abstract:
We present our approach to the denotation and representation
of hierarchical graphs: a suitable algebra of hierarchical graphs and two
domains of interpretations. Each domain of interpretation focuses on
a particular perspective of the graph hierarchy: the top view (nested
boxes) is based on a notion of embedded graphs while the side view (tree
hierarchy) is based on gs-graphs. Our algebra can be understood as a
high-level language for describing such graphical models, which are well
suited for defining graphical representations of service-oriented systems
where nesting (e.g. sessions, transactions, locations) and linking (e.g.
shared channels, resources, names) are key aspects.
