Abstract. Provenance is information recording the source, derivation, or his-
tory of some information. Provenance tracking has been studied in a variety of
settings; however, although many design points have been explored, the mathe-
matical or semantic foundations of data provenance have received comparatively
little attention. In this paper, we argue that dependency analysis techniques famil-
iar from program analysis and program slicing provide a formal foundation for
forms of provenance that are intended to show how (part of) the output of a query
depends on (parts of) its input. We introduce a semantic characterization of such
dependency provenance, show that this form of provenance is not computable,
and provide dynamic and static approximation techniques.
