The animals are divided into:(a) belonging to the emperor,(b) embalmed, (c) tame, (d) sucking pigs, (e) sirens, (f) fabulous, (g) stray dogs, (h) included in the present classification,(i) frenzied, (j) innumerable, (k) drawn with a very fine camelhair brush, (l) et cetera, (m) having just broken the water pitcher, (n) that from along way off look like flies.

  5. Facets simplify hierarchies

  6. Metadata used in search

  7. Universal facets and partial facets

  8. Limits on facet displays Most facets are hidden!

  9. Modern websites rely on metadata

  10. Who decides what metadata is needed?

  11. Where does metadata come from?

  12. What does it cost to create metadata? Consider complexity of facet and ambiguity of content to estimate time per value. Machine-filled fields have costs too. Is this field worth the cost? Estimated cost of tagging one item. This can be reduced with automation, but cannot be eliminated. Inspired by: Ray Luoma, BAU Solutions

  13. Can we get machines to make metadata for us?

  14. How much metadata do I need?

  15. Can we get machines to make taxonomies for us?

  16. Can we get users to make taxonomies for us?

  17. Where else might we find taxonomies?

  18. Um, is someone managing all this?

  19. How do I start?
