Hey Petr- I've actually been working on a similar project for OCAL for the past few months, and vividly recall working through the issues you're describing. You can check out the code at <a href="http://developer.berlios.de/project/showfiles.php?group_id=4098">http://developer.berlios.de/project/showfiles.php?group_id=4098</a> and search this mailing list and the Inkscape developers list (at <a href="http://sourceforge.net/mailarchive/forum.php?forum_id=36054">http://sourceforge.net/mailarchive/forum.php?forum_id=36054</a> ) for "clipart browser" to get a sense of where the project is. There's also a screenshot and some other notes at <a href="http://summerofclipart.blogspot.com">http://summerofclipart.blogspot.com</a> . Ironically, my code was initially designed as an Inkscape extension, analagous to what you're doing, but was made into a standalone program in the hope that it would be usable by other projects as well, very specifically including Scribus. Check out the code; its also in python, and a lot of the features you're trying to add have already been implemented, and its been through several releases and a bit of testing already. There's some bad news of course; it uses GTK, instead of QT, but that's not an insurmountable problem. If you'd like to get integrated into Scribus' extension system (since Scribus 1.3.0 doesn't appear to support drag-drop or copy-paste of SVG images from external programs), I'd be glad to help, and even if not, a lot of the code could be reused, such as the metadata parser.
