[Web4lib] Tagging @ Sub-Document Level(s)?

[McKiernan, Gerard [LIB]]

Colleagues/
 
Are you aware of any current applications/technologies that allows one to Tag a document at the **Paragraph** (or Chapter) level? (and Not Only At The Document Level)?
 
I am also interested Tag Cloud technologies that allows for the visualization of Tags associated with selected 
Paragraphs (or Book Chapters or Other Formal Parts Of A Work).
 
Thanks!
