BibSonomyExporter
This tool helps you to export your bookmarks from BibSonomy to del.icio.us and to every social bookmarking site that accepts the Netscape Bookmark file format.
Currently you can trigger these actions:
1. get all your bookmarks from BibSonomy’s webservice and post them to del.icio.us via their API
2. export all bookmarks from BibSonomy into the Netscape Bookmark file format
The first option does everything online: it fetches the bookmarks from BibSonomy and posts them to del.icio.us. If you came from del.icio.us and are now using BibSonomy and want to combine flexibility and popularity of both tools, you could continue using BibSonomy and update your del.icio.us account once in a while. This way you benefit from the great popularity of del.icio.us with its great tool support and the advanced features of a social bookmarking tool like BibSonomy.
