The document discusses Web Services and how they can be applied to devices using the Device Profile for Web Services. It describes how WS specifications can be scaled down to work on limited resource devices. The Device Profile defines a lightweight subset of WS specs for device communication and includes security, discovery, and other protocols. Microsoft's implementations in Windows Vista and .NET support these standards for printer, scanner, and other device integration.

2. What Is Web Services? PCs Servers Services TCP/IP WS Protocols Software talking to Software

3. What Is Web Services on devices? PCs Devices Servers Services TCP/IP WS Protocols Device Profile for Web Services Software talking to Software on devices

4. Web Services Scales “ Scales Down” to devices “ Scales In” on a machine “ Scales Up” on large systems “ Scales Away” spans organizations & geographies “ Scales Out” by adding machines

5. Why Web Services Devices need to interoperate! Building devices that work with 3 rd party applications increases value to customer Build devices that work with Internet services could add revenue streams HTML and browsers are limited Browsers can’t automatically collect data Browsers can’t automatically control devices Custom protocols are costly

6. Quality WS protocols will be long-lived They’re general purpose and are being adopted by many large companies Enterprise-ready framework Already proven in the enterprise Allow your devices to move seamlessly between So-Ho and enterprise environments Multi-party reviews and interop events for each spec

7. Security Integrity, Confidentiality Channel-Based (TLS) Message-Based (WS-Security) Secure content Scenario – print job content securely over the wire, allowing devices to be implemented at secure sites Secure communications Scenario – secure check printing

11. Device Profile for Web Services Built on the foundation of industry standard Web Services Extensible Markup Language (XML) Simple Object Access Protocol (SOAP) WS-Discovery, WS-Addressing… (WS-*) Web Service Definition Language (WSDL) Message Transmission Optimization Mechanism (MTOM) Developed using the WS workshop process Co-Authors include Intel, Canon, Ricoh, and Lexmark.
