[OSGeo-Edu] Subversion folder strategy for educational material

[Charlie Schweik]

Hi OSGeo edu folks- 

Does anyone have any suggestions on how to set up the Subversion folder
strategy for educational material? We want to be able to store completed
versions and also allow for new releases under development to be
managed. 

We're thinking something like this:

Institution
-- Course name
---- Version 1

But then we see that some programming groups (GRASS, for example) use a
"trunk/branch" strategy. 

Anyone have any advice here? 

Thanks
Charlie
