We just launched an update to the MSDN Library. As part of the release, a new tags control will show up on library documentation with the Community Content feature (currently 1.5 million pages across 7 languages). There is a page level tagging control right below the topic content and one added to each Community Content block. You will see this available on the following documentation:
In case your new to tagging, here is a brief intro:
What are Tags and what is "Tagging"?
Tags are essentially keywords or labels added to an web page that are intended to describe the contents of the page so that it can be more easily retrieved and put in a structure. Tags are really just a special kind of attribute that help people understand what a given piece of content is about. Generally, when we talk about "tagging" we mean the process of applying tags to content.
For MSDN, tagging helps surface content that might not be easily discovered in the long tail of the Library. This is especially the case with newly added Community content. This implementation is unique in that the tags are wikified, meaning they can be added and/or removed by any and all users in the community. This isn't social bookmarking tagging like on Tagspace or del.icio.us. Those sites are about keeping your bookmarks or internet favorites for you and then sharing them out. Tagging in the MSDN Library is about helping content be discovered. This will help make search more relevant in the long term. Check out this query -> C# code examples. How cool is that?
How it worksThere are two parts to using tagging on the site. The first is adding tags and the second is browsing the tags on the site:
Who can add tags?
Adding tags has the same requirements as the Community Content feature:
