Thinking About Tags [en]

What if taggy applications like Technorati, Flickr and Del.icio.us started allowing us to query multiple tags with “and” and “or” operators?

[fr] Une proposition pour pouvoir combiner les tags (comme "blogosphere ET blogosphère", "livres OU films") dans des services comme Flickr, Del.icio.us, et maintenant Technorati.

Some quick thoughts about tags, following Technorati Tagified.

So, there is “blog“. And “weblog“. And “blogs“. And “weblogs“.

How about a way to get the posts/photos/links tagged with any of these tags? Maybe something like .../blog,blogs,weblog,weblogs/.

That would also solve some multilingual problems: get “blogosphere” and “blogosphère” together on the same page with .../blogosphère,blogosphere/.

At del.icio.us, I tag the books I’ve read with “books/read“, and films I’ve seen with either “films/seen/cinema” or “films/seen” (if I saw them on DVD). This used to work fine, because a del.icio.us bug (poor me thought it was a feature) would include links tagged as “films/seen/cinema” when one asked for “films/seen“. That doesn’t work anymore.

Say I avoid messing with tags-with-slashes, and tag films I saw at the cinema with “films seen cinema” and others with “films seen dvd”. I’ll probably also have links tagged “films” or “cinema” but which are not tagged “seen”. How could I pull out a list of links tagged “films” AND “seen”? Perhaps something like .../films+seen/.

Update, 10:00: Kevin tells me “+” signifies a space in a URL. Maybe “&” could do the job instead, then? And if “&” can’t because it’s supposed to separate parameters, any other suggestions?

Update, 11:40: holy cow, Del.icio.us does this already! I’ve updated my tags and lists. See “books+read” for books I’ve read, and “films+seen” for films I’ve seen. I’m a happy bunny!

Let’s get wild, shall we? .../books-read/ could list things tagged as “books” but not “read”.

Now we only need a way to assign operation priority, to be able to start retrieving lists like “books I’ve read or films I’ve seen which are also tagged as india” — wouldn’t that be cool?

Taggy application developers, hear the call!

Thanks to rvr and GabeW for the little discussion on #joiito which prompted me to write this post.

P.S.: has anybody written that WordPress plugin yet? (You know the one I’m talking about: the one that lets you painlessly technorati-tag your posts.)
