I wish to host my bookmarks on my webspace now. Am hosting with Dreamhost (MySQL/PHP/Python/Perl…etc). Want code with 1)freeform multiple tagging 2)nice selection filter(ALL flash AND word-games BUT NOT anagrams OR java) and quick search. You get the idea. 3)Ability to set ‘shared’ and ‘private’ access. Bonus points for three options i.e. bookmarks visible only with my password, those visible by all, and those accessible by others with “guest” privileges. I looked at Yahoo! directory. Most seem to be hosts like furl or del.icio.us, not apps.
I wouldn’t mind the app to also support notes with hyperlinks, but that’s not so important. Ideal situation would be cross-referencing, i.e. say each link has an unique ID in the Db -> #667 (www.metafilter.com). So, I can compose notes like:
Some good community blogs are [link id=667]Metafilter[/link] and [link id=872]Monkeyfilter[/link].
Now, in the bookmarks mode, when I display entry 667, there’s a trackback: this link is referenced in [note id=233]Note Title[/note] and [note id=592]Note Title[/note].
Yes, that sort of thing. But I don’t see any app offering close to what I’d like. Any others?
How long does it take to write a bookmark app in PHP/Python?
Not really sure, as I’ve never even heard of a “bookmark app” 
Sounds like you want a really specific thing, so it might be best to write it yourself.
But it really depends on your proficiency in PHP, ya know? I could probably sit down and do it in a weekend, but that sort of thing is what I do for a living so I would already know what to do. I have no idea what you know.
If you DON’T know PHP and want to learn, there’s tons of free resources as well as books - this could be a very good opportunity to learn. You could get one of the free scripts you can find online then re-construct parts of it to work like you want. Basically you need a good DB structue that allows for IDs, Names, Links, Categories and Descriptions. Then you need to be able to maniplulate the queries that are used to display the data based on what you’ve clicked (sort, category ID, etc) As for making hotlinks out of words you just need to run a replace function on all your text that will sniff out anything found in your Name column and replace it with [a href links.php?id=#]name[/a]
As another option you could always put it up as a project on www.elance.com You’d have to pay someone to do it but bidding is getting pretty competetive over there and you might get it cheap. Sounds like you really want this so it might be worth a few $$ to you to get it done.
(sorry no I don’t do PHP so I can’t bid on it 
)
