Notas do Editor
- A graduate of Oxford University, Tim Berners-Lee invented the World Wide Web, an internet-based hypermedia initiative for global information sharing while at CERN, the European Particle Physics Laboratory, in 1989. He wrote the first web client and server in 1990. His specifications of URIs, HTTP and HTML were refined as Web technology spread.He is the Director of the World Wide Web Consortium (W3C), a Web standards organization founded in 1994 which develops interoperable technologies (specifications, guidelines, software, and tools) to lead the Web to its full potential. He is a founding Director of the Web Science Trust (WST) launched in 2009 to promote research and education in Web Science, the multidisciplinary study of humanity connected by technology. Tim Berners-Lee was born in London, England, on 8 June 1955, the son of Conway Berners-Lee and Mary Lee Woods.[8] He attended Sheen Mount primary school, and then went on to Emanuel School in London, from 1969 to 1973. He studied at The Queen's College, Oxford, from 1973 to 1976, where he received a first-class degree in Physics.The World Wide Web, abbreviated as WWW and commonly known as the Web, is a system of interlinked hypertext documents accessed via the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia and navigate between them by using hyperlinks. Using concepts from earlier hypertext systems, Sir Tim Berners Lee, wrote a proposal in March 1989 for what would eventually become the World Wide Web.[1] He was later joined by Belgian computer scientist Robert Cailliau. In 1990, they proposed using "HyperText [...] to link and access information of various kinds as a web of nodes in which the user can browse at will",[2] and released that web in December.Tim Berners-Lee and Robert Cailliau, published a more formal proposal (on November 12, 1990) to build a "Hypertext project" called "WorldWideWeb" (one word, also "W3") as a "web" of "hypertext documents" to be viewed by "browsers", using a client–server architecture.
- Web services are typically application programming interfaces (API) or web APIs that are accessed via Hypertext Transfer Protocol
- BrowsersMost modern browsers allow you to browse Atom based feeds. Simply point your browser at one of the OData producers.OData ExplorerA Silverlight application that can browse OData Services. It is available as part of the OData SDK Code Samples, and is available online at Silverlight.net/ODataExplorer.Excel 2010PowerPivot for Excel 2010 is a plugin to Excel 2010 that has OData support built-in.LINQPadLINQPad is a tool for building OData queries interactively.SesameA preview version of FabriceMarguerie'sOData Browser.Client LibrariesClient libraries are programming libraries that make it easy to consume OData services.
