The Web-Enabled Navy: :  The Web-Enabled Navy: Made possible through XML Topics :  Topics What is the Vision for the Web-Enabled Navy? How do we get there? How is XML different from HTML? Web Enabled Navy (WEN) :  Web Enabled Navy (WEN) Operational and business processes are conducted worldwide via interconnected and interoperable web-based IT systems. TFW Mission: “To provide integrated and transformational information exchange for both the ashore and afloat navy to take full advantage of Navy’s IT21 and NMCI infrastructure investments.” Slide4:  Current State of the World Wide Web Numerous Web Sites Increasing Every Day Slide5:  Portals vs. Vortals Portal -- A Web site or service that offers a broad array of resources and services, such as e-mail, forums, search engines, and on-line shopping malls. The first Web portals were online services, such as AOL, that provided access to the Web, but by now most of the traditional search engines have transformed themselves into Web portals to attract and keep a larger audience. Vortal -- Vertical Industry Portal is a portal Web site that provides information and resources for a particular industry. Vortals are the Internet's way of catering to consumers' focused-environment preferences. Vortals typically provide news, research and statistics, discussions, newsletters, online tools, and many other services that educate users about a specific industry. As the Web becomes a standard tool for business, vortals will join and maybe replace general portal sites like AOL and Yahoo! as common gateways to the Internet.

Extensible Markup Language - XML:  Extensible Markup Language - XML Method for Putting Structured Data into Text File Set of rules, guidelines, conventions for structured data Cross-platform, software and hardware independent standard for transmitting information Looks Similar to HTML, But….. XML Describes Information; HTML Displays Information Text based, but not Meant to be read (machine readable) Text files allow ease of debugging Way to structure, store, and send information Conglomeration of Technologies XML Specification, stylesheets, schemas, etc. XML vs HTML:  XML vs HTML Both are a subset of SGML -Standard General Markup Language. SGML is too complex. It is used for describing different document types, from ancient Irish manuscripts to musical notation. HTML doesn’t enforce a strict structure, and is not implemented by all browsers the same. Can’t handle data rich pages well. HTML is limited to displaying documents and information with some hypertext and multimedia. XML describes information while HTML displays it. XML is a “metalanguage” - a language for describing other other languages. Can design your own markup language (e.g. MetocML). Slide18:  Rules for XML Coding: Begin with the XML Declaration: <?xml version=“1.0” standalone=“yes” encoding=“iso-8859-1”?> All tags must have an end tag: <greeting>Hello, world!</greeting> All tags must be in matched case: <title> Document title </title> or <LI> List item </LI> All tags must be properly nested: you <b>must do it <i> this </i> way</b>, not <b><i>this</b> </i> way. WEN Benefits:  WEN Benefits More ubiquitous access to information services Afloat/Ashore Via web browsers Improved interoperability Extensive use of XML Separation of data from presentation layer enables support for multiple display devices Improved quality of information Establishment of authoritative, central databases supporting similar services across multiple locations Ability to aggregate data from multiple sources Reduced Total Costs Software support & hardware costs reduced Configuration management simplified
