Behavioural Equivalences for Dynamic Web Data

We study behavioural equivalences for dynamic web data in Xd#, a model for reasoning about behaviour found in (for example) dynamic web page programming, applet interaction, and web-service orchestration. Xd# is based on an idealised model of semistructured data, and an extension of the #-calculus with locations and operations for interacting with data. The equivalences are nonstandard due to the integration of data and processes, and the presence of locations.
