International Workshop on
Web Information Systems Modeling (WISM 2007)

Theme of the Workshop

Modern Web Information Systems need to fulfil a large number of requirements. As a consequence the design of these systems is not a trivial process. In order to facilitate WIS modeling, WIS design methodologies propose models in order to describe the specific aspects of these systems.
Recent advances in networking technologies made possible the WIS access using different devices (e.g., PDA, Smart Phone, PC, Black Berry, etc.). In addition to the device heterogeneity there is also a heterogeneous audience (e.g., different backgrounds, different goals, etc.) that wants to access the same system. In order to improve the user experience, these systems often need to personalize the content and its presentation based on the current user needs (e.g., user's browsing platform or user preferences).
Another aspect that can influence the behaviour of a WIS is the context of use (e.g., the geographical position, the temporal information, the weather conditions, etc.). Systems that are able to exploit this kind of information will further improve the application usefulness for its users. Such information is possibly made available by Web services that need to be seamlessly integrated in WIS.
As the Web data is very diverse, WIS are seeking efficient and flexible approaches to provide integrated views over heterogeneous data sources. These data sources are usually autonomous (maintained by different organizations), overlapping, frequently changing, and distributed, all these characteristics making the data integration on the Web a very challenging research topic.
The increased use of rich-clients applications (e.g., AJAX, OpenLaszlo) poses new demands to WIS design. The design of these applications needs to go beyond the server roundtrip paradigm by considering the new functionality added to clients, an intelligent data-push communication with the server, interactive-rich graphical interfaces, etc.
Semantic Web technologies (e.g., RDF(S), OWL, etc.) can help in the representation of the different WIS design models aiming for an improved interoperability. One example of such a model is the user profile which is often described using a CC/PP vocabulary. Semantic Web representation languages prove to be useful also for describing the semantics of data and the semantics of interfaces in order to facilitate the integration of heterogeneous databases and Web services, respectively. The inference mechanisms of the Semantic Web (captured in the semantics of the representation language or in rule-based languages like RuleML and SWRL) can be used for deriving new information or building intelligent services on the Web.
Over the last few years, Web services have offered new opportunities to deploy WIS. Web services are independent from specific platforms and computing paradigms and have the capacity to form composed processes, referred to as composite Web services. Web services composition fulfills user requests that require the participation of several component Web services. Several composition languages are now available (e.g., BPEL, WSFL). A research venue that is worth pursuing is the modelling of these composite Web services.

Goal of the Workshop

The aim of the workshop is to provide a platform for bringing together researchers, practitioners, designers, and users of WIS and discuss how specific issues in model-driven design of WIS can increase the ubiquity of these systems. Specifically, we will discuss how the influence of Semantic Web technology can help to improve the ubiquity of WIS. Thus, the workshop should enable a fruitful exchange of ideas in the state-of-the-art of WIS modeling.

Topics of Interest

The workshop topics include but are not limited to:

• WIS Ubiquity

Paper Submission

Prospective workshop participants are invited to submit a paper related to one (or more) of the workshop topics. Papers should not exceed 5000 words in length and should be formatted as close as possible to the Springer LNCS style http://www.springer.de/comp/lncs/authors.html. They need to be original and not submitted or accepted for publication in any other workshop, conference, or journal. The organizers will oversee a peer-review process for the submitted papers. Papers should be submitted to wism2007@win.tue.nl in PDF format.

Publication

Workshop proceedings will be published in the official CAiSE workshop proceedings with an ISBN number. Authors of selected papers will be invited to submit extended versions for publication in prestigious international journals.
