  Web applications frequently leverage resources made available by remote web
servers. As resources are created, updated, deleted, or moved, these
applications face challenges to remain in lockstep with the server's change
dynamics. Several approaches exist to help meet this challenge for use cases
where "good enough" synchronization is acceptable. But when strict resource
coverage or low synchronization latency is required, commonly accepted
Web-based solutions remain elusive. This paper details characteristics of an
approach that aims at decreasing synchronization latency while maintaining
desired levels of accuracy. The approach builds on pushing change notifications
and pulling changed resources and it is explored with an experiment based on a
DBpedia Live instance.
