Topic on Manual talk:Tags/Flow

I saw the manual:tag, but still unknow how to add tag to wiki article,anyone can help me ?

Niether do I. But these are change tags, you can add them to changes.

I thought "tags" are so fundamental feature in all CMS (and many other stuff), but I don't know why MediaWiki don't support it, this is so important feature to manage information. Enumerative classification (traditional hierarchical tree structure) and Faceted classification (tag, or hashtag) are 2 major way in information classification and organization, is there any way this is still not a core feature in MediaWiki?

Maybe there was no demand? Wikis usually "tag" pages using the other system (ie. categories) or templates.

Yes you are right, thanks for reminding me, MediaWiki categories are equivalence to tags in other CMS. But "it seems" unless using extension (like Extension:Multi-Category Search), there is no "native" way to do a searching with one category, or multiple category, maybe I'm wrong?

Right, no native way AFAIK. But this is where extensions arise.

Can be used for tags - but so much more.

Semantic Mediawiki (SMW) is a free, open-source ex­ten­sion to MediaWiki that lets you store and query data with­in the wiki's pages.

I haven't found a built-in way of using tags, but I have used a workaround by placing keywords/tags separated by commas between HTML Comment tags in my articles.
