Abstract: Suppose that we have a query q under schema S and then S is updated. Then we have to update q according to the update of S, since otherwise q no longer reports correct answer. However, updating q manually is often a difficult and time-consuming task since users do not fully understand the schema definition or are not aware of the details of schema update. In this paper, we consider transforming queries automatically according to schema update. We focus on Shape Expression (ShEx) and Property Path as schema and query language, respectively, and we take a structural approach to transform Property Path query. For a Property Path query q and a schema update op to an ShEx schema S, our algorithm checks how op affects the structure of q under S, and transforms q according to the result.
