Querying Structural and Behavioral Properties of Business Processesss processes as rewriting systems, an abstraction of the emerging BPEL (Business Process Execution Language) standard [7]. BPQL allows users to query business processes visually, in a manner very analogous to the language used to specify the processes. The goal of the present paper is to study the f

Analysis of Imperative XML Programsalyzing and optimizing imperative XML processing programs. In particular, we present a program analysis, based on a flow-sensitive type system, for detecting both redundant computations and redundant traversals in XML processing programs. The analysis handles declarative queries over XML data and im

Towards Practical Typechecking for Macro Tree Transducerser reports our first step toward an implementation of mtt typechecker that has a practical efficiency. Our approach is to represent an input type obtained from a backward inference as an alternating tree automaton, in a style similar to Tozawa’s XSLT0 typechecking. In this approach, typechecking red

https://doi.org/10.1007/978-1-349-07274-3nt. The algorithm is in LOGCFL and space consumption is strongly bounded, while the running time is linear in the size of the data tree. This algorithm immediately generalizes to the problem of matching the tree pattern against all subtrees of the data tree, preserving the mentioned efficiency properties.
