Annotation and More Annotation: Some Problems Posed by (and to) Val Tannen Buneman, Peter Vansummeren, Stijn Annotation provenance semiring curated data Among the many research accomplishments of Val Tannen, his work on provenance and semirings is probably the most widely known. In this paper, we discuss questions that arise when applying this general framework to the setting of curated databases, and in particular the setting where we can have multiple annotations on the same data, as well as annotations on annotations.
