As I said, we already have an internal taxonomy data structure that is used for our internal search engine, for categorizing our content, etc. It's crucial to keep this or things start going array when those tools are used. Each item in that taxonomy is used as a tag for marking items.
Now for dW Community, currently only the bloggers have their own "Category" tags, which are separate from the dW taxonomy. Because each blogger can create their own tags personally categorizing any of their posts, this can result in many variations of the same tag (same idea, different names), conflicts in the semantic usage of tags (different ideas, same name), and even ownership of those categories. Thus, you can think of these tags as having their own "individual scope" and exist in a different tag space than the full dW taxonomy.
Thus, there are now two scopes of tags: personal, and dW.
Next comes the issues with the big improvements coming in 2006. The plans for 2006 have been laid out but we haven't completely worked out the full tasks and implementation model. Hence, I haven't really described it yet... BUT it is coming and it will have a BIG impact in change! (we hope for the better in many ways)
So, with the new plan, we will start considering another scope of tags: those that span community-wide as a general folksonomy (see previous post).
In this scope, dW Community members can create a tag that exists in the public scope that anyone else can add, modify or even delete items from. This is where we start trusting our users to do what's best for themselves.
With any folksonomy there is potential for abuse and disaster when:
- picking a topic tag so big that it could contain a whole lot of other tags
- spamming into these tags
- malicious deletion of entries
Thus, a pure folksonomy can become total chaos if the facilities to backtrack, undo, alert, or generally administer those tags are not available.
Yet another way to do this is to introduce a new type of scoping. You still have a folksonomy, but you subdivide topics at a high level, and break them down into groups. Each group can have its own tags created by anyone in that group. It's folksonomy in limited scale and actually breaks the original idea some, but limits widespread chaos.
So thus the potential is that there may be a number of scopes: individual, group, dW, global
How do you refer to each of these scopes?
Globally-unique naming of each scope is usually enough.
