(If you are not able to use GitHub, please <a href="mailto:public-website-redesign@w3.org">email</a> <samp>public-website-redesign@w3.org</samp>, a <a href="https://lists.w3.org/Archives/Public/public-website-redesign/">publicly archived</a> mailing list.)</p><h2 id="invention">What does it mean that Sir Tim Berners-Lee invented the Web?</h2><p><a href="/People/Berners-Lee/">Sir Tim Berners-Lee</a> wrote a <a href="/History/1989/proposal.html">proposal</a> in 1989 for a system called the World Wide Web. He then wrote the first Web browser, server, and Web page. He wrote the first specifications for URLs, HTTP, and HTML.</p><h2 id="webinternet">What is the difference between the Web and the Internet?</h2><p>The Internet is a network of networks, defined by the TCP/IP standards, according to the <a href="https://en.wikipedia.org/wiki/Internet">definition in Wikipedia</a>: "<i>The Internet is a global system of interconnected computer networks that interchange data by packet switching using the standardized Internet Protocol Suite (TCP/IP).</i>"</p><p>The Web, on the other hand, is defined in W3C's <a href="/TR/webarch/">Architecture of the World Wide Web, Volume I</a> as follows: "<i>The World Wide Web (WWW, or simply Web) is an information space in which the items of interest, referred to as resources, are identified by global identifiers called Uniform Resource Identifiers (URI)</i>."</p><p>The Web is an information space. The first three specifications for Web technologies defined URLs, HTTP, and HTML.</p><p>It's such a common mistake to confuse the two that we made special t-shirts that Sir Tim Berners-Lee, inventor of the Web and Vinton Cerf, inventor of the Internet, wore during the <a href="/20/">W3C 20th anniversary event</a> of October 2014.</p><p><a href="https://www.w3.org/20/"><img src="https://www.w3.org/20/img/event/0O4A8746_large.jpg" alt="Tim Berners-Lee and Vint Cerf show one side of their T-shirts, saying who did not invent what"></a></p><h2 id="activity">What does W3C do?</h2><p>W3C's primary activity is to develop protocols and guidelines that ensure long-term growth for the Web. W3C's standards define key parts of what makes the World Wide Web work. Learn more about <a href="https://www.w3.org/mission/">W3C's mission</a>.</p><h2 id="governance">How is W3C organized?</h2><p>On January 2023, <a href="https://www.w3.org/news/2023/w3c-re-launched-as-a-public-interest-non-profit-organization/">W3C became its own legal entity</a>, moving to a <strong>public-interest non-profit organization</strong> after 28 years with an atypical organizational structure where legal and fiduciary roles were assumed by four historical host institutions across the planet: <a href="https://www.csail.mit.edu/"><abbr title="Massachusetts Institute of Technology">MIT</abbr></a> (USA), <a href="https://www.ercim.eu"><abbr title="European Research Consortium for Informatics and Mathematics">ERCIM</abbr></a> (France), <a href="https://www.keio.ac.jp/en/">Keio University</a> (Japan), and <a href="https://ev.buaa.edu.cn/">Beihang University</a> (China). Read more about our <a href="https://www.w3.org/about/history/">history</a>.</p><h2 id="where">Where is W3C located?</h2><p>The <a href="/staff/">W3C staff</a> is distributed around the world, but there are concentrations of people where the historical Hosts were located in Cambridge, Massachusetts (USA), Sophia Antipolis (France), Tokyo (Japan) and Beijing (China). In addition, W3C is represented by <a href="https://www.w3.org/evangelists/">W3C Evangelists</a> in various locations.</p><h2 id="funds">How is W3C funded?</h2><p>W3C sources of revenue include:</p><ul><li><a href="https://www.w3.org/Consortium/fees">W3C Member dues</a></li><li><a href="https://www.w3.org/Consortium/nmfunds/">Research grants and other sources of private and public funding</a></li><li><a href="/donate/">Sponsorship and donations</a></li></ul><h2 id="code">You found "w3.org" in the source of a web page or email</h2><p>If you view the source code of a web page or email message, you are likely to see references to W3C's web site, for example:</p><pre> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"></pre><p>or:</p><pre> <svg width="32" height="32" xmlns="http://www.w3.org/2000/svg"></pre><p>This means that the document uses a format that was standardized by W3C — in the cases above, <a href="https://www.w3.org/TR/html4/">HTML</a> or <a href="https://www.w3.org/TR/SVG/">SVG</a>.