Why do you want to do that?
I could imagine applying JCR to an existing file system (e.g. SVN layer)
AFAIK http://jackrabbit.apache.org/jackrabbit-spi.html allows to do
something like this.
Or do I misunderstand Jackrabbit SPI?
Thanks

The generation of the UUID is implementation specific. You can get it with
getUUID() (for mix:referenceable nodes) or with getIdentifier() (in JCR
2.0). But in most cases when you model content or use the JCR API you want
to use paths instead of UUIDs:
http://wiki.apache.org/jackrabbit/DavidsModel#Rule_.237:_ID.27s_are_evil.
And how nodes and properties are stored on the file system is an
implementation detail of the persistence manager. You should use the JCR
API to access things, just as you don't access the database files of a
RDBMS.
