For on project in the repository I would recommend you
https:/code.aaa.bbb/svn/Repo001/trunk
if there is more than one project in repository then:
https:/code.aaa.bbb/svn/Repo001/projectName/trunk
In our projects we use "stantdard-structure" with trunk
, branches
and tags
. Works fine and new teammember who formally worked with svn understand the structure and "the way to use" quickly.
