  Description     : a BPM/Workflow system

YAWL is a Java-based BPM/Workflow Management System. Based on a concise
and powerful modelling language, YAWL supports complex data, integration
with organizational resources and external applications, process
verification and process configuration.

YAWL offers the following distinctive features:
* YAWL offers comprehensive support for the control-flow patterns. It is
the most powerful process specification language for capturing
control-flow dependencies.
* The data perspective in YAWL is captured through the use of XML Schema,
XPath and XQuery.
* YAWL offers comprehensive support for the resource patterns. It is the
most powerful process specification language for capturing resourcing
* YAWL has a proper formal foundation. This makes its specifications
unambiguous and automated verification becomes possible (YAWL offers two
distinct approaches to verification, one based on Reset nets, the other
based on transition invariants through the WofYAWL editor plug-in).
* YAWL has been developed independent from any commercial interests. It
simply aims to be the most powerful language for process specification.
For its expressiveness, YAWL offers relatively few constructs (compare
this e.g. to BPMN!).
* YAWL offers unique support for exception handling, both those that were
and those that were not anticipated at design time.
* YAWL offers unique support for dynamic workflow through the Worklets
approach. Workflows can thus evolve over time to meet new and changing
* YAWL aims to be straightforward to deploy. It offers a number of
automatic installers and an intuitive graphical design environment.
* Through the BPMN2YAWL component, BPMN models can be mapped to the YAWL
environment for execution.
* The Declare component (released through provides unique
support for specifying workflows in terms of constraints. This approach
can be combined with the Worklet approach thus providing very powerful
flexibility support.
* YAWL's architecture is Service-oriented and hence one can replace
existing components with one's own or extend the environment with newly
developed components.
* The YAWL environments supports the automated generation of forms. This
is particularly useful for rapid prototyping purposes.
* Tasks in YAWL can be mapped to human participants, Web Services,
external applications or to Java classes.
* Through the C-YAWL approach a theory has been developed for the
configuration of YAWL models. For more information on process
configuration visit
* Simulation support is offered through a link with the ProM
( environment. Through this environment it is also
possible to conduct post-execution analysis of YAWL processes (e.g. in
order to identify bottlenecks).
