Is XDI a Web service?
XDI over SOAP is a Web service. However XDI can also be bound to HTTP for use in “RESTful” architectures, as well as to other transport protocols like SMTP/MIME. So strictly speaking XDI is a generalized service based on XML document exchange that can be implemented as a Web service. • What are the primary problems XDI is intended to solve? The general problem XDI is designed to address is interoperable, automated data interchange across distributed applications and trust domains. There are many specific examples of this problem: • Exchange, linking, and lifetime synchronization of electronic business cards, public keys, and other common identity attributes across distributed directories (commonly known as dynamic address books).* • Internet calendar sharing.* • Trusted search (searches that need to cross multiple private websites).* • Auto-configuration and intelligent data synchronization across multiple user devices (desktop, laptop, PDA, land phone, cell phone, etc.) • Automated we
