Bozzon, Alessandro, Comai, Sara, Fraternali, Piero and Carughi, Giovanni Toffetti (2006): Capturing RIA concepts in a web modeling language. In: Proceedings of the 2006 International Conference on the World Wide Web 2006. pp. 907-908. Available online

“This work addresses conceptual modeling and automatic code generation for Rich Internet Applications, a variant of Web-based systems bridging the gap between desktop and Web interfaces. The approach we propose is a first step towards a full integration of RIA paradigms into the Web development process, enabling the specification of complex Web solutions mixing HTTP+HTML and Rich Internet Applications, using a single modeling language and tool.”

Brambilla, Marco, Ceri, Stefano, Comai, Sara and Tziviskou, Christina (2005): Exception handling in workflow-driven Web applications. In: Proceedings of the 2005 International Conference on the World Wide Web 2005. pp. 170-179. Available online

“As the Web becomes a platform for implementing B2B applications, the need arises of Web conceptual models for describing Web oriented workflow applications implementing business processes. In this context, new problems about process correctness arise, due to the loose control of Web applications upon the behavior of their Web clients. Indeed, incoherent user's behavior can lead to inconsistent processes. This paper presents a high level approach to the management of exceptions that occur during the execution of processes on the Web. We present a classification of exceptions that can be raised inside workflow-driven Web applications, and recovery policies to retrieve coherent status and data after an exception. We devise these concepts at high level and then we exploit them using a Web modeling language (WebML) that in turn provides development facilities like automatic code generation, validation of hypertext models, and so on. An industrial implementation experience is briefly presented too.”

Comai, Sara, Damiani, Ernesto and Fraternali, Piero (2001): Computing graphical queries over XML data. In ACM Transactions on Information Systems, 19 (4) pp. 371-430

“The rapid evolution of XML from a mere data exchange format to a universal syntax for encoding domain-specific information raises the need for new query languages specifically conceived to address the characteristics of XML. Such languages should be able not only to extract information from XML documents, but also to apply powerful transformation and restructuring operators, based on a well-defined semantics. Moreover, XML queries should be natural to write and understand, as nontechnical persons also are expected to access the large XML information bases supporting their businesses. This article describes XML-GL, a graphical query language for XML data. XML-GL's uniqueness is in the definition of a graph-based syntax to express a wide variety of XML queries, ranging from simple selections to expressive data transformations involving grouping, aggregation, and arithmetic calculations. XML-GL has an operational semantics based on the notion of graph matching, which serves as a guideline both for the implementation of native processors, and for the adoption of XML-GL as a front-end to any of the XML query languages that are presently under discussion as the standard paradigm for querying XML data.”
