7. Concept vs Representation Oxford English Dictionary: –the fact of coming from some particular source or quarter; origin, derivation –the history or pedigree of a work of art manuscript, rare book, etc.; –concretely, a record of the passage of an item through its various owners. We are interested in a representation of provenance in computer systems Wouldn’t it be useful to have a term to denote the representation so that we can distinguish it from the concept? Provenance log, provenance trail, provenance records, provenance information, provenance trails

8. `Provenance’ Pearls Actor Provenance is this the provenance of an actor? Provenance history: is this history of history? Data provenance data: an element of the representation of the provenance of a data item? Provenance metadata: metadata of some metadata? Provenance of interactions: the description of interactions or what caused an interaction to occur? We do provenance: are we making history?

9. Conclusions Do we really need 124 different usages of the word provenance? Do we need inconsistent terminology? We need a glossary
