August: A Distributed Calendar Program
August is a calendar program written
in Java. It can be used as a single-user
calendar program or a distributed calendar program for a group of users.
In August, each user has a calendar and can specify policy. Policy determines
who is allowed to view which part of the user's calendar and who is allowed to
add an activity of a certain kind at a certain time.
Each August user declares different roles (or groups), e.g., friends, family
members, colleagues, etc., and defines the members of these roles. Users may
use delegation in defining role members. For example a user may specify that
"my family members' friends are also friends". This adds many users to a role,
using a single policy statement.
U-STOR-IT is a web-based file
sharing system. A user connects to U-STOR-IT using a browser. User
authentication is done using client-side certificates, generated by
the U-STOR-IT Certification Authority site. Users control access to
their lockers and files by specifying policy statements, which may refer
to other users' group-definition statements.
U-STOR-IT also provides collaboration tools such as basic version
control, per-file bulletin board, and in-system messaging.
