Executive Summary

The amount of data that home users generate, store, and peruse has grown significantly in the past few years. Increasingly, organizing this huge amount of data - in order to make it easy to browse, query and access - is becoming challenging. Many recent proposals have emphasized the importance of data management in home networks and pro-posed mechanisms for managing replicas across devices to increase availability. Essentially, they capture the relation-ship "Is copy of" between files across devices. However, files can be semantically related. Users are often interested in finding data that has such semantic relationships; tracking these relationships helps users to effectively search based on content or human-understandable context, organize data and manage the limited storage while ensuring availability of information.
