Currently there is no notion for .. and . in Oak paths and I would leave 
it at that. I.e. oak-jcr needs to take care to normalize paths before it 
passes them to the Oak API. But of course we should use the 
JcrPathParser to do that.

The JcrPathParser does already normalise. What it can't do is 
normalising "negative" paths like ../foo or foo/../..

See my other mail how that could be handled with the current setup. 
Alternatively we could also have the JcrPathParser accept a prefix path 
against which normalisation is done.

In the sense I described above yes.
