  Maintenance of multiple, distributed up-to-date copies of collections of
changing Web resources is important in many application contexts and is often
achieved using ad hoc or proprietary synchronization solutions. ResourceSync is
a resource synchronization framework that integrates with the Web architecture
and leverages XML sitemaps. We define a model for the ResourceSync framework as
a basis for understanding its properties. We then describe experiments in which
simulations of a variety of synchronization scenarios illustrate the effects of
model configuration on consistency, latency, and data transfer efficiency.
These results provide insight into which congurations are appropriate for
various application scenarios.
