Standards for Technology in Automotive Retail (STAR)
The STAR organization has defined standard data structures to facilitate integration between manufacturer and dealer business systems to enhance customer service and increase dealer productivity in the automotive industry.

STAR currently supports a number of methods for implementing different aspects of the standard.  As an example,

• Transport: STAR supports ebXML and Web Services.
• Authentication, Authorization & Privacy: STAR supports digital certificates, user ID & password, message level encryption, SAML Assertions, etc.
• Business Object Documents (BODs): STAR generally defines each field although each adopter could interpret them differently.  Also XML documents or flat files are allowed.

The PSP development team aligns its efforts with work done by the STAR organization. By developing a set of specifications that are STAR compliant, the PSP development group ensures that the PSP Standard is consistent with the work already being done by automotive divisions of companies that have business operations in other industries such as Powersports, Marine, Outdoor Power, RV and others.
