[wp-hackers] plugin development: adding my own URLs and handling them?

[Michel Valdrighi]

Hello,

Since this is what I want for my blog, I have started developping a
tags plugin that uses its own table instead of metas, and should grok
URLs like example.com/blog/tag/stuff, where 'stuff' is the name of a
tag. Eventually I'd like to propose this for the core WP in a future
version.
I'm doing fine with most of the coding, and I see that there is now a
hook to the rewrite rules (whoever++).

Except before I'm going further with the URLs stuff, I would like to
know if it's possible to handle the URLs added with the hook; since
I'm rather WP-Query-illiterate at the moment.

Thanks in advance for any hindsight.
