Hi all,
Hopefully you guys know that Dasarath came up with a "DOM shim"
implementation based on a "non table" based storage last monday.
(http://svn.apache.org/repos/asf/webservices/axis/trunk/java/dev/scratch/dasarath/)
What he internally uses is link lists. When I went through the code I
felt that it is quite good since it has JDOM like insertion ,skip and
detach capabilities. And since it is deferred parsing the performance
should also be good.
However I am not ready to give up the table concept yet :).It seems
that having several competing prototypes at this stage is no harm. So
I sat about writing a table based ( these tables store data in columns
as opposd to the rows in the earlier model) OM and came up with a
small working prototype. It is not fully functional and is not
complete but sufficient to demonstrate the concept. I will work more
on this prototype (until the end of this week) and try to produce a
complete one.
Ultimate goal in having several protypes(with different approaches) is
to have a comparison and pick the best one (or the best features). So
Chinthaka is writing  a performance test suit based on Sosnoski
software Inc's XML XMLBench Document Model Benchmark. Once these
prototypes are done we can have a perfomace comparison and then decide
which path to take.

Hi Ajith,

The easiest is to create a new Jira issue and attach the code
there .. then post a note asking someone to commit it.
