Blogging Tools - multiple categories

Thanks for the response Todd.

Part of the Blogging APIs you have implemented allow for multiple categories to be assigned to a post.
Being able to assign multiple categories to a post is very useful. A post may relate to more than one category, e.g. bookmarks, social networking. With multiple categories assigned to a post a visitor to your site can navigate and find relevant posts more easily. How would you find a post related to social networking if it was only assigned to the category bookmarks?
I've yet to find a blogging client that doesn't support multiple categories.

In the blogging engine I'm working on, categories and tags are the same thing. I was just hoping to use tags but the blogging APIs I'm using do not support this, just categories. An API is just an interface to a site engine, how the engine interprets the data passed in through the API is up to it.

I have to admit, I'm not too fussed about #2, it would just be nice to tag a bookmark and have the post match this information. I can get around this by using multiple blogging jobs that filter the bookmarks and assign the correct category. Also, I'm not too sure what the other blogging engines would do if they met a category that was not in their system. Mine creates a new category on the fly, others should ignore the category but this might not be the case. Worst case is that they would reject the post.

Back to point #1, I actually use categories to control access to the post. I have a set of normal categories, i.e. film, and a set of special categories, i.e. -public. Without one of the special categories, the post is considered to be in draft and will only appear on the main sub-domain. I can code around this limitation/feature by using the APIs publish flag. I'm having to code around a few blogging clients as it is ;-)

Thanks for listening,
Mark.
