Liberty Alliance Profile Service Specification

The Liberty Alliance defines a global framework for identity management. This framework relies extensively on XML technologies (format and services specifications). The Liberty Alliance provides in particular a certain number of schema (expressed as xml schema) to describe person’s information. 

More precisely, these schemas include: 

1. Personal Profile
   The ID-SIS Personal Profile specification defines a Liberty Identity Service that supports person’s information regarding the Principal itself, be it in a private or work capacity. It is not intended to be a fully generic contact book and may not address all requirements of e-commerce applications. It is intended to be the least common denominator for holding.

2. Employee Profile
   ID-SIS-EP provides basic employee information. It is a Liberty Identity Service that supports person’s information regarding the Principal when in her job function.

3. Contact Book
   The Liberty ID-SIS Contact Book (ID-SIS-CB) is a Liberty Identity Service that allows a Principal to manage contacts for private and business acquaintances, friends, family members, and even for herself. ID-SIS-CB supports communications applications, acting as Principal’s phone or address book, allowing her quickly and easily to locate the information needed to contact people and businesses. Many other applications may also benefit, e.g., an e-commerce application may enable the Principal to ship to any address in the Principal’s Contact Book.

4. Geo-location
   The Liberty ID-SIS Geo-location (ID-SIS-GL) defines a web service. It offers geo-location information regarding a Principal. The geo-location information includes the position of a Principal, speed and direction related information, and information related to the quality of the position information.

5. Presence
   The core meaning of "presence" refers to a Principal’s availability for communications over a network. Examples include availability to talk over a traditional or mobile telephony network, chat over an instant messaging (IM) network, and participate in a video conference. In this core sense, presence is a boolean, "on/off" indicator of network availability. Over time, this core notion of presence has been extended to include other information about the Principal that changes quickly or that affects the Principal’s interest in or ability to engage in communications. Examples of such "extended presence" include the Principal’s proximity to or interaction with a user agent (e.g., "away" or "do not disturb"), activity (e.g., "driving"), mood (e.g., "grumpy"), and date/time ranges for availability.
