I agree; thanks for the pointer, I just added them as enhancement
requests for Conglomerate to Bugzilla:


Unfortunately the Papyrus XML format seems to lack both a namespace and
a DTD, which makes it trickier to support within Conglomerate (it has to
try and guess what XML doctype it's looking at).  But it's still

I agree, looks like a good fit, though ideally I'd want to make some
changes to the details of Papyrus' XML format.  It also doesn't seem to
leverage XSLT; perhaps this could be used to add output->AbiWord and
output->OO.org etc.

Within Conglomerate we could have support for editing Papyrus XML files,
and a "Generate Report" option in the menus; these would be fairly easy
to add using a plugin (maybe a 1 hour job for someone who knows our

I don't really care about what database abstraction layer is in use etc,
I just want a sane XML format that describes how to generate the report,
ideally some kind of standardised one supported by multiple projects.

I'm not really a "database person", though so this stuff is low-priority
for me, I'm afraid.  But I'll happily accept patches :-)
