This module will examine the management of dynamic data, for a variety of distributed Web applications.
The course includes an introduction to standard tools for developing Web applications (REST/SOAP Web Services, XML/JSON, XSLT, BPEL), followed by an exploration of the problems that come from the dynamic nature of the data returned by Web services: wrapper construction, on-the-fly entity resolution, query evaluation using services with limited access patterns, workflow selection, verification/provenance of workflows.
We will also cover the dynamic integration into RDF knowledge bases (Linked Open Data) of the data exported by digital libraries using Web service APIs.

Prerequisites: Basics of the Web (HTTP, HTML, Web forms, XML), Basics of distributed and database systems.
