Scoping strategies for distributed aspects

Dynamic deployment of aspects brings greater flexibility and reuse potential, but requires a proper means for scoping aspects. Scoping issues are particularly crucial in a distributed context: adequate treatment of distributed scoping is necessary to enable the propagation of aspect instances across host boundaries and to avoid inconsistencies due to unintentional spreading of data and computations in a distributed system. We motivate the need for expressive scoping of dynamically-deployed distributed aspects by an analysis of the deficiencies of current approaches for distributed aspects. Extending recent work on scoping strategies for non-distributed aspects, we then introduce a set of high-level strategies for specifying locality of aspect propagation and activation, and illustrate the corresponding gain in expressiveness. We present the operational semantics of our proposal using Scheme interpreters, first introducing a model of distributed aspects that covers the range of curr...