</p><p>This does <i>not</i> imply that W3C had anything to do with the creation of the document itself. W3C cannot help you identify the owner of a page that is not on w3.org.</p><h2 id="domains">What domain names are used by W3C?</h2><p>w3.org. The most common uses you will see are "www.w3.org", "validator.w3.org", and "lists.w3.org" (our <a href="https://www.w3.org/email/">Mail archives</a>).</p><p>If the domain name is something else, it's probably not related to W3C. If you find "w3.org" in the content of the page, that is likely just related to the fact that the page is HTML; see <a href="#code">"You found "w3.org" in the source of a web page or email"</a>.</p><h2 id="spam">Is W3C sending me spam?</h2><p>No. W3C does not allow its servers to be used to send spam, and unsolicited bulk e-mail is <a href="https://www.w3.org/policies/email/">strictly prohibited</a> from our mailing lists.</p><h2 id="forged">Somebody forged email to make it look like it was sent by W3C</h2><p>Unfortunately, people at times forge email addresses. Many W3C email addresses are very visible to the public, and this makes them targets for forgery. Thus, you may receive spam appearing to be sent from a w3.org address, but this only means that the address has been used to send a forged email.</p><h2 id="guest-posts">Do you allow guest posts or paid content?</h2><p>No. We do not allow guest posts and paid content on the W3C Blog or W3C Website. See "<a href="#endorsement">endorsement</a>".</p><h2 id="endorsement">Will W3C endorse my product?</h2><p>No. W3C is a vendor-neutral organization, and as such W3C does not endorse vendors or vendor products, or any particular product, service, or website.</p><h2 id="links">Will W3C link to my product from w3.org?</h2><p>W3C does not endorse any particular software. However, because it is useful to provide links to software that implements a specification, we often link to multiple products or services (thus: many, not one). If you do not find at the bottom of a page any contact information for the person responsible for updating links on that page, please write to <samp><strong>contact@w3.org</strong></samp>.</p><h2 id="validation-approval">W3C has a validation service. Does W3C approve all web pages?</h2><p>No. W3C does provide <a href="https://www.w3.org/developers/tools/">validators and tools</a>. Although validation is not mandatory on the web, it is useful for improving the quality of pages.</p><h2 id="account">Why get a W3C account?</h2><p>Much of the information on the W3C website is public, and no W3C account is needed. People need a W3C account to participate and contribute, in order to interact with the site. Visit the <a href="https://www.w3.org/account/">getting an account</a> page.</p><h2 id="lostpwd">I lost my password / forgot my account login</h2><p>You can <a href="/account/recover">recover a lost password</a> and see <a href="https://www.w3.org/account/">more information about accounts</a>.</p><h2 id="authentication">Which authentication systems does W3C use on its site?</h2><p>W3C uses a mix of HTTP Basic Authentication and a <a href="https://auth.w3.org">web form based login system</a> for resources that are restricted or personalized.</p><h2 id="rate-limiting">Why is my application being rate-limited by W3C's site?</h2><p>W3C's site receives a lot of automated traffic from software making requests for XML Schema files, DTDs, namespaces and other resources. In order to keep our site available and responsive we restrict the rate at which these requests can be made.</p><p>If you are receiving <code>HTTP 429 Too Many Requests</code> responses from our site please update your software to reduce the frequency of requests. If you are using XML processing software an <a href="https://en.wikipedia.org/wiki/XML_catalog">XML catalog</a> should help improve the performance and reliability of your application.</p><h2 id="technical-issue">I hit a technical problem with W3C's website</h2><p>Please, write to <samp><strong>sysreq@w3.org</strong></samp> with a precise description of your technical problem.</p><h2 id="system-status">Is W3C service X or Y down? (system outages)</h2><p>See the <a href="https://status.w3.org/">systems status page</a>.
