Identity Service Interface Specification (ID_SIS)
The Liberty Identity Service Interface Specification (ID-SIS) used the ID-WSF and ID-FF specifications to provide networked identity services, such as contacts, presence detection, or wallet services that depend on networked identity. The SIS contained two specifications:
Personal Profile (ID-SIS-PP): This is a Web service. It offers basic profile information regarding a Principal, including name, legal identity, and a minimal set of contact information such as legal domicile, home, and work addresses. The profile may also contain phone numbers, emails and other online contact information. Some basic demographics and presentation information and employment and public key details may also be included. An extension mechanism allows other arbitrary data to be included. An ID-SIS-PP service only stores information regarding the Principal him- or her-self and does not target contact management or e-commerce applications.
Employee Profile (ID-SIS-EP): This is a Web service. It offers profile information regarding an employee. ID-SIS-EP provides basic employee information.
