Annotating spiders with resource information

Abstract

The recently introduced notion of Modeling Spider Diagrams immerses Spider Diagrams in a modelling context. We enhance here their capabilities by including references to resources that are required to persist in some state or to perform some state transition. To this end, we introduce a notion of annotation, which can be expressed through a restriction of Conceptual Spider Diagrams (extended over domains), where domains are partially ordered and predicate edges have to be consistent with this ordering. The resulting notion of Annotated Modeling Spider Diagrams can then be used to express constraints on the usage of resources, so that conformance to a policy can be verified with respect to resource availability. We provide additional options for user-modelling choices via a natural equivalent representation in terms of (classical) Spider Diagrams, restricted on the domain of interest, and the use of colour for domain identification.
