dm-svn allows you to store data in a Subversion repository, then sync that data to a DataMapper model (for example, to a relational database. Essentially, it allows you app quicker access to the Subversion data.

Given a Subversion repository, svn-transform creates a new repo that is by default identical, but allows changes to files, for example all or some of the properties on each file can be moved from the properties to YAML prepended to the body of the file. Primarily useful prior to conversions to other repository types such as git.
