  1. 6.3 Unified Data Standards: A Challenging Task • The HTML/HTTP combination data format and exchange protocol is the foundation pillar of the World Wide Web. • Evolution of the Web (Fig. 6.12) 6.3 Unfied Data Standards

  2. Many standardization efforts have been trying to define a unified data representation and protocol for IoT. • Before the IoT, the Internet was actually an Internet of documents or of multimedia documents. The two pillars of the Internet including HTML/HTTP turned the Internet into the WWW. • By the same token, we need to turn the IoT into the WoT to make sense of everything. • What will it take to make this to happen? • Do we need a new HTML/HTTP-like standard for MTC and WoT? • The browser is intended for humans, so do we need a new browser for machines to make sense of the ocean of machine-generated data? • Today, most new protocols are built on top of XML. • HTML5, SMIL • Mango is an open-source software system for M2M application. It enables users to access and control electronic sensors, devices, and machines over multiple protocols simulateneously. • The Resource Description Framework (RDF) is a family of W3C specifications originally designed as a metadata model. 6.3 Unfied Data Standards

  3. SOAP and RESTful protocol frameworks are extension on top of HTTP for web services. SOAP and REST frameworks can be used to provide data exchange protocols for IoT applications. • There are two important enabling technologies electronic data interchange (EDI) and XML. EDI describes the rigorously standardized format of electronic documents. • XML is a more recent invention for exchanging information between computer systems. XML is a markup language used to create smart data and documents for applications 6.3 Unfied Data Standards

  4. ebXMLincooporates as part of its design solution some borrowed ideas from both EDI and XML. It offers businesses the opportunity to build an interoperable e-commerce infrastructure. • ebXML (e-business XML) specifies the business rules for how two different system talk to each other. 6.3 Unfied Data Standards

  5. 6.3.1 Unified Identification of Objects • One of the key issues of unified data format for IoT is the unique identification of objects. • However, when the WoT applications prevail in the future, globally unique identification of objects becomes a serious issue. • Object identification can essentially encompass the naming, addressing, or both of an asset or device. 6.3 Unfied Data Standards
