>
> DocumentNodeStore does not currently check which software version the
> persisted repository it is connecting to was created with or last updated.
> There is a risk that if the versions are incompatible the repository may be
> damaged.
> Somewhere in the repository, the version of the software that created it, and
> the versions that written to it should be stored. In the case of TarMK this
> information could be on local disk near the TarMK files. In the case of a
> DocumentMK implementation, the information should be stored in the "database"
> itself.
> When a DocumentNodeStore instance connects it should: check the versions
> stored in the repository then check the versions are within a compatible
> range and refuse to start if not.
> When a DocumentNodeStore writes to a repository, it should add its version to
> the list of versions that have updated the repository.
> This check behaviour should be active in full Oak or any utilities (eg
> oak-run).
