“Folkschemas”, nice word. I guess this is something I am trying to do with StYLiD (Structure Your own Linked Data).

The Linkexplorer organizes tagging by defining various relations between tags. This is similar to the approach used by BibSonomy. But there are different types of named relations (eg part-of, related-to, etc). This greatly helps to organize tags. However, I think tagging is quite uncontrolled and it will be difficult to have usable visualizations of relations between huge amounts of tags. Further, I am not sure if it should be called structured tagging. Some people use the term “structured tagging” to refer to structured metadata.
