Abstract

We identify the mechanisms needed to construct archivable webs ofdistributed asynchronous collaborations and experiments. The distinguishingfeature of our approach is that the component tools, software, data, andeven participants are distributed over a worldwide network. We perform arequirements analysis of an infrastructure that supports such applications,and present the Caltech Infospheres Infrastructure as a prototype thatsatisfies the requirements identified. In describing this prototype, wehighlight the useful mechanisms provided, present an algorithm for using theInfospheres Infrastructure to perform asynchronous global snapshots forarchiving, and suggest future areas of exploration.
