Could you add the original size of the catalog ? We need to see if the 
difference is
very big or not.

For example, here is one of my tests:
gtktalog : 1420654
XML      : 9255334
XML.gz   : 1456885

(the contents are mdk cooker main, mdk cooker contrib and plf cooker)
The difference is only 2.5%: it is not very important.
If such tests show that XML.gz is something like 2.5% bigger than the original 
file
format, I think it is worth using XML.gz: going faster and more extensible, for 
minor
cost supplement.
I did not take time to perform other tests like you.

I have a very important question about your test with gzip and saving gtktalog 
catalogs:
do you use the best compression ratio ? Do you use 9 in gtktalog (see the 
prefs) ? Do
you use the --best or the -9 option with gzip ?

... and it is easier to extend. With the current file format, we break the 
compatibility
for any new feature we want to add.

Well, I need the difference between a gtktalog catalog and an XML.gz catalog 
compressed
with -9 option before concluding anything :)

For the time tests, I "feel" the difference: XML.gz is better :)

Well, either write a sample XML format, or write a DTD. The important is to have
something working :)
If you want to test your DTD:
xmllint --noout --valid --dtdvalid your.dtd.file your.file.xml
Or something similar (man xmllint or xmllint --help :)

Thanks for the test: very interesting yet!
And try the OOo html export: looks good :)
