Geoff, I think I am beginning to undestand what you are suggesting.
Right now I am in process of implementing this setup. At this point nothing exits - no ProjectD, no PartA and no PartB. So I will try to summarize what I have undestood so far: 1. All our SVN repositories lives under the following location: \\myserver\SVN_Repositories\ProjectA<file://myserver/SVN_Repositories/ProjectA> \\myserver\SVN_Repositories\ProjectB<file://myserver/SVN_Repositories/ProjectB> \\myserver\SVN_Repositories\ProjectC<file://myserver/SVN_Repositories/ProjectC> 2. Now each of the Project directories - Project A, Project B and Project C are SVN repositories of their own (TortoiseSVN->Create Repository here) 3. Now Mr. ProjectD comes along with has two sub-parts - PartA and PartB. So I create a new repository ProjectD (TortoiseSVN->Create Repository here) under this (correct?): \\myserver\SVN_Repositories\ProjectD<file://myserver/SVN_Repositories/ProjectD> and then create two directories (with their own tags, branches and trunk) underneath ProjectD (all using SVN commands) like this: \\myserver\SVN_Repositories\ProjectD\PartA\trunk<file://myserver/SVN_Repositories/ProjectD/PartA/trunk> \\myserver\SVN_Repositories\ProjectD\PartA\tags<file://myserver/SVN_Repositories/ProjectD/PartA/tags> \\myserver\SVN_Repositories\ProjectD\PartA\branches<file://myserver/SVN_Repositories/ProjectD/PartA/branches> \\myserver\SVN_Repositories\ProjectD\PartB\trunk<file://myserver/SVN_Repositories/ProjectD/PartB/trunk> \\myserver\SVN_Repositories\ProjectD\PartB\tags<file://myserver/SVN_Repositories/ProjectD/PartB/tags> \\myserver\SVN_Repositories\ProjectD\PartB\branches<file://myserver/SVN_Repositories/ProjectD/PartB/branches> Note that Part A and Part B are not their individual repositories. They are just directories that live under ProjectD which is a repository. 4. Let's say now PartA and PartB code development begings and at some point a tag is created for each of their release: \\myserver\SVN_Repositories\ProjectD\PartA\tags\REL-1.0<file://myserver/SVN_Repositories/ProjectD/PartA/tags/REL-1.0> \\myserver\SVN_Repositories\ProjectD\PartB\tags\REL-1.0<file://myserver/SVN_Repositories/ProjectD/PartB/tags/REL-1.0> Now let's say the output of Part A - PartA.xcf and output of Part B - PartB.xcf are concatenated into a file called PartAB-R1.xcf. My questions: Q1. At this point I would somehow like to store this file (PartAB-R1.xcf) into my SVN repository (ProjectD). What would be an ideal location (logically) to store such a file. Should I be doing any kind of merging from tags (REL1.0) of PartA and PartB to create another node called "Combined-REL-1.0" or something like that. I would like to avoid this if possible. Q2. Also when somebody checks out ProjectD I would like that it pulls the PartA and PartB revision history also so that users cab see the "Revision Graph" of PartA and PartB together using the TortoiseSVN client. I hope I am able to describe the whole scenario to you all.
