Abstract:
In this paper, we describe a novel context based storage system that use context to manage user data and make it available to him based on his situation. First, we examine several existing systems that use context with documents. Subsequently, a new storage system is presented that uses context to aid in the capture of and access to documents in mobile environment. We describe file browser and calendar applications that we have developed within our mobile computing infrastructure utilizing the features of context based storage. Novel features of our system include the access rights mechanism for data and support for group activity.

My Discussion:
A nice paper about a system that actually implements some ideas about context-based computing. The system described, CBS, is layered on top of a replicated distributed storage system that can work on wired computers and handhelds, making it appropriate for experiments in including contextual queues like location, time, and participants as metadata to store files.The actual applications do not get many page inches, but already hint at interesting crosslinks between data retrieval and occasions, like storing files with pointers to a meeting so that returning to the meeting becomes an entry portal to the files, that currently is not so easily done. I would like to see future work in this system.
