Given a choice, everyone would like to deal with someone of good reputation. However, getting information about a person's reputation might not be easy. If easily shared, the profiles maintained by individual personal assistants could help users to determine an individual's system-wide reputation. Roles People often play more than one role in society. Users' business cards can be structured into different aspects that capture information about these roles.
Aspects help refine the knowledge represented in a business card.
Users may specify preferences for each of their roles. For example, a scientist in a small company may also have the role of building liaison. However, the user prefers to receive building complaints only late in the afternoon and only when in the office, and can specify these preferences accordingly. Each aspect specifies which role it corresponds to and how to reach the user regarding that role. A user does not have to specify aspects as a default top aspect is defined for every card.
