geneven,

whilst what you are entering now is unstructured, it contains enough information to be loosely tied together and an additional tagging interface will emerge as its fully constructed later.

I store all the information currently available to a user of system and am working on tying together your sessions into streams (grouping pages saved near to each other in time gives a really nice set of documents)

(the visualisation looks really neat so far)

The next step is full grouping and management but for my current thinking that requires more screen estate and a database to be done effectively.

I prefer to walk before I run
