RE: [TM4J-users] round-tripping

[Kal A. <ka...@te...>]

I haven't used TM4J for a lot of editing and round-tripping topic map files
since the 0.4 release (which was when I added the resourceID concept and the
rest of the plumbing which supports dynamic topic merging). The most tricky
thing was preservation of IDs - and my solution was to not make it an issue
:) - in many ways, the ID assigned to a topic or an association should not
matter, as long as the references are not broken, though of course if some
one has made nice, human-readable IDs for all of their topics it is a bit of
a shame that TM4J currently loses them all in a round-trip. If the topic map
is never merged with another map, then it should be possible to preserve
IDs - it is really just a matter of adding the appropriate options to the
XTMBuilder and XTMWriter classes. Perhaps that is something which needs to
be pushed up the priority list.

If you notice any referential integrity problems after round-tripping the
file, then thats a bug - please let me know of any difficulties like this
that you encounter. I had noticed in the past that merging topicmaps
occasionally generated a bunch of topics with no names, occurrences or
types...and I think that may have been related to the loading sequence
problem. Once again, thanks very much for the helpful bug reports - each of
these bugs has been added as a test into the, currently very small, test
suite so hopefully they should get picked up if a future change causes a
regression.

Cheers,

Kal
