In this paper we consider provenance modelling in Adaptive Hypermedia Systems (AHS). We revisit adaptation and data provenance questions and bring up new and complementary aspects of adaptation and provenance, showing similar and supplementing characteristics. We also scrutinize the provenance importance and issues in Adaptive Hypermedia (AH). The aim of this paper is to extend the conventional AH classification questions with the notion of data lineage which essentially plays an important role in adaptation.
