Tagging and categorising content is a key concept of any Web 2.0 application. People are asked to make sense of the endless amount of content through “crowd-sourcing”. Here at ARIS Community, we also rely on your support in sorting the content. We use categories and tags for this purpose, but what is the difference?
Well, a tag is something everyone registered at ARIS Community can assign to any post. You are free to choose as many tags as you want. If you read an article, just use the words as tags, which come first to your mind. You can only assign tags if you are currently logged in to ARIS Community. Let’s take a look at the head of a post:
I have added 3 red numbers to the screenshot. The part marked with a red “1” shows you all tags assigned to this post. If you click on a tag, you will get to a page listing all posts with this tag. The part marked with a red “2” shows you the tags you assigned to this post. You can remove a previously assigned tag by clicking on it. Finally, the edit form marked with a red “3” allows you to add a new tag to a post.
Tags can be used to discover new content. For example, in the right sidebar of the page, you will see a list of tags used most often. You can also get a list of all tags used so far, but be aware that it is a rather long list ;-)
In sum, tagging is done by everyone! In contrast, assigning a post to a category is only done by the author of the post. Furthermore, an author can’t create new categories, but has to choose among those already available. Currently, there are only 12 categories and the number won’t grow very much.
I hope this clarifies the difference between categories and tags and why your post does not have any tags if you just published it.
