This talk presents BPQL, a novel graphical query language for
querying Business Processes, implemented as a set of
cooperating
web services. BPQL is based on an intuitive model of business
processes, an abstraction of the
emerging BPEL (Business Process
Execution Language) standard. It allows users to query business
processes visually,
in a manner analogous to how such processes
are typically specified, and can be employed in a distributed
setting,
where process components may be provided by distinct
providers (peers).
The talk describes the query language as well as its underlying
formal model. Special emphasis is given to the following subjects:
(a) The analogy between the specification and querying of business
processes, and (b) the use of graph grammars to
represent
potentially infinite query results by a finite and concise
representation.
The current implementation, using Active XML and
Web services is briefly described.
