have suggested to use 
the formal Apache SIS 1.0 release. But for the CSW part, we are in an 
uncomfortable situation where we have snapshots deployed every night, 
but no formal release. This is because we are focusing all our 
deployment effort on Apache SIS, and Geotk (which still contain CSW) 
became a temporary place for modules not yet migrated to SIS. If you 
don't mind, I suggest to try snapshot for starting. If it works, we can 
try to create a milestone, but it would not be a formal release.

         <dependency>
             <groupId>org.geotoolkit</groupId>
             <artifactId>geotk-client-csw</artifactId>
             <version>5.0-SNAPSHOT</version>
         </dependency>

For the metadata part, it should be sufficient to replace the following 
package names:

    org.geotoolkit.metadata

by:

    org.apache.sis.metadata

Same for org.geotoolkit.referencing, which is replaced by 
org.apache.sis.referencing. Most classes in those packages are about the 
same.

For the CSW, I have been told that this module got a lot of changes (it 
is maintained by another developer). I suggest that you report the 
compiler errors, so we can tell the replacements.

Sorry for the inconvenience,

     Martin
