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, strong relations between theory and
practice are not always evident. Few conceptual instruments for
analysis and reasoning or software verification techniques and tools
have been so far presented by the respective companies. Without the
ability to show a great practical impact, mathematical rigor risks
to become pointless. 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:
ws-fmtools@cs.unibo.it
Submissions must include:
* Name of the tool
* Name(s) of the author(s)
* Name(s) of the person(s) presenting the demo at the workshop
* A short abstract presenting the tool and the underpinning theory. It should describe the way in which the theory benefits the implementation.
* A link to a web site presenting the project.
Submissions deadline: 3 August 2005
DEMO MODALITIES
The demos presentation will be held as a special session of WS-FM
2005. Each presentation will take about 25 minutes plus 10 for the
discussion.
