V2_ uses its own list of keywords to describe items in the
archive. Many items will have several keywords attached
to them - for example "robotics", "electronic art", "antennas"...
These keywords are inter-related through hierarchical relations
("nanorobotics" is a narrower term of "robotics") and associative
relations ("cyberspace" triggers "virtual reality"). You
can browse this "tree" of keywords in order to get a thematic
view on V2_"s past activities.
