I'm running Linux at home (and on an external VPS) and it would be trivial to installing the LAMP-stack (Linux, Apache, MySQL, PHP) on any of them... I'm looking for a web-based bookmark handling system, which I can host on my own computer - some PHP-package.
I'm especially looking for something letting me mark bookmarks with tags/keywords, and lets me organize them in a folders-subfolders structure (and it would be extra great if it was possible to let one bookmark-entry, be part of several folders-subfolders). Adding my own description and comments would be great, as would an ability to search for bookmarks by tags, description or comment. It would also be great if it tracked the sites I used often (by going to them from the links), and maybe had a list/cloud of favorite sites accordingly.
Anyway, are there any good bookmark-managers that you can run on your own LAMP-stack? And are there anyone with similar features to what I described?
