(Correct me if you know I'm wrong on any of this - I don't use Open
Office so have been starting completely from scratch and had to
believe what I read on the internet...)
I've done some looking into this and Open Office really has lousy
support for clip art galleries. It also has pretty lousy support for
SVG (via an optional component) but the PNG versions would be a good
starting point at least.
Essentially, Open Office doesn't really support any metadata on
clipart beyond just grouping them into separate galleries (think
folders). So we'd need to build a gallery of animals, one for people,
one for buildings etc. That's doable though, but not going to
leverage most of the metadata that open clipart is collecting.
There are however a few key problems with distributing galleries in
1. You need to create a .sdg, .sdv and .thm file to go with it. These
are proprietary binary files and there's very little tooling or
documentation on them. The easiest way to build them is to use Open
Office itself to create a gallery and then copy the resulting files out.
2. Those files are named sgXXX.sdg where XXX is a number that needs to
be unique. Managing installs where the filename might not be unique
and also managing upgrades needs to be added to the scope.
Once you get over those issues, the package format is a pretty simple
zip file but with a .oxt extension and it contains a few XML files to
Interestingly there are prebuilt packages for Mandriva and Ubuntu
(openclipart-openoffice.org). Anyone know where these came from as
they seem to be the best starting point?
