WS-FM 2005 Call For Papers

======================================================================
                     2nd International Workshop on
                    Web Services and Formal Methods
                             (WS-FM 2005)

                1-3 September 2005, Versailles, France

                      http://cs.unibo.it/WS-FM05

                        Co-located with EPEW'05
             2nd European Performance Evaluation Workshop 

======================================================================

SCOPE

 Web Services technology aims at providing standard mechanisms for
 describing the interface and the services available on the web, as well
 as protocols for locating such services and invoking them (e.g. WSDL,
 UDDI, SOAP). Innovations are moving towards two main directions:
 The first one tends to the definition of new standards
 that support the specification of complex services out of
 simpler ones (the so called Web Service orchestration and choreography).
 Several proposals have been already set up: BPML, XLANG and
 BizTalk, WSFL, WS-BPEL, WS-CDL, etc...
 The second approach consists of the design of new (meta-)Web Services to
 be exploited at run-time by other Web Services: e.g. managing
 the cooperation of Web Services or acting as dynamic registry services.

 Formal methods, which privide formal machinery for representing and
 analysing the behavior of communicating concurrent/distributed systems,
 may potentially play a fundamental role in the development of such
 innovations. First of all they may help in understanding the basic
 mechanisms (in terms of semantics) which characterize different
 orchestration and choreography languages and to focus on the essence 
 of new features that are needed. Secondly they may provide a formal 
 basis for reasoning about Web Service semantics (behaviour and 
 equivalence): e.g. for realizing registry services where retrieval 
 is based on the meaning of a service and not just a Web Service name. 
 Thirdly also studies on formal coordination paradigms can be exploited 
 for developing mechanisms for complex run-time Web Service coordination. 
 Finally, given the importance of critical application areas for 
 Web Services like E-commerce, the development of the Web Service 
 technology can certainly take advantage from formal analisys of 
 security properties and performance in concurrency theory.

 The aim of the workshop is to bring together researchers working
 on Web Services and Formal Methods in order to activate a fruitful
 collaboration in this direction of research. This, potentially, could
 also have a great impact on the current standardization phase of Web
 Service technologies.

LIST OF TOPICS

 The topics of interest include, but are not limited to:

   - Protocols and standards for WS (SOAP, WSDL, UDDI, etc... )
   - Languages and descripion methodologies for
     Coreography/Orchestration/Workflow
     (BPML, XLANG and BizTalk, WSFL, WS-BPEL, WS-CDL, YAWL, etc... )
   - Coordination techniques for WS
     (transactions, agreement, coordination services, etc...)
   - Semantics-based dynamic WS discovery services
     (based on Semantic Web/Ontology techniques or other semantic theories)
   - Security, Performance Evaluation and Quality of Service of WS
   - Semi-structured data and XML related technologies
   - Comparisons with different related technologies/approaches

 Submissions must be original and should not have been published 
 previously or be under consideration for publication while being

WS-FM 2005 Call For Tools

[Mario Bravetti]

WS-FM 2005 TOOLS SESSION

Tools session in 2nd International Workshop on Web Services and
Formal Methods

Versailles, 2-3 September 2005, France

http://www.cs.unibo.it/WS-FM05

Web services technology is a widespread accepted instantiation of
Service Oriented Computing which facilitates integration of newly
built and legacy applications both within and across organizational
boundaries avoiding difficulties due to different platform,
heterogeneous programming languages, security firewall, etc... The
idea behind the WS approach is allowing independently developed
applications to be exposed as services and interconnected exploiting
the already set up Web infrastructure with relative standards (HTTP,
XML, SOAP and WSDL). The technologies related to developing basic
services and interconnecting them on a point-to point basis can be
considered well established but B2B processing requires managing
more complex interactions involving a large number of participants
and none of the above standards are able to meet this need. For this
reason the so-called Web services Composition Languages like XLANG,
WSFL, BPML, WS-BPEL and WS-CDL are taking place. These languages are
claimed to be based on formal models (pi-calculus variants, Petri
Nets) to allow rigorous mathematical reasoning. However, despite all
this hype, no interesting relations with formal methods have been so
far emphasized and no conceptual instruments for analysis and
reasoning or software verification techniques and tools have been so
far presented by the respective companies. Any mathematical rigor
becomes pointless without the ability to show these kind of results.
In this sense contracts conformance verification between different
services and static analysis of behavioral properties becomes one of
the most promising research directions.

The aim of the tools session is presenting working prototypes
designed exploiting the experience derived from concurrency theory
(and formal methods in general) in order to strengthen the
collaboration with industry and resulting in a strong impact on the
standardization phase of composition languages and of web services
technologies in general.

LIST OF TOPICS

The topics of interest include, but are not limited to:

    * Orchestration engines for Web services
    * Frameworks for recovery mechanisms in Web services composition
    * Static analyzers and verificators of behavioral properties
    * Contracts conformance checkers
    * Frameworks for securing Web services

SUBMISSION MODALITIES

To submit please send the information below to:

    * Name(s) of the author(s)
    * Name(s) of the person(s) presenting the demo at the workshop

Submissions deadline: 3  August 2005
